Homemade Silly Putty Recipe

Way easy. Equal parts white school glue and liquid starch. I use 1/2 c. of each. Add a few drops of food coloring to get the desired color. Stir it up and you'll have your very own silly putty!

Best done over tile, kitchen counter or table.

Recycle It Tip: Save large empty cereal bags, cut open to form a large playmat or placemat. It'll make clean up easier!

Homemade Bubble Wand


Tape several straws together. That's it! Make hundreds of tiny bubbles or blow slowly to create a foamy tube of bubbles. Since we used bendy straws, C thought it would be funny to bend the ends and send bubbles in all directions.

WELCOME AUTUMN
To the tune "London Bridge"

Autumn leaves are falling down, falling down, falling down,
autumn leaves are falling down,
welcome autumn.

Sweep the leaves and put them here, put them put here, put them here,
Sweep the leaves and put them here,
welcome autumn.

Jump right in and have some fun, have some fun, have some fun,
Jump right in and have some fun,
welcome autumn.

River Treasure


We took the boys to the river and let them explore. Our best find was amongst the little pebbles on the shore. The boys came home with pockets full of everything from agates to crawdad claws. I let those little fingers dig and explore in the tiny pebbles for obscure "treasures" and was sure to empty pockets before wash day.

Exploring Sunflowers



The sunflowers are starting to droop and I decided to let C do a little sunflower dissection. They really are pretty interesting. Once you remove the little yellow buds, a whole sea of seeds lies underneath. He spent a good fifteen minutes removing the seeds one by one with tweezers!

Exploring Corn


There's nothing like eating fresh corn on the cob. But before the yum-fest happens, let it be explored. Spend some time examining the ears of corn in their husks.

What does the husk feel like?
How can we find out what's inside?
What does the silk feel like?
Why do you think the corn is inside the husk and silk?
How does your family prepare corn?
Where do we get corn on the cob?
Have you eaten corn other ways?

Shuck the corn. Prepare the corn. Eat (and enjoy!) the corn.

Air Moves Things


Materials: Straws, feathers, pom poms, plastic bottles, pebbles, crumpled paper balls, any objects that might move with air.

Place objects on a flat surface and blow through a straw, aiming air at the objects to see which ones move and how much air it takes to move them.

*Extension
: Can you find 3 MORE things that air will move?

*Extension
: Have air races. Who can move the feather to the end of the room the fastest?

*Extension
: Go on a wind walk and observe all the things moving in the wind.

*Variation
: Use turkey basters or paper fans to move objects.

*Variation
: Create abstract paintings by dropping small amounts of paint on paper and blowing the paint around the paper with a straw.

Adopt a Tree


Meet my adopted tree, above. At first, I was a little hesitant to jump on this activity as a preschool activity, but I realize it's important to show children change over time. Select a tree nearby that you can observe throughout a year. It can be informal, as in talking about it each time you walk by. Or you can be formal "scientists" taking samples, collecting measurements, researching it, taking its picture, drawing it, and even getting crayon rubbings of the bark and leaves.

A fun book to read with this activity is The Giving Tree by Shel Silverstein, Harper & Row, 1964.

Mentos in Diet Coke; Cause and Effect


Parents: I recommend your supervision while doing
the following activities with preschoolers.

Here's how I spent 30 seconds of my last science and math class. Have a little fun with cause and effect and drop some mint Mentos into a rolled up paper tube and release into Diet Coke!

http://en.wikipedia.org/wiki/Diet_Coke_and_Mentos_eruption

*Variations: Explore the reaction of vinegar and baking soda. Or fill a film canister 1/3 full with water and drop in an Alka-Seltzer. Replace the lid and flip it over, setting it down on the lid. Wait for the POP as it blasts off!

Sun Prints

**Arrange a few interesting items on black construction paper and leave in the sun for about 1 hour. The sun will fade the paper leaving nice prints behind.**

Protect That Brain! Eggheads

This format is a bit different because I used it in my math & science class.

Materials: Eggs, newspaper, markers, scissors, tape, various materials to construct with (Examples: fabric, rubber bands, styrofoam, bubble wrap, egg cartons, cardboard, cotton balls, pipe cleaners, straws, anti-slip mat, etc.)

Objectives: Observing, comparing, and communicating. Discover why we wear helmets when we ride our wheeled toys.

Age Group: Preschool

Procedure: Your brain controls your entire body. You brain helps you move and think and learn! Our brains are soft and they are protected by our bony skull, just like the inside of an egg is protected by the shell.

