Question

Looking for fun science projects or experiments for my preschool class....ideas?

Answer 1

heres a few

Raisin Rising

Pour clear carbonated soda water into a clear glass. Drop four or five raisins into the glass.Show children how the air bubbles make the raisins rise and fall

Run Away Pepper

A great science demonstration. Sprinkle pepper over the top of a cup of water. Put a dab of soap on your finger and touch the center of the pepper. Show children how the soap repels the pepper to the side of the glass.

Sun Painting

Place various shaped flat objects on a dark piece of construction paper. You can cut out shapes and designs or use common objects like a ruler or key. Place paper in direct sunlight for a few hours. Show children how the sunlight faded the paper, leaving dark silhouettes.

Popcorn Dance

Fill small a glass jar 3/4 full of water. Mix in 2 tablespoons of baking soda and mix well. Add a drop or two of food coloring and 10 to 15 popcorn kernels. Then add a few drops of vinegar. The kernels will start to move in one or two minutes.

Answer 2

Cornstarch goop is really cool, there is two different textures to this and they have fun playing in it.

Frozen ice and salt... what happens?

Use primary colors of paint and let them mix the colors to see what they can make.

Not sure if you can do this but every year I get a tadpole for my class and watch it go from tadpole to frog.

Have them make playdough and talk about how it goes from liquid to solid by adding ingredients.  

Water and oil, talk about why they separate.

'

Sink or float experiment.

Plant flowers or vegetables.  

5 senses with food, so they can taste.

Answer 3

drop a mentos in a 2 liter of coke and see what happens kids love that one.

Answer 4

The Mailbox Magazines (check your local library...they sometimes have them you can check out) have a science experiment in every publication with the visual directions and all.  :-)  Perfect for preschoolers

Chemical Reaction...similar to volcanoes but provide various mixtures to explore with.  Make sure one of the powders is baking soda and the other is vinegar...I think lemon juice works too.

Color mixing...there are so many ways to do this.  One of my favorites is this...very simple. I provide eye droppers and an icecube tray with three slots partially filled with red, yellow, and blue water.  They can mix the colors in the other slots.  The younger ones always turn it brown so I usually incorporate "art" with it and provide coffee filters (the cone shaped ones make great butterflies).  When they drip their water onto the coffee filter the color "spreads"...so even if they have made brown water... they will see all of their colors on their coffee filter.  2 science experiments in 1!

Another fun color mixing is to place two different color paints inside of a quart freezer bag and reinforce with packing tape.  They can manipulate the bag to mix the colors.  Cute with a pumpkin theme.  I use permanent marker to create a jack o lanter face on the bag.  Then add red and yellow paint in two different spots...they mix it to make an orange pumpkin!

Thumbprint exploration is pretty simple to do...great with the Me, Myself and I theme... be sure to have pictures of the basic "spirals".

Sink and float experiments

Magnets

Weight... provide different materials and use straws to try and blow them.  Have them predict first.

Water absorption...I've done this with the color mixing experiement.  I provided different types of "paper".  We discussed which ones soaked up the water the best.

Overflow!  Usually I just add this to the water table... containers with items to place inside and watch the change in water level.  Also can be done with older preK students...eyedroppers and pennies.  How many drops until the water overflows.

Good luck!

Answer 5

magnets and how the repell and attract

Answer 6

depending on the age of the preschoolers it is fun to bubble paint, you use bubbles, food color. straws, and plain paper.

use the straws to blow colored bubbles at the paper. when the bubbles break they "paint" the paper.

Answer 7

U can alwayz do the icecream making science project. Search it!
