The Magic School Bus Sees Stars

Field Trip Notes
When the kids see Horace Scope on the Star Shopping Network, they decide to buy Dorothy Ann a star for her birthday. Not wanting to buy something sight unseen, the kids blast off in The Magic School Bus to inspect the merchandise. They visit a young star, and then a middle-age star - but its the third, and last star they decide to buy. But when they give Horace their money, KABLOOM! the star explodes! Does this mean their star is gone forever?
Shine On

Going Hands-On

Time: 30 minutes
Group Size: 4

Dorothy Ann has a nifty new telescope, but she still enjoys looking at the stars with eye power alone. You kids report star counts and explore why we dont see stars during the day.

What You Need
For the Class
For Each Group
  • Pencil or pen
  • Bright flashlight

Ahead of time: Encourage students to do the Star Count activity with their families. Set a date for Star Count reports.

Talk About It

Let students report results of their Star Counts. Ask: Who saw the most stars? The least? Why did some see less stars the n others did? (Light from surroundings or a bright moon fades out some stars.)

What To Do
  1. Ask: Do stars shine during the day? (Yes, but atmospheric gases, dust, and water vapor scatter sunlight passing through. This veils stars until the sun sets.) Record students’ ideas.
  2. After kids punch out the Astro-Liz “constellation,” have them cut out the foldover. Fold the white flap over the dark Astro-Liz flap. Ask: What do the holes represent? (stars) The flashlight? (sun) The cover flap? (atmosphere)
  3. Tell kids to pretend it’s nighttime. Hold up Astro-Liz to a bright window, white flap facing them. Do they see “stars” through the “atmosphere” (cover flap)?
  4. Ask: When the sun comes up, do you see stars? Let kids shine the flashlight on the coverflap “atmosphere.”
  5. Ask: Why don’t we see stars during the day?
