In this activity, learners explore how to protect their skin while applying pesticides to plants.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

Learners discover how important their thumbs are by attempting various tasks without them. After tying up their thumbs, learners attempt to legibly write their names or play catch with a tennis ball.
