Experiments do not have to be complex to be effective. In fact, simple fun experiments that can be repeated can created the biggest learning/have a huge impact. This is a science experiment that can be used k-12 to explore concepts of gravity, air resistance, and forces. It involved dropping items…yup…you just need some objects to drop. It is engaging and can help students understand how to make/record powerful observations. And did I mention, it is fun!
