Materials needed: Add PVC piping (elbows and straight pieces--these may be donated by your local home improvement store--ask! If you don't ask, the answer is always NO!), paper towel tubes (cut into various sizes), wrapping paper tubes and large marbles or small balls (like bouncy balls).
The children will not need any instruction! Just observe what they come up with while learning about physics and gravity with these materials!
Circle Time is such a great time for children to learn the social skills of being together as a large group AND to learn more about your theme!
Use your circle time for lots of discussion and for this theme, perhaps give them each "scientist" goggles to wear while learning at circle time!
It's a Mad, Mad....Swirl of Mad Preschool Science!
Materials needed: shallow bowl (lunch plate works well!), food coloring of different colors, dish soap and milk (go for whole milk..the fattier the better for this...anything 2 % or higher will work..NOT skim milk!)
Pour milk into the plate (about half full).
Tell the kids they are going to add food coloring. Ask what they think will happen. Accept answers.
Let each child choose a color and put one drop in!
Tell the children you are going to now add dish soap. Ask what they think will happen.
Be sure all the kids have a good view of the plate before doing this! It is so awesome!
Drop a few drops of dish soap and the middle and watch!
The colors spread in beautiful patterns. The soap creates a reaction to the fat in the milk.
Check the process out here!
Lava Lamps Thank you Jessica M.B for this activity!
Materials needed: clear, plastic water bottles with lids, vegetable oil, food coloring, water, Alka-Seltzer tables, flashlight,
Because you are using medicine (Alka-Seltzer), be sure to completely supervise this activity
1. Fill the bottle 3/4 full with vegetable oil.
2. Fill the rest of the bottle with water (almost to the top but not overflowing).
3. Add about 10 drops of food coloring. Be sure to make the water fairly dark in color. Notice that the food coloring only colors the water and not the oil. Hmmm...
4. Divide the Alka-Seltzer tablet into 8 pieces.
5. Drop one of the tiny pieces of Alka-Seltzer into the oil and water mixture. Watch what happens. When the bubbling stops, add another chunk of Alka-Seltzer. It’s just like a lava lamp!
6. If you want to make it even more "lava-like," put your bottle on a flashlight and turn the room lights off.
7. When you have used up all of the Alka-Seltzer and the bubbling has completely stopped, screw on the bottle cap.
Tip the bottle back and forth and watch a wave appear. The tiny droplets of liquid join together to make one big lava-like blob.
EXTENSION: Have materials to make one of these with each child at your science interest center.
Materials needed: raw eggs, hard boiled eggs, cups or bowls.
Crack open a raw egg into a cup. Talk about eggs with the children!
Peel a hard boiled egg and place in a cup. Talk about it with the children.
On a flat surface, spin a raw egg and a hard boiled egg at the same time.
Talk to the children about how they spin. Do they spin the same? Different?
What's happening: The raw egg has fluid that moves around when spinning. This makes the egg spin unevenly.
The hard boiled egg is now a solid and its contents are spread evenly so it can spin evenly and faster (insides are not moving!).
EXTENSION: Spin both eggs again and this time gently touch them to stop them from spinning and remove your finger. The raw egg will wiggle or wobble because the insides are still moving!
That's a STRONG egg!
Materials needed: raw eggs, big bucket!
PRACTICE THIS AT HOME FIRST!
Ask the kids if they think you can squish the egg in your hand!
Hold your hand over the bucket and hold an egg.
Close your fingers around the egg and squeeze as hard as you can...it should not break!
What's happening? The pressure you add to the egg is spread over the entire surface of the eggshell so it doesn't break, whereas cracking one just puts pressure in one area of the egg.
Snack Recipe Ideas for Your Mad Preschool Science Theme!
Cooking with children helps develop their math skills and helps them to learn how to follow directions. It also allows for some great conversation! Ask many questions while cooking with your children to encourage conversation! Be sure to ask specific themed questions while making these fun snacks!
Have the children help you cut the bananas into chunks. Keep the bananas peeled, just cut them!
Place them in the freezer.
Later in the day, or the next day, take them out of the freezer.
Have the children help peel the chunks. (This may take a few minutes...they are cold and the skins are stuck on! Perhaps let sit at room temp for a few minutes before they try to peel.
Add one teaspoon of water for every banana in the blender.
Blend and eat! The texture is just like ice cream! Really yummy!
