STEM on Station -- Science

Filmstrip with various science images


The International Space Station is the ultimate science laboratory! Experiments and demonstrations are practically free from the effects of gravity. How are physical phenomena affected by microgravity? Here you can view videos of astronauts aboard the space station as they demonstrate science concepts taught in grades 5-12. Show students a real-world demonstration of Newton's Laws, and explore pendulum motion and other science concepts in the microgravity environment of the space station.

Mass vs. Weight Educator Guide -- Students often confuse the terms "mass" and "weight." Each activity in this series demonstrates the difference between mass and weight by comparing students' results with the results of astronauts aboard the space station.

A Breath of Fresh Air Lab Activity -- In this lab activity, students learn about the electrolysis process that is used on the space station to produce oxygen, and then they perform their own electrolysis.

Oxygen Generator System -- Students learn how the OGS produces breathable oxygen for the crew by converting wastewater from the space station into oxygen and hydrogen through the process of electrolysis.

ARED -- Resistive Exercise in Space -- In this activity, students analyze different aspects of the mechanics of the Advanced Resistive Exercise Device.
