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 astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity, learners explore their eye pupils and how they change.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

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 use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

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 online activity, learners find out whether they are smart enough to survive as a plant.

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 explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity, learners play bingo to learn about the diversity of birds. This game includes a warm-up lesson and "Full Flight" version.

In this online activity, learners measure their pulse rates and investigate how their pulses change when they engage in different activities.

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 online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

Learners work together as a group to learn a new physical activity. After working for a few rotations, learners time themselves as part of a contest.

In this activity (on page 2 of the PDF under GPS: Cactus Activity), learners will develop their own version of a tool used by biologists, a dichotomous key, by collecting all their left shoes.

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