Sand Castle Science for Summer Beach Learning or Preschool Sand and Water Table activities

Hello my Omschooligans! Summer's almost here, yay! Parents and homeschoolers, are you looking for a way to keep the educational momentum going this summer? Look no further than the beach! You can easily turn a day in the sun into a hands-on learning opportunity by building a sandcastle.

Building a sandcastle is more than just fun—it’s an incredible multi-disciplinary activity that touches on art, social studies, earth science, and engineering. If you can’t make it to the shore, these activities work just as well in a backyard sandbox or even with an indoor sand and water table. I'll include activities and lesson plans for both beach sandcastle building and preschool classroom sand and water 

Here are five ways to gamify your summer learning:

1. Explore the Wonders of the World

Use your sandcastle construction as a jumping-off point for a social studies lesson. Research the seven ancient and modern Wonders of the World. Using a resource like the Hillman Wonders list, which features a comprehensive breakdown of the world's most impressive sites, can help you pick a structure to model. Here are some great resources for finding free printable 3D paper models of famous buildings, wonders of the world and landmarks:

• Activity Village: Excellent for printable coloring pages of world-famous landmarks, including the Eiffel Tower, the Statue of Liberty, and various sites from London, Scotland, and beyond. They also offer educational printables like world maps showing national products and sights.

• Paper Toys: A fantastic destination for a huge variety of free printable 3D paper models. You can find everything from historic castles and Shakespeare's Globe Theatre to medieval manor houses, ancient wonders, and even fun artifacts like vehicles and masks.

• Creative Park (by Canon): A highly recommended resource often used for high-quality, detailed 3D architectural models and famous structures from around the world that you can print and assemble.

• Crayola Places Coloring Pages: Offers a wide selection of free, high-quality printable coloring pages featuring famous landmarks and scenic destinations from around the globe.

• Education.com: Provides a "Color the World" series that includes coloring pages for iconic structures like the Colosseum, Chichén Itzá, and Niagara Falls, often paired with fun facts.

• In The Playroom: Offers a printable pack dedicated to the Seven Wonders of the World, featuring large illustrations that are perfect for both coloring and learning key facts.

2. Learn from Engineering Experts

To truly understand the architecture behind your creations, turn to the books of David Macaulay. I've linked to his ThriftBooks page here. His titles, such as Castle, Cathedral, Mosque, City and The Way Things Work, provide incredibly precise drawings and explanations of technological features and history. These books help kids apply basic physics to their own sand-based construction.

3. Model Your Masterpiece

After choosing a landmark, have your children draw a model of it first. Whether it’s the Mayan temple of Chichen Itza or a famous European cathedral, creating a drawing before building helps kids understand scale and structure, making the project a more intentional hands-on lesson.

4. Get Building (Engineering Science)

Head to the beach or set up a sand and water table. For a cleaner experience at home, consider a covered option like the Little Tikes Turtle Sandbox. As you build, experiment with different styles. Discuss how architectural innovations—like flying buttresses—offered revolutionary support for massive stone structures. 

5. Study Materials and Physics

Use the building process to teach earth science. Kids will quickly learn that sand is a "shifty" substance, making it challenging to build with. This is the perfect time to discuss why other materials, like wood or metal, are used in real-world construction. You can even experiment with adding adhesives to create a stronger "cement" or use items like craft sticks to provide temporary support for your structures. 

6. The Drip Castle concept in architecture

A drip sand castle is how we made them as kids before there were sand castle molds. We would collect  wet "slurry" sand with water in our hands or in a bucket. We'd slowly pour it out in out and as it began to accumulate and harden, it took on a conical castle shape. There is a precedent for this style in the church, also a wonder of the world called Sagrada Familia (Holy Family) in Spain. It looks like a giant dripped sand to form the fantastical spires of this sacred structure. 

Fact Box: Sagrada Família

Feature	Details
Full Name	Basílica i Temple Expiatori de la Sagrada Família
Architect	Antoni Gaudí (took over in 1883)
Location	Barcelona, Spain
Status	Under Construction (began in 1882)
Why so long?	Gaudí intended for it to be funded entirely by private donations, and construction was further delayed by the Spanish Civil War and the complexity of the design.
Design Style	A unique blend of Gothic and Art Nouveau (Catalan Modernisme).
Completion Goal	The main structure is nearing completion, with the final spires expected in the coming years.

