In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

Can gelatin (like Jell-O ®) change the speed of light?

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

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.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

In this activity, learners create their own weather forecast map.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners identify different classes of matter based on physical properties.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
