Cross-curricular Lesson Plans for puzzles and kids' mystery stories with Halloween activities

 Hello friends of the Omschool! As Halloween nears, it's the perfect time for some mysteries. Teacher Omi here with free printable cross-curricular multi-disciplinary lesson plans based on kids' mystery stories. I'm using Ghost Town Treasure for third and fourth graders and Mystery at the Docks, Robbery at the Diamond Dog Diner,  A Bargain for Francis and Something Queer is Going on Here for younger students. But these lesson plans could fit a variety of children's mystery books. 

Besides the reading, writing, STEM and social studies, these lesson plans address higher order thinking skills of synthesis, evaluation, analysis, process and outcome-based thinking, problem-solving, lateral thinking, deductive and inductive reasoning. I've also included other literature connections and Halloween themed activities. 

1) Create a treasure hunt game board game. First, establish the setting: rooms in a house, a farm or forest, your backyard, a city. Next, create a map to attach to the a folded piece of cardboard or to the inside of large flat box. You can also draw directly on the cardboard.  Make a path of footprints or squares to mark the path around the board game. Here are some free printable board game templates

Next, collect ten 3D found or recycled items that can be opened or lifted so that the treasure can be hidden under or inside. Examples: paper cup, clean food container (not clear), plastic bag, box, clean aluminum can, envelope, toilet paper tube, jar. Students should decorate items to look like things you would find in the real setting chosen (barn, silo, chicken coop, pig pen, hayloft for barn scene or tree, river, rock, bush, cave for forest scene. Don't attach them to the board. That way they can be rearranged each time you play. You will also need a very small representational treasure (coin, rock, small bag or treasure chest).A non-player hides the treasure in or under one of the places before play. 

Students will need to write a list of rules and make 20 or so cards with directions on them telling where to move the player's playing piece. To look in or under each place a player must land directly on the space. Directions to write on card  include things like: 

go forward two spaces

go backward one space

skip two spaces

move to (name hiding place)

move to the next red space

2) Play Mystery Ingredients food box challenge. You can give each student the same or different ingredients. I prefer to do different with children to avoid frustration of feeling someone else's idea was better. This is to boost creativity not competition. Winning the challenge involves using all ingredients not beating someone. Write your recipe and add it to the family recipe book. Have a tasting party. You can do Halloween or fall themed foods. 

3) Play charades having children act out different animals, occupations or characters from the book. 

4) Make an obstacle course or maze in the yard. For an obstacle course, set out different obstacles for people to find creative ways around. Make a map of the obstacle course and a list of directions: hop over the puddle, swim across the pool, scoot under the fence, swing for minutes, walk backwards up the ramp, skip down the path, step on every crack of the sidewalk, crawl through the tunnel in the treehouse. 

For a maze, arrange cardboard boxes, pillows, bales of hay, pieces of furniture, tubes to crawl through, or whatever your imagination can come up with. Make a list of directions. 

5) Play Clue or Memory. 

6) Makes your own masks or Halloween costumes. Here's my blog post of 25+ easy, homemade, no-sew Halloween costumes to make cheap or free. These are so super simple that the youngest learners can help make them. Then everyone dresses up and have a costume parade. Collect an assortment of fabric, old towels, old clothing, hats, fake flowers, buttons, ribbon, yarn, sheets, anything you can think of. The recycle bin will have lots of stuff you can use. Paper plates or paper bags work well for masks. Just cut eye holes and decorate however you want. Here are free printable mask patterns to cut and color. 

7) Play The Price is Right grocery cost guessing game. Assemble different groceries or use the ones in your mystery ingredient box. You can simply have kids estimate or arrange the groceries on the table with cards listing various amounts that they match. Put stickers with answers on the bottom. The students should  organize this game. This will teach them estimation math skills plus awareness of how much food really does cost. 

8) Sensory exploration identification game. There are several ways to play this, from easy to more complicated. The easiest way it to put an object in a bag. Kids may use all senses but sight to figure out what it is: touch, taste, smell, feel, sound. You can do this with any objects but it's especially fun to play using new and unfamiliar foods: eggplant, daikon radish, fennel bulb, broccolini for example. You don't have to hide it  then,  just have them explore it. 

Another way to play is the Creepy Halloween Foods game. This can be kind of gross and may trigger kids on the spectrum and or frighten others You put out the foods and have them touch, taste, feel and smell them then give them the spooky explanation of what they are (for example: popcorn is mummy brains). Spooky-tastic Halloween foods. Have kids write the labels and prepare the treats. 

9) Write a mystery story, cartoon or graphic novel. It can be true or invented. Illustrate and "publish" by making a cardboard cover. To make a cartoon, just fold a piece of paper in half long way and then in half again and then in half one more time. You will have 8 frames. 

10) Science Chem-ysteries. Perform some magic with my article on Harry Potter Magic tricks and Science mysteries.  Kids should assemble all materials and practice ahead of time. The only one an adult needs to do is the Magic Fire Shield of Invincibility. 

11) Kids can watch Blues Clues, Odd Squad, Scooby-Doo or Busytown Mysteries while they are drawing illustrations for their mystery story.  Youtube has Scooby-Doo episodes here. 

