10 Science lesson plans from recycled egg cartons

 

Hello my friends of the Omschool! April is Earth Month with April 22 being Earth Day. The purpose of Earth Month is to bring our focus to conservation and preservation of our earth's natural resources. When Teacher Omi was young we called this Arbor Day (aka Tree Day) and a common activity was to plant a tree. Earth Day has been expanded to include the many areas in which we can practice earth-healthy activities like conservation (also called ecology). 

Teachers and homeschool parents, there are so many great environmental lesson plans you can use to celebrate Earth Month. My favorite Earth Day activities include practicing ways to reduce, reuse, repurpose and recycle the many items we use in our everyday lives.  We teachers have a special responsibility to teach earth-friendly habits in how we ourselves repurpose found materials, reduce waste and consumption of resources, reuse items on unique ways and recycle every possible scrap. Because while we focus on these disciplines particularly in Earth Month, we need to be  demonstrating them all year long. 

Probably the most effective recycling lesson plan is to used recycled trash as classroom materials. I like to use a visual such as a trash bag filled with reused items, to show students how much landfill waste we saved. You can make it a game or personal challenge to students to see how many ways they can repurpose, reuse, reduce and recycle. Assign them to list in science journals how many conservation activities they completed each day. 

And when it comes to materials for craft projects and lesson plans, your recycle bin is your best friends. I've got loads of ideas to share on how to reuse various recycled items but today I'll focus on the ubiquitous egg cartons. Here are some ways that teachers and students can repurpose recycled egg cartons as science experiments, science games and science crafts.  This will save money and reduce pollution. 

Attribute sorting science activities and games

Sensory exploration is the core of science and a key component of preschool and Montessori education. Students can practice sensory exploration in hands-on science games. To play, pass out clean, recycled egg cartons--paper, plastic or Styrofoam-- with each section labeled with words or pictures of attributes. Attributes listed will depend on materials being sorted and science subjects being studied. Items may be sorted by color, shape, size, living/non-living, wood/metal/plastic, etc. You can play this as a scavenger hunt in which students search for objects--preferably recycled-- to fit each attribute category. Labeling and sorting materials into recycled egg cartons builds science vocabulary, adjective usage and description.

Sensory Exploration sorting science games for preschool lesson plans

Sort edible items by:

   *Taste: Sweet, sour, salty, bitter, fruity, tart

Sort edible and non-edible by:

   *Smell: spicy, bitter, sour, soapy, flowery, fruity, moldy, metallic, woodsy, earthy

   *Touch: furry, fuzzy, smooth, cool, warm, hard, rough, scratchy, bumpy, squishy, sticky

   *Sound: squeak, ring, buzz, beep, pop, clang, snap, crackle, scrape, scratch

Ecology experiments using recycled egg cartons.

Paper or Plastic? Use cardboard and Styrofoam recycled egg cartons to demonstrate what happens to both in a landfill. Place a piece from each carton in water and soil put them in the window. Note any changes to each over time. Use this to explore biodegradable materials and renewable resources for Earth Month. Discuss how pollution is an environmental hazard and harms plants and animals.

Geology science experiments for Earth Month:

Use recycled egg cartons to classify and identify rocks and minerals. Here are free printable rocks and minerals identification charts to download and use. Here's are more free printable rocks and minerals guides with beautiful color illustrations. Students should label the sections of recycled egg cartons and sort by:

hardness on the MOHs hardness scale (use this free printable MOHs scale)
rock type (metamorphic, sedimentary and igneous)
mineral composition (calcite, silicate, carbonate, etc.)
uses (building, abrasion, decoration, chemistry, etc.)

Eco-Friendly Printing Tip

Since you’re already repurposing egg cartons, here’s a quick tip to keep the rest of your science lesson just as sustainable:

Pro Tip: To save paper and reduce waste, print your worksheets and charts on the blank side of used paper. To save on ink, print in grayscale (black and white) unless the images are essential, and select the lowest saturation or "draft" setting on your printer.

Biology science games. 

Label the sections of recycled egg carton science crafts with taxonomy classifications from the kingdoms (plantae, animalia, etc). Use these free printable animal taxony charts. Students might sort by subcategories 

KPCOFGS (kingdom, phylum, class, order, family, genus, species). 

Students might cut out pictures or make tiny cards with names of members of various groups. Then they can sort pictures or words into categories. They can test each other in partners or in groups. Label the bottom of the egg carton with answers for self-checking. This can be adapted to any age or grade depending upon what you are studying.

