plant project

I think I'll do the crystal growing project for my 7th grade project, and the best project I've done was the "compare how fast plants grow depending on the amount of iron in the soil" project, but someone who sent shrimp through tubes won, is that even a project?
—Guest trey b.


maybe you can do: what type of fertilizer helps plants grow the best? organic vs. chemical.

First off to say, never do the Volcano experiment or the mentos with soda. (: Also I like the video game one and the Diaper one. Also, I need help with a good 7th grade idea.
—Guest Breeze


you shouldn't do the experiment to see what diaper holds the most....water! It has been repeated way TOO MANY times! And people aren't going to care how much the diaper holds, they won't be leaving their babies in the diaper until the diaper holds as much as it can, the judges want to see something they would actually care about and use, trust me it isn't smart!

SMile : Now you see , NOw you don't

JUst because smiles arent appealing ( at times) doesnt mean, there fake. A smile is a Smile _ so to make a long story short try this project : Can you tell the difference between a real smile from a fake one!!!!

I tried the volcano and I got last place because it wasn't original and a bunch of other people did it but the one that got first place was a huge magnet that stuck to a huge can of sprite

Which absorb more? Pull- ups' or diapers

I think someone should do this project because it is a 8th-12th grade science project.and all you have to do is do the rest by your self..

Teeth Trauma

Use old baby teeth or go to your dentist and ask for a couple. Take the teeth and let them sit in different liquids such as soda and orange juice. it's easy and you don't have to do much. I got 1st place in sixth grade and i also got a trophy over all the science fair projects. Hope you enjoy it!

temperature makes all the difference

et a crystal growing kit grow 5 of the same kind and put them in 5 different temps. and see if that effects them growing i did that in 6th grade and measure in centemeters
—Guest sidney


I am in 6th grade and I seriously need a project idea! I am maybe interested in doing something like: Does hand sanitizer really affect the amount a germs on your hands? If so, which hand sanitizer works the best? But if I did do something like that I don't know where I can find a procedure to do that! Please HELP!

Baking soda or Baking powder?

if you make pancakes, muffins, or any other simple recipe that takes either baking soda or baking powder, bake using the opposite (if it says baking soda, use baking powder, if it uses baking powder, use baking soda) make the recipe twice, one time using baking powder, and the other time using baking soda.