13) Spelling words: mystery, puzzle, clue, detective, Halloween, problem, solve, solution, explore, investigate




Harry Potter Wizard Magic Tricks, Chem-ysteries and science Experiments with literature connections

Hello friends of the Omschool! Halloween is the perfect time for some magic tricks, spells and potions, chem-ysteries (chemistry mysteries) science experiments. And the perfect person to introduce these is Harry Potter!  He can't do magic outside Hogwarts but you can with these chemistry magic tricks and wizard science experiments any time you want. Hocus pocus up some Harry Potter fun with kitchen science experiments. Teachers and homeschool parents, impress, educate and engage apprentice wizards with these chemistry magic tricks! Use these these weird science experiments for a Harry Potter Halloween party! Children's literature selections are given for follow up. Be sure to test experiments. My magic fire shield failed and I incinerated a perfectly good bandana. 

Eerie ectoplasm. Ectoplasm is really the outer surface of cytoplasm, but in paranormal speak, it's the  stuff that comes out of someone's mouth to show a spectral presence. Gross, right? Well you can make play ectoplasm with these super simple kitchen science experiments. Mix equal parts Elmer's school glue and liquid laundry starch. Work together with fingers until it forms a rubbery putty. This is also called "farting" putty (or more politely, noise putty) because air bubbles pop burps when you fold it. Like a balloon, air is trapped inside and has no where to go. Teach students that this is how you prove that air takes up space and has pressure. Read Dr. Seuss "Bartholomew and the Ooblek" or "The Cat in  the Hat Comes Back."

Alchemist Magic. Turn copper pennies silver and then gold by first cleaning them with vinegar and salt and then dipping them in zinc dust dissolved in hydrogen peroxide. They will turn to silver and then by heating them with a spirit burner you make an alloy called brass which looks like gold. This one requires adult presence. Read Rumpelstiltskin. 

Disappearing rust experiment. Clean pennies in Coke beforehand so they are shiny clean. Then posit what you used to clean them. Try lemon juice, different kinds of soda, vinegar, water, etc. You'll find that Cola words the best. Next have kids explore what ingredient none of the others have. (phosphoric acid). 

Liquid Dynamite: This is the Diet Coke and Mentos experiment. But instead of just blowing up the bottle, have students experiment with others sodas or candy to see if it works with anything else. And then explore ingredients in both that react together. Kids will learn that this is a physical not chemical reaction. The tiny holes in the surface of the candy speeds up nucleation and Diet Coke has aspartame that helps too. A narrow neck plastic bottle makes the effect more dramatic. 

Spooky Spirit Writing or Invisible Ink. Use these chemistry magic tricks to make ghostly writing appear from nowhere. Lemon juice makes the perfect invisible ink. Use a cotton swab or toothpick to write a message in invisible ink. To solve this chem-ystery and read the invisible ink, you must hold it over a warm light bulb, candle or flame. The writing will magically appear.

Rubber Bones. Prestidigitate any ordinary chicken or turkey bone into a bendable rubber bone with simple kitchen science experiments. Scrub a chicken bone clean and soak in white vinegar for 24 hours.  When you take the bone out of the vinegar, it will bend and not break. Tell students that you have cast a spell upon the bone to make it bend. The chemistry behind the mystery is that the vinegar breaks down and dissolves the hardened calcium and mineral deposits it the bone. Read William Steig "The Magic Bone."

Magic Unbreakable plastic. Tell students that you have special magic bags that will not leak even if you poke them. Fill a Ziploc bag with colored water. Seal it and then gently push a sharpened pencil through the bag and remove it. The magic is that plastic is a polymer that stretches and seals the hole so no liquid spill. Plastic actually means anything moldable. Teach kids the cute song "There's a Hole in the Bucket" or read "Basil Brush Gets a Medal."

Wizard Magic Fire Shield. Tell students that you have a magic handkerchief that can walk through fire.  Show them how you coat an old bandanna with the wizard fire shield solution. Dip it in rubbing alcohol, squeeze it out but don't let it dry. While it's still damp, hold a match to the tip of the bandanna.  Flames will engulf the bandanna but it will not burn up. After a moment, the flames will burn out and  the bandanna will be untouched. These magic tricks are obviously dangerous and adults-only science experiments. The chemistry principle that makes this work is that alcohol burns quickly and at a very low heat. It's combustible but not hot enough to burn the bandanna. This is how an alcohol burner or canned heat (Sterno) works. Restaurants use these flaming drinks and desserts (Cherries Jubilee, Bananas Foster, Greek Saganaki cheese). For a good children's literature connections, read the classic ballet story "The Firebird" or the Aztec legend of the Quetzel-coatal or Phoenix (the bird who rises from the ashes of a fire and is clothed with all the colors of the fire).

Haunted beans. These are actually called Mexican Jumping Beans and are little beans with a live  worm dwelling inside. When you hold the beans in your hand, the worm moves the beans jump and  wiggle. You can pretend to talk to the beans, ask them questions, etc. The beans will seem to move in answer to your questions. Order Jumping Beans from Amazon. 

