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

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 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 investigate color vision as well as plan and conduct their own experiments.

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 act as epidemiologists by mapping the prevalence of HIV/AIDS worldwide.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

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

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.
