In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity (p.6-10 of PDF), learners use different methods for hunting minibeasts (bugs). Learners can either make traps or simply look for minibeasts under stones and logs.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners determine whether thermal energy can be used for work.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners collect worms and then observe how they move.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners discover how solar energy can be used to heat water.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.
