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. Students perform the activities and analyze their data. Then they watch video of astronauts performing similar demonstrations on the station. The activities focus on Newton's second law of motion.

As they complete these activities, students will do the following:

  • Demonstrate the difference between mass and weight.
  • Investigate careers in space exploration.
  • Learn about the international partnerships involved in the space station.
