Answer 8

Is this the 6th grade science fair or 8th grade science fair?
For my 6th grade science fair, I did experiments on whether different colored light outputted different energy levels.
(Green had the highest output, at least for my testing it did...)

For my 8th grade science fair, I tested whether extra virgin olive oil has any benefits to cooking that regular olive oil.
(Extra virgin olive oil, has a higher burn temperature as well as provides more flavor, do to the smoke, when warming it past it's burn temperature).

I didn't win a medal, or anything....

Best of luck.

Answer 9

Answer 12

I still say bread mold. You learn a lot of things with that experiment and it is fairly easy.
A bit if molecular biology and genetics, both of which are complex topics for elementary school, but can be explained by simply letting a bread mold and then placing a moldy bread with another good mold and seeing how the bacteria interacts with the other bread.

Answer 13

ok you have 2 eggs and one cup of salt water and the other fresh water put the eggs in not cracked and see what happens

Answer 14

For my sixth grade science fair I got 4-6 different soaps and PH strips to test the acid in them to see which one damages you more and then for my eighth grade project I put water in clear plastic cups that I wrapped in different color construction paper (red,black,white, green, blue, etc) and put it outside for a few hours to see which color would make the water heat up more. There both simple projects, honestly. I won a ribbon for both, if that helps.
