In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this activity about depth perception, learners create an optical illusion in a shoe box.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.

In this activity about endoskeletons (page 8 of PDF), learners observe, compare and contrast different kinds of chicken bones, and relate their chicken bone observations to human bones.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
