In other Title: Living In Space ways, it is quite different. in orbit above Earth must do the same things inside Length: 10:00 their spacecraft to live as we do on Earth. They have to eat, work as a part of a team, Subjects: Living in space. exercise, relax, maintain hygiene, and sleep. The only significant differences from living on Description: Earth are that they operate in the confined This program discusses the similarities and space of the orbiter cabin and differences between living on Earth and living that they, and all objects inside the cabin, in space. float. Actually, floating is not quite the correct word to use because in order to float, astro- Science Standards: nauts have to have something to float on. Physical Science The floating effect is called microgravity. - Position and motion of objects Microgravity refers to an environment Life Science in which the local effects of gravity have - Organisms and environments virtually been eliminated by free-fall. For example, imagine that you and a friend are Science Process Skills: riding in an elevator car when the elevator Observing cables break. As you plummet down the Making Models elevator shaft, you and your friend experience Investigating microgravity. In other words, you are falling together inside the car. This makes both of Mathematics Standards: you appear to float. Problem Solving Of course, gravity has not really gone Geometry away when you fall, but its effects inside the elevator car have. For example, what would the dial on a bathroom scale read if you could stand on it as you fall? Because of microgravity on the Space Shuttle, some jobs become a little more difficult, like handling tools and fluids. If you are not careful, things will float away. Eating is also more of a challenge and so is going to the lavatory. Other jobs, however, become easier. Moving about is very easy and so is reaching the top shelf. Moving massive objects is very easy because they feel like they do not have any weight. But, once you get a massive object moving, you have to be able to stop it too. Otherwise, it will collide with the inside walls of your spacecraft with the same force you used to get it moving.

Microgravity Through Falling Tight Working Spaces

Materials Materials Paper cup Four tables Thread Art supplies Colorful wooden bead (1-2 cm in diameter) Building blocks Several paper clips Action toys such as construction sets Cellophane tape Procedure Procedure Demonstrate the importance of teamwork and You can show how objects appear to float by cooperation by creating a small work space in tying a wooden bead to a paper cup with the classroom with four tables arranged in a thread and dropping them together. square so that there is a small working space Assemble the demonstration as shown in the in the middle about large enough to fit a small illustration below. Because of air friction, it couch. Place art supplies, building blocks, may be necessary to add a few paper clips to and other items around the tables. Make up the bottom of the cup to make it fall as fast as several jobs, such as drawing a picture of the the bead. Hold the cup high in the air by the Space Shuttle, folding a paper airplane, or bead and drop it to the floor. Observe the building a tower of blocks. The jobs should bead and cup as they fall. Try letting go of involve sharing tools and supplies. Select the bead again, but this time hold on to the seven children to work inside the space at a bottom of the cup. How does this time. Give them a time limit for completing all demonstration show that free-fall creates the jobs. Have other students observe the microgravity? activity and take notes of problems they see and more efficient ways of doing things. After other students have tried the tasks, hold a group discussion to talk about what was learned. How does this activity relate to working on the Space Shuttle?

Materials Materials Instant chocolate pudding (several packages) Various items such as balls, paper, coins, Plastic self-sealing bags (sandwich size) tape, pencils, etc. Water Spoons Procedure Ask your students to try to invent games and Procedure other forms of relaxation that could be used Show how space foods are prepared in on the Space Shuttle during periods of free space by making chocolate pudding. Add time. Point out to them that games requiring about one quarter of a box of instant pudding small pieces could be a problem if the pieces mix to a plastic bag. Add water to the bag drift away. Test the games to see how much according to directions. Seal the bag and fun they are and how well they would work in begin kneading it until it is ready to eat. This space. activity shows how astronauts prepare dry- mix, and freeze-dried foods in space. Preparing the food inside plastic bags prevents water from escaping inside the Space Shuttle cabin. Other kinds of food used in space include fresh fruits, dried fruits, nuts, and pre-cooked foods in foil/plastic pouches.
