In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

Combine math and exercise with this activity. Learners count how many times in a row they can skip rope or throw and catch a ball.

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

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

In this optics activity, learners conduct an experiment to find out why two eyes are better than one!

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 discover a brain process called habituation.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.
