In this activity, learners investigate the properties of different types of balls.

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 (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

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

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.

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

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.

In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

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 activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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.
