In space, astronauts don’t have gravity to keep them in place. That makes doing even simple tasks difficult. Gene Cernan was the first astronaut who worked on a task outside a spaceship. He said of the experience, “Every time I’d push or turn a valve, it would turn my entire body at zero gravity. I had nothing to hold on to.” As he worked, Gene Cernan’s heart rate and temperature went so high that his fellow astronauts worried that he wouldn’t survive.
Think about routine tasks that astronauts might need to do inside and outside a spaceship. Choose several tasks, and describe the features the ship and spacesuits should have to account for zero gravity as the astronaut completes the task. Use Newton’s laws of motion in your analysis.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
