DIVING DOWN DEEP (TI-Nspire™)
 
Chemistry

Key Topic: Gas Laws

The Neutral Buoyancy Laboratory (NBL) is a large pool where diving sessions allow astronauts an atmosphere resembling zero gravity (weightlessness) in order to train for missions involving spacewalks. Other divers assist the astronauts during their spacewalk practice. In this activity, students will learn more about what is involved in a dive session at the NBL. They will explore a method for adding air to a gas cylinder and determine that amount of gas needed by a diver during one session.

Students will
  • explore and apply gas laws;
  • add pressure to a bottle and determine the moles of gas added using the ideal gas law;
  • create and interpret a mathematical model as it relates to the experiment performed; and
  • relate findings from the experiment to a real-world situation.
