## STEM on Station -- Mathematics

Science, technology and engineering all involve some degree of mathematics. This is true regarding the International Space Station and its microgravity environment. The orbit of the space station, the amount of storage space on the station, and the scale modeling used to design station components all engage mathematical concepts. See how mathematics applies to the science and engineering projects related to the space station.

**Earth, Moon and Mars Balloons** -- Construct a scale model of the Earth-moon-Mars system by planetary size. Then discover how far one might have to travel to get to the moon or Mars.

**How Much Is Waste?** -- Measure the mass and volume of a food package before and after repackaging for spaceflight; determine the usable and waste portions of food selected for spaceflight.

**Exercising in Space** -- Students identify a direct variation, solve linear equations, and create tables based on the exercise equipment provided for astronauts on long-duration missions on the International Space Station. The equipment helps the astronauts maintain their fitness to perform mission objectives and to return to Earth without serious health complications.
