Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.