Home Made Butter
Materials needed: small, glass jars (baby food jars), a pint of heavy whipping cream, pinch of salt, a stick of butter or small tub of butter (just to observe), plastic knife, crackers
I would suggest making this in small groups. It takes 4 or 5 minutes of shaking and most kids won't shake the jars that long or that hard on their own, but as a small group, they will do great!
Show the children the stick or tub of butter. Ask if they know what it is. Ask them where they think it comes from? What is it made of?
Have them help you pour some whipping cream into a glass jar. Add a pinch of salt for flavor. Cover tightly.
Tell them that cream is used to make butter and they are going to make some together!
Demonstrate shaking the jar, counting to 10.
Then pass it from child to child as they shake and count to 10.
Do this until the cream has turned thick! You will have to pour out the extra fluid.
Be sure to open the jar and look after you have shaken it for a while. If it is a clear jar, it will look watery because there is excess water that does not mix into the butter, but the rest will be a solid.
Mad Preschool Science Theme Ideas to Transform Your Dramatic Play Area
Mad Preschool Science Lab!
Turn your dramatic play area into a Science Lab. Have bins or tables available with these activities that are child directed--or add our own activities!
I HIGHLY recommend lab coats and plastic, safety goggles, just to make it official! (Adult, white button up shirts make great lab coats!).
Provide a flashlight. Take it apart so that the cover, body and batteries are on the table or in a bin. Let the children figure out how to put it back together so it works!
On a table, place black and dark blue paper. Provide large and small pieces of chalk and a shallow tray of water. The children draw with the wet chalk onto the paper. They watch as the water evaporates but the colors stay!
Rock and Roll!
Provide pipettes, water and a large selection of water. The children can sort, compare, observe the rocks as well as see how long it takes water to evaporate from rocks. The water also changes the color of rocks somewhat by making them appear darker when wet.
Provide magnifying glasses and paper (to use as journals) with crayons and a collection of some sort.
Ocean items--sea shells, starfish, seaweed.
Buttons--all sorts and sizes
Nope, not a cold place...but polar opposites! Magnets!
Provide many different types of magnets: horseshoe shaped, magnet wands, large button magnets, etc. Also provide a wide variety of items to investigate the magnets with: paper clips, magnetic letters and numbers, pencils, etc.
EXTENSION: In advance, make magnet bottles to investigate as well. Try filling a clear, plastic water bottle (1 liter) with salt and lots of magnetic items. Shake. The children use the magnet wand to "find" items in the jar by moving the wand on the outside of the bottle.
I have a 4 clock hour workshop available called "Science in the Preschool Classroom".

Mad Preschool Science Theme Activities to Help Your Preschoolers Develop Their Math Skills AND the Small Muscles in Their Hands!
Your OWN Silly Putty!
I used to LOVE this stuff, especially using it on the Sunday newspaper comic strips! Here's how to make some with your preschoolers!
Materials needed: Plastic eggs (for storage of course!), liquid starch, white glue, food coloring, cups, craft sticks to mix with, tablespoons
Children measure 2 tablespoons of glue into a cup.
They add 3 drops of food coloring into the glue and mix with the craft stick.
They measure 1 tablespoon of liquid starch into cup and mix.
Remove from cup and knead, mix with hands.
Store in plastic eggs.
This is a great manipulative to build up those muscles! Also, give them some newspapers to press the putty onto and when they remove it, they will see a mirror image of what they pressed it onto!
Make Your Own Crayons
Materials needed: muffin tins, crayon pieces (paper peeled off). Peeling the paper off the crayons is a GREAT small/fine motor activity for the kids to do! I recommend pre-slicing the outer paper with an exacto-type knife first to help the children get the paper peeling started. If not, they will become frustrated trying to get the peel started using their fingernails.
The children place the colors they want in one section of the muffin tin. Fill with crayon pieces to about 2/3 full.
Place in preheated 250 degree F oven for about 3-5 minutes, or until crayons are melted.
Remove from oven. Cool. Remove and use!
Mad Preschool Science Packing Peanut Sculptures
Did you know that most packing peanuts are now made of corn starch and water? This is because of prior choking hazards for children. You can test yours by dipping them in water...do they melt a bit? If not, they are plastic. Do not use these...they will not work!
You can purchase them in teacher supply stores or stores like Target (they can be purchased colored!).
Provide packing peanuts, shallow trays of water and cardboard or tag board.
The children dip the peanuts into the water and stick to other packing peanuts to make great sculptures!
If you are using white packing peanuts, have an activity on a different day where the kids color them with markers!
Show Me The Money!