Fairy popcorn.  Perform a similar trick with popcorn. Tell kids that an wild little sprite lives inside and wants to get out. As you heat popcorn, he escapes. Children's literature tie-ins are the fairytale "Jack and the Beanstalk" or the Greek myth "Pandora's Box" and "The Popcorn Book" (Tome DePaola).

Magic exploding rainbow. This is really chromatography or spectrum splitting science experiments. Gather an assortment of black markers of different brands and styles (water color or washable only, will not work with permanent or dry-erase). Dampen one piece of paper towel for each marker. Touch marker tips to the wet paper. Watch each ink blob diffuse and separate into an array of colors. The chemistry principle behind this is that black isn't a color but a combination of all other colors. So the ink is made up of many colors. Wetting breaks down the spectrum. Read "A Color of His Own" by Leo Lioni.

Fleeing magic fleas: Fill a pie tin with water. Add black pepper and then red pepper. The different  pepper types will repel each other like magnets. What's really happening is that the pepper is disturbing the meniscus--or molecular force that holds water inside a glass. You can show the meniscus principle by slowly over-filling a bottle. The water will actually rise above the level but stay in place by the meniscus "skin" till too much is added and it breaks. Read "The Flea's Sneeze" by Carla Firehammer. Or read Anansi the Spider African folk tales.

Genie in a bottle. Rinse a glass bottle and freeze it. Place a dime atop the bottle and then call the genie out. Slowly the dime will lift to let trapped air escape. Then the dime will clink back in place. It will repeat this several times. What's happening is that as the frost inside the bottle melts, it expands and forces air out of the bottle. Read Arabian Nights "Aladdin's Lamp" or any of the wonderful Persian "One Thousand and One Nights" stories of Scheherazade.

To round out these literature based kitchen science experiments unit, read the Norman Juster classic "The Phantom Tollbooth" along with this experiment. In the story, Milo is Bored (a word coined in the  early1960's to reflect teen response to post-war complacency). Through a series metaphorical allusions, Milo, Tock (a Watch Dog), and the Spelling Bee learn to look at things differently, to really look at things and enjoy them.

Easy, homemade no-sew cheap or free animal Halloween costumes


 Hello my friends of the Omschool? Need inexpensive Halloween costumes fast? Here are 25+ cheap, quick, easy, homemade, no-sew

 kids' animal costumes for trick or treat. Use these fast, simple improvisations for great Halloween

 costumes. You can make them from recycled household items so they will cost next to nothing.  These costumes are also warm and roomy enough to wear extra underneath--for chilly October trick or-treating or outdoor Halloween parties.

 Body for homemade no-sew animal costumes: Use recycled plain color leggings and long-sleeved T-shirt, sweat  shirt and sweat pants, blanket sleeper with feet cut out in the color of the animal the child is going as.

 Wear grey for a donkey, whale, dolphin or elephant. Choose brown for a turkey, bunny, bear, dog or  horse. Yellow works for a duck, lion, leopard, tiger, bird or Pooh Bear. Pick red for a ladybug, centipede or caterpillar. Use purple for a dinosaur or butterfly. Black works a bat, cat or dog costume. Blue can be a fish, bird, dinosaur, butterfly or caterpillar. Green is a frog, turtle, toad or snake. White works for a rabbit, cat, dog, horse, whale, turkey or tiger. And of course, tie-dye is great for a unicorn or mermaid. 

 Draw stripes, spots or other body markings on animal costumes with permanent marker, paint pen or fabric paint. To make no-sew paws, draw or paint black pads on the palms of knit gloves. For lion,  leopard, tiger or cat claws: Cut bits of recycled felt or other stiff fabric then cut small holes in gloves.  Insert part of felt piece and tie off or glue inside the glove. The part poking out will look like claws.

 You can also glue on bits of plastic cut from recycled tubs or use a set of artificial nails from a dollar  store. For hooves, webbed feet or flippers, stuff old mittens; stuff them if you wish. These homemade  paws will keep kids warm for Halloween too.

 For homemade no-sew head of animal costumes, use a cheap single-color knit hat to match costume.  Cut holes for ears. For long animal ears, stuff old pair of socks with paper. Poke open ends through holes in knit  hat. Cut slits in sock ends and tie in knots to hold in place. For stand up antennae or ears, insert loops of wire or coat hangers into stuffed socks and bend to shape for rabbit, donkey, elephant, mouse or others. For cat ears, cut paper or felt triangles, poke through holes and staple in place.

 For homemade no-sew fur, hair or mane for animal costumes, cut pieces of yarn twine 2x the desired length of hair. Tie the pieces together in the middle with one piece of yarn. (this will be the part in the  hair). Attach to top of head with bobby pins. Arrange hair around head. Cut bangs or braid if desired.

 Make tails as you did standup ears. Stuff a long sock. Insert coat hanger bent to desired shape of tail.  Pin to back of pants. Then pants can be recycled and reused after Halloween.

 Paint face with animal whiskers, nose, mouth, eyes and markings. Use Halloween face paint or your  own cosmetics. 

These homemade animals costumes are so simple to make that children can create their own. Save them for the dress up box when trick-or-treat is over.
