Quickly and easily model how colors reflect, absorb, and interact with each other in the classroom or online using your computer’s camera.

In this lesson, students build a paper helicopter, then improve the design and compare and measure performance.

Students use satellite data to help determine the greatest renewable energy potentials in any given region and develop graphing skills.

Students modify a paper cup so it can zip down a line and drop a marble onto a target

Students learn about surface features on Mars, then use a visual programming language to create a Mars exploration game.

Students build a rubber-band-powered rover that can scramble across the room.

In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

Students will compute the approximate travel time to planets in the solar system using different modes of transportation.