Wonders of the World and UNESCO world heritage Lesson plans with printables, and hands-on crafts activities

 Hello my Omschooligans! Teacher Omi has always been fascinated with the wonders of the world. When we think "wonders of the world", we usually think of the seven ancient wonders of the world described by Philo of Byzantium and the ancient Greeks. We might wonder why these were chosen when we think of other wonders that seem more, well, wonderful. Why did they not include the much older and super cool Great Wall of China for example?

Why Those Wonders?

Because the Greeks had only traveled around the Mediterranean, they only knew of the wonders they had seen. And like most every civilization, they believed that their culture would survive forever. They had no way of knowing that none but one of their original seven, ironically the oldest and not even located in the region of what was Greece, would survive into the medieval years. ( I find this sad. I'd quite liked to have seen Pharos, the Colossus of Rhodes and the others.)

The Wonderful World of Wonders!

As time went by, travelers, historians, scientists and average citizens around the world speculated on other wonders of the world. Below are lists of the original seven wonders, plus other lists compiled over the years. Many places that that didn't make the lists have not been forgotten. The UNESCO World Heritage Sites list includes other places the deserve our respect and preservation. Here are downloadable UNESCO kits to help students learn about these wonders!

A Fun Omschool History Note

I wrote this original article in 2007, 19 years ago when homeschooling my own children! Back then, I guess I could have called it "Momschool" 😊.

Now, almost two decades later, my kids have kids and I'm Omi (grandma!) Some of the information has changed, but wonders never do! In 2007, we had wonderful opportunity to engage globally and vote in a new 7 wonders reflecting. 600 million people voted! We actually ended up electing 21 new wonders in categories of World, Nature and Cities.  And now the votes are in (including two I voted for back then)—click the links below to see who won! 

New 7 Wonders

💖

Why seven?

Seven is a holy and sacred number in many of the world's religions. In Christianity, we think of seven days of creation (and of the week), seven virtues, seven deadly sins. Other religions use seven in their worship and practice. Seven is believed to be a perfect number. So the ancients used seven and so we keep the tradition. 

Free printable lesson plans on the Wonders of the World

Engage Interest

• Time Travel: Tell students they are going to time travel. Ask children what they think a "world wonder" is, then ask what they think are the most wonderful things in the world and why. Group these into categories (Man-made, natural, newer, older).

• Visuals: Show images of the famous 16th century engravings by Maerten van Heemskerck, of the seven ancient wonders of the World. Display on overhead and read from Philo of Byzantium's diary. Use WonderClub to find images, information and printables. 

Assess prior knowledge

• Print the list of 100 top ranked wonders from hillmanwonders.com and assess which sites have been visited by students. 

• Students should check which they've visited and which they've heard of and which they'd like to visit. 

Active Learning

• Scribe Activity: Give each student a tablet and stylus (or, for a tactile experience, a piece of clay rolled thin—the original notebook and pencil). Tell them they are scribes and must engrave or draw for posterity what these lovely buildings might have looked like. Display when dry. 

  🏛️ Wonder Workshop: Ancient Crafts

  1. The Hanging Gardens of Babylon: Living Terrarium

  • The Goal: Recreate the lush, tiered greenery of the ancient gardens.

  • Materials: A clear plastic container, small pebbles (for drainage), activated charcoal, potting soil, and small moisture-loving plants (like ferns or moss).

  • The Process: Layer the pebbles, charcoal, and soil. Plant your greenery and add a few "steps" using stacked flat stones to mimic the terraced structure of the ancient gardens.

  2. The Colossus of Rhodes: Clay Sculpture

  • The Goal: Capture the massive, heroic scale of this bronze giant.

  • Materials: Air-dry clay, toothpicks (for structural support), and a base (cardboard).

  • The Process: Use the toothpicks to create a "skeleton" for your statue. Build up the clay around it. Focus on the posture—traditionally depicted with legs straddling the harbor entrance!

  3. The Pyramids of Giza: Architectural Model

  • The Goal: Explore the engineering behind these perfect geometric shapes.

  • Materials: Foam blocks, cardboard, or sugar cubes, plus small figurines for workers and ramps.

  • The Process: Construct your pyramid. Don’t forget to build a "ramp" out of cardboard leading to the top to demonstrate how historians believe the massive stones were moved.

  4. The Pharos of Alexandria: Illuminated Lighthouse

  • The Goal: Build a beacon that warns ships away from dangerous shores.

