Need ideas for a simple science project for kids

[TechBoyJK]

I need 3 ideas.

I have one, which would be a simple litmus test for OJ and vitamin c levels.

it can't involve humans or animals.

needs to be simple for k-6 grade.

Anything will do. cause its due tomorrow.

Coke and dirty coins?

Effects of smoking on plant growth. Or effects of lighting on plant growth.

I used the second one as my 7th grade science fair project and won 1st place in the district.

You can make Volcanos using vinegar and baking soda

 

[Ricemarine]

-Testing basic items for acidity (pH)
-Make rockets

awesome guys, keep it coming

Effects of water amount on baked food product quality. Amazing what a difference even 1 pound of water can make. Of course most people wouldn't know the difference, but working in the baking industry it is a big deal.

Have the students test the decomposibility of different common products waste. Items such as candy wrappers, food waste, etc.

 

[imported_Tick]

Test fermentation rates for differnet suger-water solutions at different temperatures with different Ph's.

The effect a .5" square piece of Magnesium has in a quart of water in a sealed container.

 

[StevenYoo]

measuring the amount of ascorbic acid (vitamin C) in common beverages by using the bottle + balloon + baking soda thing.

whichever beverage makes the balloon inflate more = more vitamin C

(not counting citric acid and stuff, but you don't have to mention that)

then you cross-reference by checking the nutritional labels for Vit C content

awesome ideas...... better results than I expected.

I'm thinking he means either phosphorus or sodium.

No you won't.

Oh hell, I don't remember. HS Chemistry was...eons ago.

Just kidding, BTW. This is a science project for kids...do the volcano thing w/the vinegar and baking soda. That always goes over well.

I blew myself up in HS...I threw some random solid into a beaker of boiling water; it was ugly.

Agreed. Magnesium blocks are atmosphericaly stable. And besides, magnesium doesn't burn all that hot. Aluminum is way better.

cups and string?

Of course burning magnesium is fun.

True. You know what else is fun? Thermite.