Quick Tip: Mastering the Taxonomy Hierarchy

Memorizing KPCOFGS (Kingdom, Phylum, Class, Order, Family, Genus, Species) can be tricky for students. Use this classic mnemonic to help them remember the order from largest group to smallest:

"King Philip Came Over For Good Soup"

• Kingdom

• Phylum

• Class

• Order

• Family

• Genus

• Species

Systems science crafts. Most all science experiments are based on a system or cycle. Use recycled egg carton science crafts to make 3D flow charts or graphic organizers Places objects in each section to represent parts of the cycle and draw arrows to show how they interact. Demonstrate electrical current, the water cycle. food chains, human body systems, habitats, plant development and insect metamorphosis.

Science Timelines. Use recycled egg cartons to demonstrate how things change and develop (or regress) over time. Make timelines of science inventions, transportation, etc. Use this with any area of science that you teach.

Students find science experiments boring when they engage in same-old activities. These homemade science crafts and science experiments will challenge and intrigue students while also providing opportunities to practice vital conservation and ecology skills. The simple act of recycling works to improve all aspects of conservation: deforestation, global warming (climate change) from greenhouse gasses, over-consumption. We even practice wildlife preservation every time we reuse, repurpose or recycle instead of discard! And that improves all our lives. 

Make a pet baby tornado: fun, easy, free science activities and recycled crafts

 Hello teachers and homeschool friends, "Omschool" teacher Omi (grandma) here with easy, free recycle bin crafts for science lesson plans. Today we're making pet baby tornadoes. This science experiment is easy for all ages from toddler on up. It's perfect for a highchair craft. The pet baby tornado is free to make with items from the recycle bin. You just need water, a clean glass jar with lid and a tiny drop of dish soap. 

To find baby tornado, just shake round and round to create a swirling in the water, called in science talk, a vortex. This is the force that drives a whirlpool and also the force that is generated by the drain in your sink or bathtub. Water doesn't just fall down the drain, it swirls round and round as it goes down. 

I realized after I made my pet baby tornado video that it was difficult to see him clearly. So I tried adding a little food coloring to make baby tornado show up better. You can also add some glitter if you  have some, to show how things floating on the surface are pulled into the vortex. 

 

Extend your science fun with some cross-curricular connections. Make a book about baby tornado. Research tornados and the force they create. Draw your tornado and maybe make up a song about him (her!) 

Here are free printable tornado lesson plans from A to Z Teacher. And here are some more free printable tornado lesson plans from Teach Engineering. 

DIY Sand and Water Table alternatives for homeschool and classroom

 Hello fans of my Omschool blog. I've been a licensed general and special education teacher for 37 years and part of my career work was spent homeschooling our four children. Now, I'm Omi--grandma--to 9 going on 11 and am continuing the homeschool traditions I began, with the second generation as Omschool (Omi's school). Lesson plans are designed with cheap to free materials, many of which are reused, repurposed and recycled. 

For today's lesson plans, we'll create a DIY sand and water table for preschool, special education and lower elementary learning centers. This sand table alternative was developed in our homeschool and works well for small spaces. As budgets are usually tight, whether in public, parochial or homeschool, this is a low cost alternative as well. 

Instead of the expensive sand and water table purchased from school supply companies, I've used a repurposed child's sandbox such as the enclosed Little Tikes turtle sandbox or Step 2 brand sandboxes. The turtle sandbox is washable, portable and covered. It moves easily indoors or out. For an even more budget friendly alternative, get a small plastic wading pool. I've found these as cheap as $7 from Dollar General. Inflatable kiddie pools will work too however they aren't as durable. 

The last sand table alternative is a low sided plastic box or tub with lid. This works very well when space is limited. When learning center activities are done, simply close the box with media and manipulatives inside and stack in the storage area. Here's my blog post on homemade sand toys for the sand table. 

These preschool learning center activities worked very well for our homeschool. I could allow the  youngest children to explore independently while instructing the older children. The DIY sand and water table wasn't just for preschool learning center activities either. The older kids could use it to practice and explore mathematical concepts such as measurement, geometry (volume) and science (sing various media). Sand tables provide excellent sensory experiences. More on sand table filler alternatives later! 

I'm sorry I don't have an image of how this sand and water table fit in our homeschool. But let me assure you the even in our tiny 10x10 room, it fit well! I've linked the picture to Amazon. This small reasonably priced Step 2 sandbox would work perfectly. 

