Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this activity, learners create models of bugs. Learners use household materials like plastic cups and straws to create models of bugs like centipedes and spiders.

In this hands-on art activity, learners will study and identify features of the external anatomy of a fish.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

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 play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this activity, learners will learn about proprioception, or the body's sense of its place and position in space.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
