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 investigate the properties of different types of balls.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

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

In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

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

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

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 an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

This activity is designed to let learners measure their reaction time or response time to something they see.