Recipes for homemade crayons using recycled broken crayons

With Earth Day, and Earth Month, fast upon us, I'm looking at ways to reduce, reuse, recycle and repurpose .Making crafts with recycled materials from the recycle bin is an excellent way to teach Earth Day eco-friendly habits. Here's are activities to use up those leftover broken crayons. Repurpose them as new crayons with these simple science activities. 

Have students gather broken crayons and peel off outer paper. You'll be making new palm held crayons similar to the egg crayons. These are popular in special needs or preschool classrooms use to help children who aren't quite ready for the stick crayons. Palm or egg crayons help toddlers, preschool and special needs kids develop fine motor skills while still enjoying coloring activities. 

Once you have pile of peeled crayon pieces, spray old recycled muffin tins with cooking spray. Use mini muffin tins for preschool and older children and large ones for toddlers as mini shaped crayons might look edible to toddlers. Have students place assorted bits of broken crayons in each tin. Aim for a rainbow of colors in each cup. Help kids place muffin tins in oven and heat to 200. Heat till crayons on melted but still chunky. Swirl with toothpick while warm if you wish. Place crayon melts in refrigerator till hardened then turn out of pan and enjoy coloring.

Be sure to only use recycled muffin tins for crafts, and not cooking, once you've done this activity. This is a great way to repurpose old muffin tins and give them new life. Use these free printable rainbow coloring pages to make beautiful spring crafts. Print coloring pages and printables on scrap paper from recycle bin for green, Earth Day ecofriendly activities. 

St. Patrick's Day party lesson plans, crafts, activities to celebrate green

Here's a nifty unit of activities for St. Patrick's Day: lesson plans to celebrate all things green! I've tailored these lesson plans for classroom or homeschool, and ages toddler and preschool through grade 3. I've included St. Patrick's Day party activities, green themed food and snacks, games, crafts and printables. There are many earth science extensions for Earth Day too. 

Green themed snacks and food for St. Patrick's Day party: 

Make a green fruit and vegetable tasting tray. For hands-on biology science activities, explore plant parts of green veggies and fruits. Make a chart to show what plant part each comes from. Draw a large tree showing roots below the ground. The use these free printable coloring pages for fruits and vegetables to color, cut and paste pictures on the tree. 

Roots: sprouts, scallions (tops), fennel bulb

Stalk (trunk) celery, green onions, dill weed, asparagus

Leaves: lettuce, brussels sprouts
ts, kale, spring mix, arugula, spinach, cilantro, mint, watercress, 

Seeds: green beans, peas, edamame, 

Flower: Broccoli, broccoflower: flower 

Fruit: cucumber, kiwi, green grapes, green beans, zucchini, chayote squash (also called mirliton in southern states), green apples, pears, acorn squash

Students will enjoy making green lime yogurt pops by freezing yogurt in popsicle makers. Or freeze limeade or pistachio pudding. 

St. Patrick's party games: 

Play Red light/Green Light (basically stop and go). Extend with safety lesson plans. Discuss that green represents "safe" or "go" in online, cyber and traffic safety. Make traffic safety road signs to test children. Use these free printable traffic signals and road sign coloring pages. 

St. Patrick's Day green themed crafts

Discuss earth friendly ways to keep the earth green. Encourage kids to think reduce, reuse, recycle and repurpose. Challenge them to make "green machines" that are both eco-friendly and green in color, from the recycle bin. 

Toddlers and preschool students will like to color these free printable spring coloring pages. Here are free printable flower coloring pages too. Be sure to print on scrap paper from the recycle bin. Use low ink settings for the most eco-friendly printing. Assemble into a poster to display. 

Have children make collages from recycled magazines of pictures of things that are green. For really earth friendly green crafts, use materials from the recycle bin. Toddler and preschool children will love finding green items in magazines. 

Plant herb seeds in recycled jar or plastic dish (holes poked in the bottom for drainage) from recycle bin. 

Earth Day green outdoor activities

Go on a nature hunt and look for spring signs of new life: nests, buds on trees, green plant shoots, flowers beginning to sprout, grass growing, baby leaves on trees. Pay special attention to things that are green. Kids should bring a nature journal where they can draw pictures of what they observe. 

Collect litter and trash for proper disposal. Be sure kids wear nitryl gloves and masks when collecting litter. Adults should collect any glass. 

