In this free science fair project idea, we learn about surface tension and how it can support mass—in this case, a floating paper clip.

This project examines whether playing music during class helps students learn or if it distracts students from learning.

Checkerboard play challenges students to use spatial reasoning and computational thinking.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

In this project students experiment with making music using only glasses of water.

This science project allows students to study the psychology of happiness.

This science fair project teaches students about wilting and browning of salad greens.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.
