Use this hands-on activity to demonstrate infrared and thermal radiation.

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.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners investigate the effect of heat on a reaction.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity (posted on April 18, 2011), learners follow the steps to construct a zoetrope, a device that produces an illusion of action from a rapid succession of static pictures, using a 16" bik

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