Invite the children to draw faces on the eggs and create various helmets from the supplied materials to protect their “eggheads.”

Drop the eggs wearing the helmets from about waist height. If the eggs break while wearing the helmet you can ask “Was the helmet unsafe?”, “Did the egg fall at an angle so that it was not protected?”, “How would you make the best helmet?”

Scaling up: Challenge children to protect eggs dropped from a higher level.

Scaling down: Have a few egg-helmets ready made for trials. Or cut apart egg cartons for the helmets to eliminate the construction part.

Safety Concern: Raw egg can contain salmonella bacteria. Keep eggs cold until ready to use. Wash hands thoroughly! You could cook the eggs beforehand.

Grow an Animal


Dollar Tree has these neat little sponge-like critters that you can purchase that when you put them into water they grow and grow. The alligator works well for this activity.

To make this "educational" you check in on your animal daily for a week. With a simple measuring tape, measure the length and make a graph or chart to show its growth progress. You can also take pictures of the animal each day next to the measuring tape, print them, and challenge your child to sequence them.

There you have it, $1 math & science!

Roly-Poly Science


C is fascinated by these little guys and in just the time it takes to unload the car of groceries, he's gathered a handful. So playing from his curiousity, I came up with some questions to ask him about the bug that rolls into a ball and gave him a magnifyin glass to get a closer look.

Tell me what they look like?
What do you think roly-polys eat?
Tell me about your roly-poly.
How do they move?
Which end is the head and which is the tail? How can you tell?
Why do you think it curls up in a ball?
Can you tell me something else that is the same size as the roly-poly?

Want to know more? Read A Pill Bug's Life by John Himmelman, Children's Press, 2000.

Dissecting Flowers

Materials: Fresh flowers, magnifying lenses, tweezers

Purpose: To teach children about flowers and their various parts; and to let children explore flowers.

Procedure: Give child a flower to examine closely. An older child might learn scientific names for a few of the parts. A good chart can be found at: http://www.enchantedlearning.com/subjects/plants/printouts/floweranatomy.shtml

Younger children can compare, count, measure, feel, get a closer look.

Cautions: Allergies, some pollen may stain like on the anthers of a lily

*Extension: Grow your own garden. Sunflowers are a great example of plant life cycle because once grown, the seeds can be harvested to grow more.

*Extension: Press flowers or petals between wax paper sheets inside of a thick book to use for art projects.

Clean Mud

A wacky science/sensory recipe I did with the preschoolers today.

Materials:
1 bar Ivory soap
1 roll toilet paper
Popsicle sticks

Tear the toilet paper into shreds into a small tub or large bowl. Use popsicle sticks to grate the bar of soap into the toilet paper pieces. Add warm water a little at a time until mushy. Add water until the mixture sort of stops soaking it up. It gets an oatmeal consistency but the more you mix and mash it, the more the TP dissolves. Leave overnight for best results.

This is one of those ones that is hard to explain but neat to experience. Trust me on this one!

Dancing Garden

Use creative movement and guided imagery to introduce or review the concepts of plant growth.

1. Show the child some seeds. Talk about what seeds need to grow. All seeds store a little bit of food inside them to help the plant start to grow. Once the plant is in the sunlight, it can make much of its own food through photosynthesis.

2. Ask the child to become a seed, forming their body into the tiniest body shape they can create. What kind of seed are you? What plant will you become?

3. Lights off! Seeds grow underground in the dark. Explain that when they get food and water that they will grow in slow motion.

4. Give child a piece of fruit to eat to eat when it starts to rain.

5. A plant mister or spray bottle with water on mist becomes the rain. Encourage them to grow in slow motion, sprouting as they eat the food stored in the seed.

5. Turn on the lights. Now the seedlings don't need their stored food anymore. They soak up the sunlight and photosynthesize. Oh, but the plants can't make their own water so they might need a little more rain.

6. When the plants are grown, find out what each child is. What would happen with no sunlight? No rain? What do people need to grow?

WORDS YOU CAN USE: Seeds, plants, grow, nutrients, shape, slow motion, photosynthesis, rain, sun

Boat Loads


First, you'll need a small boat. You can use a toy boat, modeling clay, styrofoam or foil to create one. Float your boat and load it with small items, such as paper clips. Add a few at a time, watching the boat sink lower into the water. How much cargo will your boat carry before it sinks? Can you design a boat that will hold more cargo?

*Variation
: Design the tiniest boat you can that still floats.

*Variation: Create a boat with a sail and blow it across the water. Ask a friend to race his or her boat across the water with you.