Lesson plans using recycled plastic Easter eggs and egg cartons

  I love repurposing and reusing stuff from my recycle bin in new and creative ways, especially as lesson plans. Recently, my one-year-old grandson has been discovering the fun playing with empty recycled plastic Easter eggs. This has inspired me to design hands-on activities, lesson plans and games using recycled plastic Easter eggs and egg cartons. I've includes some free printable activities to supplement. 

With Easter coming up, there will be many activities involving plastic Easter eggs: candy hunts, Easter crafts, etc. You might be tempted to throw them away, after use, but don't. There are so many educational activities to use recycled plastic Easter eggs. Save Styrofoam egg cartons as well. 

I blogged in an earlier post about using plastic eggs and egg cartons from the recycle bin as preschool learning center math, sorting and fine motor activities. The good news for homeschoolers is that these make great toddler high chair activities too. Activities are easily adjustable to age. My grandkids Juno and Emmett who are 1, love stacking or "nesting" plastic egg halves, just like blocks. We work on placing eggs in egg cartons, to practice eye hand coordination, puzzle skills and fine motor. 

Challenge kids fine motor skills in egg assembly activities. The plain colored recycled plastic eggs are easier than the shaped ones like the ice cream ones shown in the picture which can be a little tricky. But it's important for development that some tasks be difficult, especially for special needs and students with autism. We teach to fear failure and frustration when we make things too easy, or do it for them. Children need challenges, to have to work at something and to try new approaches, to learn patience, perseverance and vital problem solving skills. 

Use assembled Easter eggs in science learning centers and preschool sand and water table to explore water displacement and floatation concepts. Give toddlers scooping tools to practice fine and gross motor skills in high chair activities. Special needs students will love "fishing" for Easter eggs too! 

Have kids "hide" little items or non-messy foods in recycled plastic Easter eggs. Or hide them yourself and have students predict what's inside. This teaches math skills of size estimation. 

Sort eggs in egg cartons, by color or design. Last year, when my husband and I visited our grandkids, we brought each child a set of individualized themed Easter eggs (dinosaurs, fish, desserts, sports balls and insects). Then we played an Easter egg hunt game in which each child had to find eggs in his pattern. The 3-year-olds, Lucian and Milo, were able to identify eggs that belonged in their pattern. And Ezra, who was almost two, was able to find his fishy Easter eggs by their color. Extend pattern lesson plans with free printable animal dominoes. 

Do an Easter egg hunt, using recycled egg cartons to place found eggs. Each child brings a dozen and finds a dozen. Once her 12 spaces are filled she "wins." A homeschool mom friend of my oldest daughter came up with genius plan. It prevents kids taking too many eggs and best of all teaches math skills. Have older kids group their eggs by two, three, four and six, to learn skip counting, multiplying and dividing. Reinforce with these free printable math flash cards.

Recycle bin Easter egg crafts to teach early math--with free printables

With Earth Day (now actually Earth Month) around the corner, I'm sharing lesson plans to make crafts from your recycle bin. Today we're making recycle bin Easter egg crafts to teach early math activities of sorting and matching, plus fine motor skills. These Easter egg crafts were inspired by my toddler grandchildren, Juno, Ezra and Emmett. 

As a homeschool mom, I was always looking for toddler high chair activities to keep the youngest busy learning while I did lesson plans with the older kids. Use these Easter egg crafts in math learning centers, as high chair activities or at a toddler picnic table for older more mobile preschoolers. I used one of the small Little Tikes picnic tables with our youngest. I rotated different preschool crafts and hands-on activities for her to work on. You could use the sand and water table also. 

For toddler Easter egg crafts (ages 1-2)  you're only going to need two things, which can be found in your recycle bin: plastic refillable Easter eggs and empty egg cartons. Assemble eggs for 1-year-old children and let them practice sorting into egg cartons. As they get older, children can begin assembling Easter eggs. Then at age 2-ish, they can match egg halves by color or pattern (we have some really cool ones shaped like sports balls, fish and ice cream!) These are great for developing fine motor skills. And saving Easter eggs from year to year is environmentally friendly so prefect for Earth Month. 

Also at age two, or whenever they no longer put things in their mouths, they can begin filling Easter eggs with tiny objects or shapes. Children might cut shapes from recycled cardboard or paper, to practice scissors skills. They might also use shape punches. Extend this into a fun preschool snack craft by giving them little snacks to hide in eggs (fish crackers, letter pretzels, etc.)

