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.

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.

Students create a scale model of the solar system using beads and string.
