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 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.

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.

In this activity, students use spreadsheet software and their knowledge of scale, proportion and ratios to develop a solar system model that fits on a playground.

Students model the position of the planets around the Sun and then model viewing them from Earth on any given date.
