Where is Space?

Target:

I can explain where space is and how it’s defined.

Questions:

1. How would you define space?

2. Read the text book and/or look up how space is defined in several different sources. In the space below compare your original thought to the textbook versions.

3. Use the chart “How High is Space” to complete the following chart.

|Altitude |Object |

| |The Moon |

| |International Space Station |

| |Space starts here |

| |Oxygen only one percent of that at sea level |

| |Tallest building |

| |Surface of Earth – Sea Level |

The Solar System

Target:

I can describe the primary outputs from the Sun that dominate the space environment.

4. Read the section of the textbook pages 74 - 75, read the article “How the Sun works”, and view the video “Inside our Sun a deeper look“. Answer the following questions:

Article: “How the Sun works”

Video: “Inside our Sun a deeper look”

a. What fuels the sun?

b. List and describe the Sun’s two forms of energy output.

c. What are solar flares? How do they differ from the solar wind?

The Cosmos

Target:

I can provide some perspective on the size of space.

5. What units of measurement are used to discuss distances in space?

6. What is the closest star to Earth? The second-closest star?

The following are optional activities or sites to explore Space:

Astronomical Distances:

Section 3.2 The Space Environment and Spacecraft (pages 79-90)

Target:

I can list and describe major hazards of the space environment and their effect on spacecraft.

|I know, understand, and can discuss this key |I have heard of this key term but unsure of the|I have never heard of this term and have no |

|term. |complete meaning. |idea of its meaning. |

| | | |

6. Directions: This section review key terms are located on page 90 of your textbook. Look at the key terms and place them in the appropriate column in the following table that pertains to your background knowledge.

Your goal is to be able to put all of the vocabulary into the first column at the end of the section. As you progress through this section define those terms that you are unsure and don’t know.

Use the powerpoint for Chapter 3 along with your textbook to answer the following questions:

7. Watch the following video about testing a space suit. Write down 3 to 5 observations about a vacuum environment. (question 7 on NTG)
