What are 5 testable questions for high school?

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!

• 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?
