In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

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

In this activity, learners discover if carbon dioxide has an effect on temperature.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

"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 engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this project, students explore how levers work, by making a puppet with moving limbs.

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.

Learners construct a rocket from a balloon propelled along a guide string.

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

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

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t
