In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.
