How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates. 

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...