  • Materials: A paper towel tube (the tower), a small box (the base), and orange/yellow tissue paper.

  • The Process: Cut windows into the top of the tube. Use the tissue paper to represent the fire at the summit. If you want to be extra fancy, place an LED tea light inside the tube to make your lighthouse actually glow!

  5. The Mausoleum at Halicarnassus: Recycled Crypt

  • The Goal: Design a structure that combines Greek, Egyptian, and Lycian architectural styles.

  • Materials: Recycled shoe boxes, small craft boxes, and construction paper.

  • The Process: Stack boxes of decreasing size to create the tiered roof. Decorate with paper columns to give it that grand, tomb-like appearance.

  6. Temple of Artemis: Column Construction

  • The Goal: Learn about the "Forest of Columns" that made this temple famous.

  • Materials: Recycled boxes, paper towel tubes (cut to uniform lengths).

  • The Process: Attach your paper towel tubes as columns all around the perimeter of your box "temple." How many columns can you fit before it looks like a forest?

  7. The Statue of Zeus: History in Costume

  • The Goal: Visualize the scale and opulence of the original gold-and-ivory statue.

  • Materials: A doll (like a Ken doll), fabric scraps/felt, and yarn for a beard.

  • The Process: Create a toga from fabric scraps and style a yarn beard. Research what Zeus was holding—place a miniature "lightning bolt" or "scepter" in his hand to complete the look.

  ---

  🌍 The "Omschool" Master Activities

  • The Global Mapping Project: Print images of the wonders and pin them to a large wall-mounted map. Use string to connect each wonder to its location to visualize the breadth of the ancient world.

  • The Timeline Challenge: Generate a horizontal timeline on a long strip of paper. Have students place the wonders in order of their completion to see which came first, second, and so on.

  • Modern Day Mirrors: Create a "Then vs. Now" comparison chart.

    • Example: The Colossus of Rhodes (Ancient beacon of freedom) ↔️ The Statue of Liberty (Modern beacon of freedom).

• Thematic Snack: Serve dates, olives, grapes, feta cheese, and pita on a flat dish or basket.

Wrap Up: 

Students may still vote at the New7Wonders site on which wonders to include. Perhaps they'll think of something not included on a list.. For example, I voted for 

    Registan Square in Samarkand, Uzbekistan

    Lalibela rock-hewn churches in Ethiopia

 Tours Nuages in Paris

Oh and I can't leave out the giant Buddha statues around the world, like Wat Pho. And the Prachov Rocks in the Czech Republic. Or the beautiful Plitvice National Parks, Croatia or the forgotten city of Matera in Italy. Or Mount Etna in Sicily or Pompeii or Herculaneum, so many amazing places...All of these are UNESCO World Heritage Sites and so very vital to our global community.

Father's Day Party Planner kids can plan and organize

Hey my Omschooligans! It's almost time for one of my favorite holidays--Father's Day! Here's Father's Day celebration or birthday party ideas dads will love, that won't break the bank. And it can be planned entirely by children with a little help from adults. And value added, party planning keeps kids productively occupied and teaches important lessons in fun hand's on ways. 

First a word on priorities

Make it clear who the party is for. It might seem obvious that Father's Day should be dad-centered. Unfortunately, it has to reiterated. Sometimes holidays lose focus and parties end up being about everything but the person of honor. We all know that person who makes every event about themselves, even when it's someone else's special day. Let's not be that person this Father's Day. While everyone should enjoy holiday celebrations, when they are focused on one person, the party should be tailored to that person's preferences. Fit parties to the person, not the person to the party. If someone has allergies, make sure there's food for them. But don't nix dad's favorite carrot cake just because Aunt Picky-Pants doesn't like it. 

No pressure, Papa! 

On Father's Day or dad's birthday, don't put pressure on dad. If he doesn't want to dress up, for example, so what? It's his day to be comfortable. Teach kids unselfishness. In parenting, everything can be a teaching tool--even parties. Kids will be as selfish or selfless as they are taught to be. Demonstrate to kids that parties are meant to convey love. If he wants to do the grilling, let him. If he wants it simple, keep it that way. 

💭Funny Omi Memory: when I was a kid, we made ashtrays, pipe racks and ties for dads! Times have changed!

