3. What is unusual about the liner or “long johns” of an EMU?

They are filled with tubes of water to keep the astronaut cool.

4. How do astronauts make the EMU’s fit the different size bodies?

All pieces come in different sizes and can be attached to the suit.

5. What does the PLSS carry?

Enough oxygen for 7 hours of work outside the cabin.

Keeping Space Clean Answers

1. Why must trash be stored so carefully on the Space Shuttle?

It quickly breeds unhealthy germs that can rapidly spread in a closed area like the Space Shuttle.

2. What do astronauts do with left over food and empty containers?

They are put into bags and tightly sealed.

3. Where is garbage placed on the Space Shuttle?

In a special storage locker that is emptied upon their return to Earth.

4. Why do you think waste materials are brought back to Earth?

Come up with your own reasoning!

5. How could waste and laundry become a problem on the Space Station?

Come up with your own reasoning!

Grade 7: Some Chapter 3 Definitions for Review

Recovery: A return to a normal state of health

Replanting: To plant (something) again or in a new place

Financial Benefit: to receive a monetary (money) gain; e.g., receiving money from an activity

Social Benefit: an advantage to society; e.g., jobs become available after a new company moves to a town

Environmental cost: a negative effect on the environment due caused by human actions; e.g., animal habitats are lost when wetlands are developed.

B.

• A paragraph is written explaining the results of the comparison with another student’s game

C.

• Theoretical probabilities are accurately calculated
• All work is shown
• An explanation of the process is included

D.

• Student explained what changes were made to their design and why they made these changes

E. and F.

• Experimental probability for a minimum of 50 trials is included
• Results are organized clearly in a table or chart

G. and H.

• A paragraph is written explaining the results of the comparison between theoretical and experimental probability
• Paragraph should explain why the theoretical probability and experimental probability are close or why they are different

I. and J.

• Student creates a spinner that accurately reflects the theoretical probabilities or their game
• Experimental results are recorded for a minimum of 50 trials of the spinner
• A paragraph is written comparing the experimental results of the spinner and the game
• Students provides reasoning for their results