Materials needed: Old pennies (dirty ones!), table salt, white vinegar, cups, spoons, baby wipes.
First, have your scientists clean their pennies using baby wipes. Ask questions: Are your pennies getting clean? Why or why not?
Then, each child puts about a 1/4 cup vinegar and 1 tablespoon of salt in a cup.
Stir for about 2 minutes.
Remove pennies. Now wipe clean with wipes! Wow! Shiny!
Mad Preschool Science Playdough CreaturesThank you Jessica M.B. for submitting this activity idea!
Materials needed: Playdough (preferably your favorite recipe that you make WITH the kids!), scraps of collage materials, toothpicks, craft sticks, etc.
The children make their own Mad Preschool Science bug, creature, monster, person, etc.
Mad Preschool Science Theme Music & Movement Activities to Get Your Preschoolers Movin' and Groovin'!
Sound Glasses--Just Musical but Mad Preschool Science!
Materials needed: 6-8 glasses (same size), water, food coloring, pencil or metal spoon
Have the children help pour different amounts of water in the glasses.
Add different colors of food coloring to each glass.
Demonstrate the different sounds each glass makes.
Let them play!
EXTENSION: Suggest "patterns" for the children to play: Red glass, red glass, green glass, red glass, red glass, green glass!
EXTENSION: I am by NO stretch of the imagination musical! I actually encourage the children to sing louder than me to drown me out because, well, NOBODY wants to hear me sing! ;) But, I digress! If you, or someone you know IS musical, ask them to help measure enough water in each glass so that it represents an actual musical note and then play some songs!
Everyday Musical Instruments
Provide a variety of everyday objects that can be made into instruments by your scientists. Suggestions:
Tin pie plates, blocks of different colors and sizes, metal cans (with the edges taped for safety), wooden and metal spoons, pots and pans, boxes, pencils (to use for drum sticks), coffee cans with covers, etc.
Don't tell your kids how to use them.......they already know!
Bubble Wrap Dancing
Materials needed: lots of bubble wrap, CD player with fun music
Before dancing, sit with the children and give them each a piece of bubble wrap. Yes, they will pop them...of course! Join in the fun. Ask them what they think makes the noises? What are in the bubbles? Etc.
Then, let the children dance like mad on the bubble wrap while the music plays!
EXTENSION: Play freeze dance! They need to freeze...like a frozen bubble...when the music stops and not dance again until the music starts.
EXTENSION: Have a variety of tempos of music to dance to--fast, slow (jazz, rock, etc.).
Mad Preschool Science Musical Egg Investigating and Making!
Materials needed: An actual music egg, Plastic eggs, clear packing tape, variety of seeds, beans, rice, jingle bells, paper clips, etc.
Let the children check out the music egg. Ask them to discuss what it is made of, what is in it, etc.
Now, tell them they are going to make their own.
Provide the materials in different bowls.
Let the kids investigate the types of sounds each item makes in a plastic egg of their own.
Let them try adding several items to their egg!
When they are satisfied with the sound of their egg--tape them up with clear packing tape, write their name (using a permanent marker) and dance away!
Use the eggs to identify colors, counting, following directions etc:
Kids LOVE this and they can make it themselves, if you would let them!
You add 3/4 cups of cornstarch with 1/2 cup of water (you can add food coloring to the water before adding to the cornstarch. It is difficult to add color once it is mixed).
It is stiff in the bin, the pressure from holding it “melts” the mixture and it drips off and through their fingers! (The corn starch and water combination is a suspension--a non-Newtonian fluid--the texture/viscosity changes with force!
Try having different bins of different colors of goop!
Have the children measure 1 cups of plaster of Paris and 1/2 cup water into their baggies.
Help them seal it quickly.
They knead the bags until mixed (remember, it sets pretty quickly).
Let bag sit once mixed.
When dry, remove from bag and let children paint their sculptures!
Yikes! Yeast Gas!
This is an experiment I have not yet tried, but was told is pretty cool (it was done in a Kindergarten classroom).
Materials needed: small bottle with skinny neck (like a glass soda bottle), balloon, package of yeast, 1 tablespoon of sugar, warm water
Put the sugar in the bottle (let children see, touch, smell the sugar. Talk about what it is used for and other information they might know about sugar!).
Pour warm water into the bottle so that it is about 1/3 full.
Put the package of dry yeast into the bottle and mix it up.
Stretch the opening of the balloon over the opening of the bottle.
Observe! The gas created by the yeast and sugar mixing will inflate the balloon...it takes about an hour so watch it over time.
