Connection To Curriculum: Science, Mathematics and Technology

Teacher Prep Time: 3 hours

Lesson Time Needed: 3 hours

Complexity Moderate

Keywords: planet sizes, planet comparisons, Earth vs. Mars, models, science process, scale, orbits, solar system, sun, sizes

Materials:

Balloon (for the model sun)
Metric ruler
Miniature marshmallows
Poppy seeds
Mustard seeds
Circle-shaped cereal
Popcorn kernels
Dried peas
1-centimeter gum balls
Black pepper
Glue
Model Planet Cards

Description
This lesson allows students to visualize the comparative sizes and distances of solar system bodies by making solar system objects to scale using common objects, walking off the distances between planets and participating in a Web-based Sun/Earth scale model activity.

Objectives
Students will:
• Demonstrate the size of the sun and the bodies of the solar system on the ten-billionth scale.
• Construct and walk the distances between the bodies of the solar system on the ten-billionth scale.
• Compare the temperature, diameter and distance to the sun with familiar things on Earth.

Lesson Activities and Sequence

  1. Exploring Planet Sizes
    This activity looks at the sizes of the planets and takes place in the classroom. Students predict the size of Earth and Jupiter and find foods (like cereal, gum balls, etc.) that are about the size of each planet.
    Keywords: planet sizes, comparisons, Earth as a peppercorn, edible

  2. Walking Planet Distances
    This activity requires the class to go outside to walk the distances between the planets.
    Keywords: planets, scale models, distances, modeling, orbits, sizes

  3. Solar Pizza
    Students compare the temperature, diameter and distance to the sun with familiar things on Earth.
    Keywords: planets, sizes, planet temperatures, sun, comparing planets, distances in space
