This is a guide about blowing up a balloon with baking soda and vinegar. The chemical reaction that takes place when you mix baking soda and vinegar can be used to blow up a balloon.
This is a guide about watermelon dry ice explosion. Try this fun science experiment with your older children. It is sure to be a hit.
Place a lump of coal in bowl and sprinkle 1 Tbsp. salt over the coal. Carefully pour 2 Tbsp. water over salt. In the same manner, pour 2 Tbsp. of laundry bluing. Then add 2 or 3 drops of mercurochrome. Repeat with food coloring. After several days, you should have a colorful mosslike growth. If not, add a few more drops of water. This is something small children really enjoy!

Preschoolers love to watch things grow. Take a zip type storage or freezer bag, put a moist paper towel inside and place a couple of the large lima beans in with the towel, Seal it and tape to a window or on a wall where the sun will shine on it. Watch it root.

Place a moist paper towel in a zipper freezer bag with a few lima beans. seal it and place in a window or hang on a wall where the sun shines in and in a few days time it will begin to sprout.
Colored water in a clear glass conrainer with cut flowers (white or yellow work best) ... In a day or two they will start to streak with the colored water. Little kids love it!
Mine loved some of these hope they help:
Grow hair, have the parents send an egg to school, chip off some of the top fill with soil sprinkle with grass seed and place in egg carton that the top has been removed from have the kids put a face on the egg and wait the for the hair to grow.
Here are a couple of places for more ideas. Have fun:)
One spring, we borrowed an old science fair project that was a chick incubator, got a dozen fertile eggs, and every day, took those eggs into our bathroom, without a window, turned out the lights, and "candled" the eggs, by shining a flashlight on the bottom of the eggs. For the first couple of weeks (chicks take 21 days) you can watch the developement of the circulatory system and then the first forming of the chick. After that, it is just a dark spot as the chick grows. We did this for our three little ones, and several of the preschoolers in the neighborhood who came every day to see the progress. We had half of the chicks hatch, and on that day, one or the other of the neighborhood children got to see the actual hatching of a chick. It must have really made SOME impact on us, because we moved to the country, and guess what our favorite pets are.....chickens!
Get an empty metal gas can if you can find one, warm it up with 1/4" boiling water in it so they can see steam emerging, then let it cool with the cap on tight, and they will be impressed watching the vacuum inside crush the can completely within like 20 minutes. I never forgot that one.
http://www.mainstreetmom.com/ might have some ideas for you. It's a website filled with all kinds of links. You might also find info on the PDE website, the Pennsylvania Department of Education.
Grow a Carrot Forest
Cut the tops off some carrots (unpeeled)
Place a tissue folded, onto a saucer or plate
Wet the tissue
(note** tissue should be watered daily & kept
moist at all times)
Place the carrot tops on to the tissue
Put the saucer in a sunny window and
In a week or so, you'll have started to sprout
your very own carrot forest.
You can keep this project going for quite a while as long as you keep the tissue wet.
Place an assorted variety of grapes on a plate in a sunny window, and within a week or two you will see how they turn into raisins.
Gooy Cornstarch Fun
Mix up a cup of cornstarch with a cup of water and some food colouring. Blend together well and pour into a shallow container. Let the Kids see how it settles into a "solid", but when they squish it with their hands, it becomes "liquid"....this is a fun project and an easy clean up.
You could do some experiments with magnets. Have them go around discovering what else besides the fridge that magnets will stick to. Also they could do a search to see where there are magnets in the house -- ie frigde seal, cupboard latches, many toys, etc. Be sure they don't put the magnets on the tv screen or computer monitor. Magnets can also damage video and audio tapes, but it usually takes a very strong magnet.
Static electricity is nifty to experiment with. Rub a balloon on your hair, and stick the balloon to the wall. Create static on a nylon comb and then attract or repell little styrofoam balls or bits of paper. A nifty trick is to stick the paper sleeve from a plastic straw to the wall after you remove it from the straw.
You could make a "volcano" with baking soda and vinegar. Or you can put some vinegar in a pop bottle -- say 1/4 cup-- and a couple tablespoons of baking soda into a balloon. Pull the top of the balloon over the top of the bottle and the baking soda will fall into the vinegar. Shake or swirl it abit to dissolve the baking soda, and the balloon will "blow itself up" as the baking soda neutralizes in the vinegar and creates carbon dioxide.
Cooking is good science for kids too. Bake something with regular yeast, so the kids can see the yeast grow in the sugar and water solution. They can smell the yeast to find out that it is giving off gas, which is what will cause their bread to rise that they will bake with you!!! Growing yeast will also blow up a balloon, but it takes a little bit longer than the baking soda and vinegar.

