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

Using the fundamental criteria for life, students examine simulated extraterrestrial soil samples for signs of life.

Students use tangrams to create rover designs while practicing shape recognition.

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

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

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

Students will design, build and test a crew exploration vehicle, or CEV, to carry astronauts to Mars – meeting size, mass and payload requirements.

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

In this board-game lesson, students learn basic computer programming skills by playing the roles of a Mars rover, scientist and engineer to make exploration decisions and accomplish science goals.