Here are free printable Earth Day activities and here's my page of free printable Earth Day lesson plans, crafts and activities. Lastly, here's my collection of lesson plans for Earth Day trash crafts Stay tuned for more Earth Month activities! 

Medieval history lessons plans: Cardboard castle crafts, princess crafts with printables

I am a self-avowed history fanatic, particularly the medieval period. I also love things princess. And being a teacher, homeschool mom, education blogger and now Omi (gramma), I'm always looking to create hands-on lesson plans.  To that end, here's a guide to making recycled cardboard castle crafts with free printables. Use these are recycled cardboard crafts for kids in many cross-curricular lessons: preschool learning center activities, theater and dress up fun, arts and crafts, STEM and history lesson plans. These medieval crafts include a homemade cardboard castle, costumes and props. Homeschool parents, I promise ways to engage all ages, from baby to teen! 

(Materials are noted in BOLD CAPS within the how-to guide)

1) Make cardboard castle walls. Cut open two large RECYCLED CARDBOARD REFRIGERATOR BOXES along one long side. TAPE (duct tape works best as it resembles grey stone) two boxes together to make an octagon castle "keep." Measure, draw out and cut cardboard castle battlements (great STEM activities). History note: Castle walls had a series of crenellations and merlons (squared edge thingies) along the top. Tim's Printables has free printable recycled cardboard castle patterns for medieval crafts and castle design ideas. Cut cardboard castle keep windows: Draw a four-pane window and cut openings for the princess to look out of. 

2) Decorate recycled cardboard castle. Draw in bricks and family crest to make these medieval crafts for kids look really authentic! For more STEM fun, make moat and drawbridge. Cut drawbridge opening in the side of cardboard castle. Attach YARN or ROPE to both sides of to lower and raise drawbridge. Cut holes in the top to tie drawbridge closed when the royal inhabitants aren't receiving company. Place BLUE BLANKETS around the outside for the castle moat. Fill with STUFFED ANIMALS dragons, fish, alligators and other aquatic creatures. Add some PLANTS to make it more realistic and discuss wetland habitat science. Toddlers and preschoolers can take on the job of gathering and arranging flora and fauna.  

3) Make flags for cardboard castle. Aristocrats and nobles in medieval times had a coat-of-arms or family crest that symbolized their lineage. The design and display of a coat-of-arms is known as heraldry. A coat-of-arms was placed on banners flown when the family was in residence. Banners were carried on standards into battles. Have kids design their royal family crest. Here are free printable heraldry patterns and stencils for medieval crafts for kids. Make banners on  SCRAP FABRIC SQUARES CUT FROM OLD BED SHEETS OR TOWELS. Attach to YARD STICK OR HOT DOG STICK. Draw or paint family crest using MARKERS OR FABRIC PAINT. Older kids can make these as history lesson plans. 

4) Make secret entrances for your recycled cardboard castle (my grandkids favorite part!)  Line chairs up to make a crawl-through tunnel entrance into castle. Drape sheets, blankets and bed linens over tunnel. Establish cardboard castle dungeon. Make a parapet (walkway) by placing several chairs or a bench along the inside edge of the castle. Soldiers keep lookout here and send prisoners to sit under the chairs in the dungeon sit under bench. Fashion a turret. Put a collapsible net laundry hamper upside down on a chair inside the castle. Children crawl into hamper and onto chair to look out of the turret. These are perfect jobs for youngers. They will love exploring, arranging and guarding the cardboard castle as part of their dramatic play learning center activities. 

5) Outfit your royals. Haul out the DRESS UP BIN and collect OLD TOWELS, BED SHEETS AND BLANKETS. Donate JUNK JEWELRY and OLD FANCY DRESS. Make recycled cardboard crown crafts for the princess with these free printable crowns from First-Palette. Use this guide to make a suit of armor cardboard crafts for a knight. More STEM lesson plans! 

6) Equip the keep. The keep is the living area of a castle. Let kids fill their cardboard castle keep with snacks, blankets, pillows, coloring supplies, books and pets. When the novelty of guarding the castle wears off, kids can use it as a cozy play fort. Set your homemade castle up in a place where it can be left up for other rainy day fun or make it convertible to go outdoors on nice days!

Stay tuned for more medieval crafts! Picture is courtesy of Free Coat of Arms (couldn't find my last name, alas!)