Dad-friendly Fun

On Father's Day, do things dad enjoys. I (and two of my kids) find fishing achingly boring. But my husband loves it. I remind the non-fisherfolk (and myself) how often he does things he hates for us. So we all went fishing on Father's Day. The kids felt good doing what made daddy happy. That's paid off in character as they've gotten older--each is very others-centered. You could also 

• play badminton, corn hole or lawn croquet
• do a group craft project 
• have a card making station
• chalks the walks with a Happy Father's Day mural

Pamper and personalize 

List with kids, all daddy's favorite snacks, hobbies, reading material, special interests, movies, music. Make a themed gift basket of his favorite things. Does dad love his truck? Make a truck-themed gift basket with cleaning supplies, accessories, manual, logo T-shirt and cap. 

Fiesta! 

Very few men don't love to eat. Indulge dad's tastes, no matter how weird. And the men in my family redefine weird food tastes! My husband loves deep-fried okra. My dad liked suet pudding. Grandpa loved head cheese. So we do a "food shower" for dads and grandpas. One year, we made a New Orleans Father's Day brunch with beignets, Cafe du Monde, jambalaya, gumbo, catfish court-bouillon and etouffee. Dad got a personal bottle of Tabasco Sauce. 

Party outdoors

BBQ, picnics and camp-outs are dad-favorites. Can't get away? Set up tents in the backyard. Make (or buy) a fire pit. Set up an outdoor buffet. Grill (let dad do the grilling if he enjoys it or wait on him). Make a dad-pleasing Coney Island hot dog bar. Roast wienies over fire. Set out chili, sauerkraut, hot peppers and condiments. Whip up homemade cole slaw (chopped red and green cabbage, carrots, colored peppers, onions dressed with olive oil, horseradish, apple cider vinegar, celery seed, salt and sugar). 

Airfry or deep-fry French fries (deep fryers and air fryers are great dad gifts)

Serve watermelon (have a seed-spitting contest)

Make a German chocolate cake with coconut frosting.

Sip root beer floats. 

Get dad a 6-pack of craft beers. 

Homemade and cheap

Most dads don't want a lot spent on them. And Father's Day isn't about that. One year, we made dad a T-shirt. I bought washable crayons and kids drew pictures and signed it. Another year we did a handprint sweatshirt. Kids could decorate a stadium chair, beach towel or blanket. I made a blanket with our homeschool group of kids for our priest. He still uses it.

School Festival party planner for year end and back to school parties

Hello my friends! Did you get wrangled into planning the end of school year party? If you are in charge of hosting an event, party or festival of any magnitude, say for work, school, church or an organization there is a basic plan you need to follow to attend to all the details. Here is a 'schedule' of tasks.

Two Months before the event:

Check on any licensing you may need. Chances are, there is nothing to worry about, but if you will need to check on permit for:

selling items or tickets - IRS, (are you 501 C3 status? non-profit?)
raffling items or money - gaming commission
selling or serving alcohol - zoning, licensing, age restrictions
selling food - health department
lighting candles or having a fire (marshal approval)
transportation, rides, hayrides, inflatables (Moon Walks, etc.) insurance issues; city ordinances or codes
animals - health codes; ordinances

In general, check the blanket policies of the organization you work with or under. What are your by-laws? Group codes? etc.

Delegate: Depending upon the size of your event, you will need to assign tasks. If you are an organization and you have a board, each board member can take the task that fits their role. Ask for RSVPs and volunteers. Don't try to go it alone! Let others share their talents. .

Get the word out: Insert newsletter or bulletin announcemenst, print and post flyers, or start a phone chain or email invitiations. Will you invite the general public or have a limited guest list? Set up a table after school, after church or activity meetings.

Take an informal head count: How many will be involved? How many children and what ages? Will it be a family affair?

Determine your budget: What is your overhead? Will you collect donations of food, supplies, etc? Will you need to charge money? Will you sell tickets? Will this be a fundraiser of some sort?

Find a location: A large basement? A church hall? A school gym? A barn? Will you need to rent a facility?

Decide upon activity locations: Outdoor, indoor or both? Will you have scavenger hunts, hayrides, hay mazes, etc that will be outside? Consider your local weather.

Network your volunteers: How many activity helpers will you have? Who donate food, craft supplies, etc? Who could cut out, assemble or design items you'll need for activiites? Will you need shoppers? Phone callers? etc. I like to call upon senior citizens who might like an opportunity to be involved.

Prepare your agenda: ( see sample below) How many activities? Who will man each one? How will you arrange space? Where and when will people eat?

