What is the best 8th grade science project ever?

We think the Extracting DNA from Onions science fair project is awesome for middle school students! This science project aims to demystify DNA by showing how easy it is to extract from onions and what DNA looks like when it's outside of the cell. It's a classic science experiment to learn about DNA and how DNA can be extracted from many kinds of cells. Check out the video on the project page where DNA is extracted from strawberries too! What other fruits and vegetables can you extract DNA from?

What are 5 testable questions for 8th grade?

A testable question is a question that we can answer through a science experiment. To do this, we do a control science experiment, then we change one thing in the experiment to see how it affects what happens. This is how we can discover the answer to our question! Eighth grade science students can use the following testable questions for a science fair project.

Do detergents affect plant growth?

Can drink and food taste different just by changing its color?

Does the color of light affect photosynthesis?

Does temperature affect seed sprouting?

What makes popcorn pop?
