Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.

In this math activity, learners practice comparing fractions.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

This activity is an investigation of static electricity. What happens when you get "static cling?" Basically, you pile up electrons on one thing, which attracts the protons in something else.

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

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

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

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

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

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this math game, learners throw dice and place the numbers in one of four boxes. Learners repeat this three more times and the learner with the largest four digit numbers is the winner.
