Part 1 How Big Are Objects In Space?
What to Do: 1. Look at the Space object cards. 2. Thinking about what you and your partner know from experience, put the objects in order by actual size. 3. Put the objects in order from smallest to largest. 4. Write the names of the objects in the chart below. 5. Write the actual size in the chart as your teacher tells you. 6. Examine the sizes given and place the real size ranking in the chart. Observations:

What To Do:

How Far Away Are Objects in Space?

1. Again, look at the Space object cards. 2. Thinking about what you and your partner know from experience, put the objects in order by how far the object is from earth. 3. Put the objects in order from closest to farthest. 4. Write the names of the objects in the chart on the next page. 5. Write the actual distance in the chart as your teacher tells you. 6. Examine the distances given and place the real distance ranking in the chart. Observations:

Questions: 1. Why do you think it was difficult to determine size and distance?

2. What surprised you in the size rankings?

3. What surprised you in the distance rankings?

4. Many people think that the Hubble Space telescope is farther away than the moon. What did you and your partner think?

5. The picture of the Hubble Galaxies was taken by the Hubble Space telescope. Until that telescope was placed in orbit scientists thought that area of the sky was empty. What does this information make you think about?
