Quick Science Experiments for Kids

Watch this free 90-second episode and use the instructions to create your own science experiments in the classroom or at home. 

Milk Soap Rainbow | Grades K–12

Explain It: How does soap change the properties of milk?

Time: 15 minutes

Using milk, food coloring, and dish soap, students experiment with surface tension and chemical change. This lesson is a great way to teach states of matter, properties of matter, attractive forces, and surface tension.  


Water Sketching | Grades K–12

Explain It: How can you draw on the surface of a liquid?

Time: 15–20 minutes 

Using dry erase markers, glass, and water, students experiment with the properties of cohesion and adhesion. This quick, hands-on science experiment is a great way for students to explore the properties of matter and, for older grades, capillary action.
