In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity learners will be creating art using a traditional Japanese art style.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.
