In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

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

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

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

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

Learners build a wind turbine and test it to see how much energy is created.

In this activity, learners take apart a used zinc-carbon dry cell battery.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.
