In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners explore the different heating properties of soil and water.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
