Quick preschool science experiments?

Question

My son is hooked on science. I know the baking soda and vinegar one but I need a few others that are quick to do in the kitchen before dinner. Any ideas or sites I could use?

Thanks. Its for a almost 5 and almost3 year old boys.

...and there are so many more.  Also, you might want to go to the education section of your favorite bookstore or check on Amazon.com.

Answer 2

Oh ,to learn about the parts of plants and their parts, grab 2 cups of water and put food coloring in em. Then split a celery stick halfway the long way and place each end of it ion the water. After like 10 min, cut the slice the celry and yiu can see how the water transports through the "veins" and stem.

Another thing is to grab a cup of water, put pepper in it, and dab a bit of dishwashing soap on yur finger. Put it on the surface of the water and the pepper will spread apart and clear around your finger.

Answer 3

try putting a mentos (candy,any flavor) in a soda pop. (coke,pepsi,dr pepper)

Answer 4

I did one with celery, water & food coloring.  You put the cut end into the water with food coloring.  The color goes up the stalk into the leaves.  It is real faint, but it does work.

I did one with split peas too.  You fill a cup with the peas.  Then add water.  The cup is placed onto a cookie sheet.  When the peas fill up with water, the top ones spill out & make a *ting* noise on the cookie sheet.

Plus, you could get a book of experiments.  My company, Usborne Books at Home has some.  Go to:  http://www.books4haylea.com.  Search for experiments.  I got 44 results!  They have them with magnets, water, in the kitchen, lights & mirrors, etc.  Check them out!

Flubber or goop - The kids i work with LOVE this.

Show children how colors mix together maybe use food coloring

"dancing raisins"  - I havent tried this as of yet but i was told if you put raisins in a clear soda, it make then move around.

Mix water and cooking oil together in a clear soda bottle.

Here's another one I havent tried but looks interesting - 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 6

Dancing raisins (my kids love this!)  Place a few raisins in a glass of frshe (still really fizzy) Sprite or 7Up.  They appear to dance in the glass as the bubbles from the carbonation attach to the raisins and pull them to the top of the glass, then the "dive back down again - very fun    

Other fun things that you can do in the kitchen - let them make their own butter for dinner by placing heavy cream in a jar and letting them shake it until it turns to butter.  

Or for dessert - let them make ziplock bag icecream - half and half, sugar and vanilla in a quartsize ziplock.  Place this bag into a gallon size ziplock bag that is about 1/2 full of ice and salt.  Shake away - they will be delighted that the liquid froze into ice cream...especially if you don't tell them what the end product will be.

Use a glass to let them layer liquids of different density (oil, water, salt water.  Use a different food coloring for each liquid.  Let them try adding the liquids in different orders to see what happens.  

Give them a wintergreen lifesaver and a mirror.  Turn out the lights and have them chew with their mouth open while they look in the mirror.  The friction of tyour teeth against the wintergreen sugar crystals actually makes sparks.

Answer 7

You may want to look more up about this experiment and density, but you can mix water, honey, and oil and watch them separate. I think I have seen this done with food coloring added to the water.  Also maybe some things with floating and sinking.

Answer 8

Sprinkle salt and pepper on a plate and give them a plastic spoon. They will need to rub the spoon on their head and the static electricity will pick up the pepper only and not the salt.

Fill a baking dish with water and sprinkle in pepper in the center. Squirt soap in and watch what happens.

Fill a shallow pan with milk and food coloring and then a squirt of soap.

Answer 9

I know you have small children but i know an experiment. But its kind of dangerous. You get a bottle of diet cola and you drop in a mentos and watch it fly. Tip: you may want to stand back. I know it is dangerous but maybe when there older........................

Answer 10

This is the coolest. I don't know how to explain the science behind it. Sort of a science mystery to me LOL

Actually, I took a bit of time to google and here is the science behind it:

http://www.sciencebuddies.org/mentoring/...

"Colloidal" What a cool word! LOL

This project can be extremely messy. You may want to lay newspaper down on the floor or table before you start.

You will need:

Corn starch

Water

Shallow tub or bowl

Pour a small box of corn starch into the tub. Mix in small amounts of water. Then get your hands into the mess to get the full effect of this weird texture. The cornstarch and water mixture will harden in your hands when you squeeze it, but when you open your hands, it melts like goo.

Answer 11

Try to build a small 4x4 container so that when you drop it from a height, say 8 or 10 feet, an egg placed in the container won't break. Try to use creative, simple household items. I did this in school before and it was amazing what people came up with.

Answer 12

Mix 1 cup of Linit Liquid starch with 1 cup of Elmers glue.  It will start to combine and make a new substance.  Pull the blobs out and the children have made SLIME!  Fun to manipulate!

Answer 14

Wow!  That is awesome!  What a great way to build enthusiasm for science!

Here are some websites that might be of help.

I purchase a $4 insect catcher from Walmart and we have been collecting insects and looking for them on the internet to learn about them.  We taped some to a poster, but my daughter does not like to see them dead.  So I scratched the poster.  (smile)

The last website below seems to have more of what you are looking for.  Hope this helps and God bless you and those boys!

Answer 15

VINEGAR AND BAKING SODA THATS QUICK ENOUGH!