Perhaps take a classroom observational check on it every 5-10 minutes and write down what the children observe!
Crazy and Mad Preschool Science Ice Balloons
Fill balloons with water and put in freezer.
Remove from freezer and peel balloons off.
Provide food coloring and pipettes to the kids to drip onto the balloons.
Leave in the bins and watch them throughout the day as they melt and the colors mix even more!
The best way to do this is to sprinkle some rock salt on the ice. This will melt the ice a bit and when the kids start dripping the colors on them, the colors will go on the outside and the inside of the sculptures!
There is a picture of this on my Pinterest Page under Mad Science Theme. See the Pinterest Link at the bottom of this page.
Mad Preschool Science Musical Peas
This is GREAT!
Materials needed: Wine glass (yes, a glass one!), a bag of dried peas, a metal cookie sheet
Place the wine glass on the cookie sheet.
Fill glass to the top with dried peas.
Now, fill the glass slowly with water, to the brim.
Just observe and listen for the change over the next hour or so. YOU will need to add water as the peas absorb the water over the next hour.
The peas will absorb the water and expand and will begin overflowing the glass!
SpEGGtacular Mad Preschool Science Time!
Have you ever made a rubber egg? This is fun to observe!
Place a raw egg into a clear jar. Fill jar with vinegar so that you cover the egg with it.
Let sit in jar. This can take from 24 to 48 hours to complete, so it is an "observational" activity!
Remove the egg and check it out!
The vinegar will almost immediately begin to break down the shell. Over the next day or so, it will dissolve the entire shell but the membrane of the egg keeps the insides intact an pretty rubbery!
VARIATION: I have never tried this, but was told that if you rub fluoride toothpaste on the egg before placing it int he vinegar, the shell won't dissolve! So, perhaps you could experiment with this and let me know if this is true!
Perhaps have 3 eggs: One in vinegar, one half coated with fluoride toothpaste and the third egg completely coated with fluoride toothpaste!
Miscellaneous Activities for Your Mad Preschool Science Theme!
Mentos GeyserThank you again to Jessica M.B. for submitting this activity!
With this project you can test out different sodas and brands if you like or just stick with one. I used diet coke. There are two ways you can do this. They sell a tool that you put the candy in and hook it to the soda bottle and has a release sting to pull then the candy falls in the bottle. And the magic happens. Or if you want to get messy you can put the candy in yourself but get ready for a soda shower.
Materials needed: Mentos, soda, And the tool if you wanted to get it cheap on eBay!
The science behind this is:
As you probably know, soda pop is basically sugar (or diet sweetener), flavoring, water, and preservatives. The thing that makes soda bubbly is invisible carbon dioxide gas, which is pumped into bottles at the bottling factory using tons of pressure. Until you open the bottle and pour a glass of soda, the gas mostly stays suspended in the liquid and cannot expand to form more bubbles, which gases naturally do.
But there's more... If you shake the bottle and then open it, the gas is released from the protective hold of the water molecules and escapes with a whoosh, taking some of the soda along with it. What other ways can you cause the gas to escape? Just drop something into a glass of soda and notice how bubbles immediately form on the surface of the object. For example, adding salt to soda causes it to foam up because thousands of little bubbles form on the surface of each grain of salt. Many scientists, including Lee Marek, claim that the Mentos phenomenon is a physical reaction, not a chemical one.
Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. In order to form a new bubble, or even to expand a bubble that has already formed, water molecules must push away from each other. It takes extra energy to break this "surface tension." In other words, water "resists" the expansion of bubbles in the soda.
When you drop the Mentos into the soda, the gelatin and gum Arabic from the dissolving candy break the surface tension. This disrupts the water mesh, so that it takes less work to expand and form new bubbles. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form.
As soon as the Mentos hit the soda, bubbles form all over the surface of the candy. Couple this with the fact that the Mentos candies are heavy and sink to the bottom of the bottle and you've got a double-whammy. When all this gas is released, it literally pushes all of the liquid up and out of the bottle in an incredible soda blast. You can see a similar effect when potatoes or pasta are lowered into a pot of boiling water. The water will sometimes boil over because organic materials that leach out of the cooking potatoes or pasta disrupt the tight mesh of water molecules at the surface of the water, making it easier for bubbles and foam to frm. When a scoop of ice cream is added to root beer, the float foams over for essentially the same reason. The surface tension of the root beer is lowered by gums and proteins from the melting ice cream, and the CO2 bubbles expand and release easily, creating a beautiful foam on top.
