4 GROUP D Space Food What nutrition requirements do astronauts have? Nutritious Meals What types of meals do astronauts take into space? How does food and water react in microgravity? How to Eat How do astronauts eat? What happens to the sense of taste in space? Making Food Taste Good How are meals prepared to fix this problem? 4

5 GROUP E Waste Management What problems can there be with using the restroom in space? Toilets How are toilets made to fix these problems? How would a normal shower react in space? Showers How do astronauts clean themselves? What would the effects of garbage be in space? Garbage What is done with the garbage created in space? 5

6 GROUP F Living and Working in Space Mrs. Keadle JH Science What problems could astronauts face trying to sleep? Sleeping How are those problems solved? What health issues can astronauts have in space? Personal Care How are astronaut s medical needs taken care of? Can astronaut s exercise in space? Health and Exercise How can they exercise and stay in shape in space? 6

7 GROUP G Spacecraft What stresses does a shuttle go through during lift-off? Living and Work Areas How is the shuttle constructed to make it through lift-off What is orbiting? Sleeping Areas How does the shuttle or space station stay in orbit? What stresses does a spacecraft experience when re-entering Earth s atmosphere? Hygiene and Personal Care How does the shuttle survive re-entry? 7

8 1 What work of Sir Isaac Newton helped others to understand and overcome the obstacles of modern space travel. A B C The laws of Planetary motion. The discovery of gravity. The invention of electromagnetism. 2 The floating sensation astronauts experience while in a space environment is due to - F zero gravity. G microgravity. H gravity. J loss of gravity. D The construction of simple rockets. 3 Which statement best describes the effect of microgravity on an astronaut s bone health? A B The amount of physical stress on bones increases, resulting in bone deterioration. The amount of physical stress on bones decreases, resulting in an increase in bone density. C The amount of physical stress on bones increases, resulting in an increase in bone density. D The amount of physical stress on bones decreases, resulting in bone deterioration. 8

9 4 Which of the following is NOT a limitation of the model? F size of the Sun 5 How can a model of the solar system be used in planning a trip from Earth to another planet? G H J size of the planets distances between planets number of planets A To estimate distance, travel time and fuel cost. B To anticipate the frequency and occurrence of meteorites and other objects in space. C To map flight plans that avoid solar flare-ups and solar winds. D To predict possible emergencies astronauts may encounter during space travels. 9

10 6 How does the space suit backpack help astronauts breathe in a space environment? F It maintains air pressure to keep bodily fluids from boiling. G It provides pure O 2 for inhaling and canisters to collect CO 2. H It stabilizes and internal temperature of 22 C (72 F). J It collects urine and solid wastes. 8 Why do astronauts wear space suits in swimming pools before participating in manned space explorations? F It allows them to work in a frictionless environment. G Gravity of water is similar to microgravity of space. H The load of the backpack is lightened by water, allowing astronauts to more easily practice space tasks. J Wearing a spacesuit in water simulates the weightlessness of space. 7 The insulated feature of space suit layers are designed to - A protect from radiation. B trap excessive CO 2. C regulate temperature. D provide pure O 2. 9 How does pressure in the astronaut s space suit help the body work? A The suit forces blood to certain parts of the body to counteract the absence of gravity. B The suit acts as an external pacemaker to regulate the heartbeat. C The suit regulates gas exchange between the oxygen pack and the astronaut. D The suit monitors the amount of O 2 to CO 2 in the blood. 10

11 10 All of the following are ways that atmosphere makes the existence of life on Earth possible EXCEPT - F G H J It shields the Earth from collisions. It offers protection from radiation. It maintains a constant temperature. It allows for gas exchange between plants and animals. 11 When NASA sends probes to distant planets they will normally go to another planet first, even though the probe will not collect any data from the first planet. Why do they do this? A B C To take pictures of both planets To make the trip longer To shorten the trip using the first planet s gravity to slingshot the satellite. D NASA does not do this. 11