Assign coordinators: Consider this: make each game or activity coordinator responsible for preparing a list of supplies and prizes and making or gathering materials. If one family or person takes care of each activity it will run smoother and not be overwhelming for a few folks. Family members can take turns manning the activity so everyone can participate. Give each coordinator a budget or spending limit based upon your initial budget analysis. A simple way is to divide your activity budget by the number of activities. (ie $200- 10 activities = $20 each). But do remember that some may cost more.

Circulate order forms and place a bulk order: Give each coordinator time to plan their activity and list what will be needed. If you will order from a catalog, ask that supply or prize lists be in about three weeks ahead of time. Send bulk order from whichever catalogs or online sources you use.

Consider purchasing durable goods: This might be a good annual event. If you buy game supplies, like a bean bag toss game, store them from year to year.

In the week ahead:

Send out reminder texts, group chat or emails.

Shop for food and store supplies. Freeze perishables.

Decorate area. Don't inflate anything until the day of the party. Inflatables lose air overnight.

Set up games, activities or booths.

Check for anything you might be missing.

Put in a last newsletter/ bulletin reminder.

Most of all, remember to have fun yourself!

Use these free printable measuring tools in "Nature Detective" kits

These resources are excellent because they are designed to be printed, cut out, and taped together to create a full-length measuring tape:

• Printable Rulers & Measuring Tapes: This site offers a great selection of PDF templates, including one-foot rulers that feature both centimeters and inches, as well as metric-only options.

• LabelValue Free Printable Ruler: This resource is designed to be printed to scale (be sure to select "Actual Size" in your printer settings) and includes both inches and centimeters.

• Timeless Templates: They provide specific downloads for both inch-based and metric measuring tapes, which are very useful for DIY assembly.

Important Tips for Accuracy

To ensure these tools are accurate for scientific observation:

• Print at "Actual Size": When printing, always check your settings to ensure the document is set to "Actual Size" or "100% scale." Do not select "Fit to Page" or "Shrink to Fit," as this will alter the measurements.

• Verify Scale: Most of these PDFs include a way to verify accuracy—often by comparing a printed inch to a real credit card or a known ruler. It's a great "quality control" step to have the students perform before they start their investigation!

  
  
  

Printable Animal Tracking Guides

• Animal Track Identification Guide (Town of Thornton): This is a fantastic, comprehensive PDF guide featuring black-and-white sketches of various North American animal tracks. It is perfect for printing and keeping in a nature kit.

• New Hampshire Fish and Game Pocket Guide: A very practical, foldable "pocket guide" that provides a quick reference list of track sizes for many common animals.

• Animal Tracks Printable Book & Cards (PreKinders): Designed specifically for younger learners (preschool/kindergarten), this resource includes a printable book and matching cards, which are excellent for learning games and building early identification skills.

• Animal Tracks Printable Cards (Fox Farm Home): These cards are perfect for interactive outdoor play. You can punch a hole in the corner and put them on a ring to take on the trail, or use them for memory matching games at home.

• Virginia Soil and Water Conservation Districts Guide: This is a clear, text-and-line-drawing-based guide that explains key identification features like the number of toes, stride patterns, and claw impressions.

Pro-Tips for Your Tracking Adventures

• Laminate for Longevity: Since tracking is an outdoor activity often done in mud, snow, or damp conditions, printing these on cardstock and laminating them (or covering them with clear packing tape) will keep them protected in the field.

• "Nature Detective" Kit Hack: Have the kids create a "Track Viewer" by cutting a square hole in the center of two pieces of cardboard (as suggested in some of the links above). This helps them focus on a single set of tracks at a time, making it easier to notice details like size and shape without getting overwhelmed by the surroundings.

• Journaling Observations: Encourage students to draw the tracks they find in their nature journals. Even if they can't identify the animal immediately, sketching the shape, noting the number of toes, and measuring the stride (the distance between tracks) is exactly what professional field biologists do!

Printable Tree & Leaf Identification Resources

• Woodland Trust: Nature Detectives Spotter Sheets: This site is a goldmine for young investigators. They offer a wide variety of PDF spotter sheets, including:

  • Leaf ID Sheet: A clear, easy-to-use guide for identifying common tree leaves.

  • Twig, Blossom, and Fruits & Seeds Sheets: Great for expanding your kit beyond just leaves to include identification in all seasons.

