In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity (pages 26-29 of the PDF), learners investigate how they can develop super memories by using mnemonic devices.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

In this activity, learners will explore how the human brain interprets environmental stimuli.
