In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners will experiment with different materials that can melt and change ice.

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

This is an activity about friction as well as kinetic and potential energy.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