I remember in first grade growing bean seeds in little milk cartons. It was so fun watering and watching the beans grow. We got to take them home when they got big enough.
Freeze water in large containers. When solid, pop out of the container. Tint table salt with liquid water colors and dry thoroughly. Let kids sprinkle the colored salt on to the ice. The salt creates holes and the color allows the kids to see the melting process. You will definitely hear OOOHs and AHHHS!
If you live in an area with white flowers like Queen Anne's Lace you can demonstrate osmosis by putting them in colored water.
I'd be careful to give pre-schoolers anything but BIG magnets that they can't swallow.
We like to take cornstarch and water add food coloring to it and it become ooblick. My boys have had hours of fun playing with their dinosaurs in it.
Adopt a Manatee. Go to www.savethemanatee.org. They will send you a list and a description of the manatees that need to be adopted. The manatees are usually ones that were injured by blades from boats. Then you pick one and for a small fee they will send you a birth certificate and a picture of your new family member.

Cut open a diaper and pull out the fluffy stuff mix with water and you have diaper slime, its messy but kids love that and one diaper makes a ton!
I am looking for some good Science Fair project ideas.
Not knowing your age or your mechanical ability this could be challenging. You can go chemical and build a volcano and use chemicals to make it explode. You can go electronic and make a crystal radio.
If your a programmer you can write a program that takes a set of numbers and gives you the character set equivalent I.E. here is a random phone number 626-8147 it could spell.

hmmm... doesn't spell anything, bad example but still a good idea.
You could make and explain a water clock.
You could make and explain a fulcrum and give examples of how fulcrums are used today.
Give me more details about you and the science fair and I can probably come up with a lot more ideas. I time period would help too.
Ooo. I just had a fun idea. If you are into military tactics you could build an example of the Roman Phalanx and write up how affective it was in combat situations for the Roman empire. Not purely science but there is science in it. If you want to see how effective it was watch the movie 300.
When I was in high school, these were my science fair projects.
One year, I showed how different chemical solutions would burn different colors in a flame. For example, a copper solution makes the flame green whereas another one (which I have long forgotten now) would turn it red or purple.
The next year, I created a hologram, using a laser and a sandbox on innertubes. That was pretty neat! I'm sure I got the plans and the supplies from my teacher in both instances.
If you are stuck, I would talk to your science teacher and see what he/she suggests. It would also be helpful to know what sort of science you are interested in: physics, biology, chemistry, etc.
I am not sure what age group you are taliking about. I saw a fun one at my daughter's school. This girl had used coffee filters and a vaccum hose to prove there is little difference between high and low nicotine cigarettes. The girl wanted to get her dad to quit smoking. Just an idea. :)
This may or may not be too low-tech for you, but should be okay whatever your age group, provided you're a month or so from your science fair. As I recall, most science fairs are in February or March, but that's been awhile ago; my youngest kid is 21.
How about planting two identical seeds in two identical pots. Put one in a sunny place and the other in the closet, cabinet, or other dark place. Otherwise, treat them the same (same amounts of water, fertilizer or plant food.) Notate the difference and explain why there were different results with the two plants.
Thanks for all the great ideas. Hope I can come up with something and I'm 17.
I am looking for a website that has quality, low cost (or free using stuff at home) easy science projects and/or experiments for a first or second grader. Any recommendations? Thanks.
Is there a way to make a really cool thing to demonstrate how bread rises?