• JDaniel4's Mom: Leaf ID Chart & Cards: This set includes a chart and individual cards that you can punch a hole in and put on a metal ring—perfect for carrying around on a trail.

• Educate Outside: North American Leaf Identification Cards: A beautifully illustrated set of cards featuring 16 common North American tree leaves, designed specifically for teachers and students.

• Imperial College London: Tree Identification Guide: A more detailed, 8-page guide that is excellent for older students or those who want to learn the specific terminology of leaf shapes, margins, and venation.

Tips for Your Tree Investigation Kits

• Specimen Sorting: If you have collected leaves, have the kids use their identification cards to "sort" their findings. Laying the collected leaves out next to the corresponding cards is a fantastic way to practice categorization skills.

• Seasonal Focus: Remind your detectives that trees change throughout the year. If you are doing this activity in winter, try to focus on the twig identification sheets, as many trees will have dropped their leaves by then!

Using Nature Detective Kits:

• Make kit assembly part of the lesson. Set out supplies in stations and give students gallon zipper bag and supplies list. This provides experience in counting, sorting and organizing.

• Using stickers, kids label notebook: Investigator (name)____________ or Detective (name)____________. Label bags: Exhibit A, B, C or Evidence. As evidence is collected, data and date should be added. For example: 'beetle exoskeleton 9-3-2015.

• Go on nature investigation hunts around your neighborhood, school playground or camp. Assign students different items to investigate, native to your area. 

• Students should not keep living specimens, but they might bring a bug box to temporarily house and examine a living critter.

• Look for evidence of living creatures: 
• bug carcasses
• exoskeletons
• fallen leaves
• feathers
• owl pellets
• seed pods
• rocks
• fallen nest
• bits of animal fur
• bark samples
• plant parts
• wildflowers (pick just one)
• rocks.

• Have students draw living creatures, homes and habitats: spider's web, bird's nest, wasp's nest, rabbit hole, ant hill, scat (animal droppings). 

• Students should record when and where they observed it. Students shouldn't touch but may observe scat (animal droppings) or dead animal remains. 

• In class, have children discuss and hypothesize on findings at their level of reasoning. 

• Students might create a natural history museum displaying what they have found. Students can act as young docent guides, explaining discoveries to visitors.
  
  
  

Nature Detective Measurement Activities

• "Size of the Find": Have the students measure the length or width of items they have collected (e.g., leaves, rocks, or pinecones). They can record these measurements in their one-subject notebook next to their "Exhibit" label.

• "How Tall Is It?": Use the large-print metersticks to measure features that aren't easily collected, such as the height of an ant hill, a patch of wildflowers, or even the diameter of a tree trunk.

• "Scale Estimation": Before measuring, have students hypothesize the size of an object. This builds scientific reasoning skills. Ask: "Do you think this leaf is longer than 5 centimeters?" Then, have them use their printable ruler to check their guess.

• "Life-Size Illustrations": Challenge the students to draw a creature or plant exactly to scale in their journals, using their rulers to ensure accuracy.

• The Big/Small Hunt": Challenge students to find the smallest leaf and the largest rock in a specific area. Use their printable rulers to record the exact difference in size between the two.

• "Tree Diameter Challenge": Since it's hard to measure a tree with a straight ruler, teach them to use a piece of string to wrap around the trunk, mark the length, and then lay the string against their ruler to find the circumference.

• "Growth Tracker": Pick a specific plant (like a wildflower or a small sapling) and mark it with a small flag or stick. Have the students measure it once a week to track how much it grows over the course of the season.

• "Shadow Measurement": Trace the shadow of a stick at different times of the day (morning, noon, and afternoon). Measure how the length changes as the sun moves across the sky.

⚠🔬Pro-Tip for Success: Remind them that in the world of science, accuracy matters. If they are measuring a bug, they should measure from the "head" to the "tail" consistently every time so they can compare their data with their friends' findings later!

Omschool Tips for Your "Nature Detective" Kits

• Durability: Since you are doing this outside, print your rulers on card stock then laminate them (or using clear packing tape over the paper) to make them moisture-resistant. 

• The "Transparency" Hack: If you have access to a printer that can handle clear sheets, print the rulers onto overhead transparencies. This is a favorite among teachers because it makes it much easier to measure "odd" or squishy things like leaves or flowers without damaging them!

• Calibration Check: Before heading out on the trail, have the students perform a "quality control" check. Use a standard credit card or a known object to verify that everyone's ruler was printed at 100% scale.
