In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

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.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.
