30 November Science 8 Planning the Solar System Model

Mindful moment.

Review previous DSN entry and Blogpost. (Make sure details of Solar System scale model project are clear).

Read today’s blog.

Prepare for record-keeping DSN entry in Astronomy folder.

Develop Chart with scale distances and sizes.

Like this one:

Solar System Chart

Actual Size
Scale Size
Actual distance from Sun
Scale distance from Sun
Direction of orbit (indicate frame of reference)
Time of orbit
Inclination of orbit to earth’s orbit
Interesting facts—atmosphere, composition, spin-rotation (direction, orientation, time, etc.), space craft visits, landings, etc.
Earth’s moon
*Alpha Centauri
  • Double-check calculations. What is the scale factor you are using? How many times are you shrinking the solar system to reach your scale?
  • Locate objects on map.
  • Build or select scaled objects to represent actual objects.
  • Plan still and video shots.
  • Plan commentary.
  • Practice inside with trundle wheel, objects, camera(s), commentary, etc.
  • Plan individual product.
  • Find out about Kepler’s discoveries–he only had an early telescope, no calculators or computers, how did he do it? http://www.historyoftelescope.com/telescope-invention/the-keplerian-telescope/

Next class we will depart immediately after the mindful moment. Bring all you need to class. If you wear a mask outside, bring that. If it is cold, bring a jacket or sweater.

See the description of the Summative Assessment Project below. You will build the model in groups, but the assessment project will be completed as individuals. We will use the sidewalk along the street along the west side of the school. We will begin in the next class. Be prepared.


Each class will use San Martin Marg for the site of their models. San Martin Marg runs along the west side of the school. In the picture above, note the scale at the bottom right of the image. You can print this image to help you construct your model.


“The exhibition begins with the sun, located at 13th and Baltimore, with the display running south along Baltimore through the Crossroads District, then ending in front of Union Station. The Voyage experience takes approximately thirty minutes to complete, walking at a leisurely pace from the sun to Pluto.”


***Summative Astronomy Sci 8 18-19 Making a model of our solar system to scale by size and distance***

***Groups prepare and construct the model.

Include the sun and all planets. Include Pluto. Include Ganymede (moon of Jupiter). Include Earth’s moon. Mark on a paper map the “location” distance to the closest star (other than the sun); It is a binary pair–Alpha Centauri <https://www.space.com/18090-alpha-centauri-nearest-star-system.html>. Is your map “big” enough?


  1. Make a video (5 minute limit) (with commentary) OR ebook showing a scale model of solar system with both size and distance illustrated to the same scale.

  2. Produce in hard copy and digital (in students’ DSNs) a written / sketched storyboard.

  3. Present in hard copy and digital (in students’ DSNs) equivalence chart / calculations to objects and orbits in the model.

  4. Provide information about sizes, distances and scale.

  5. Present in hard copy and digital (in students’ DSNs) the directions and inclinations of orbits. (Include interesting facts about the orbits and planets in the commentary.)

8.SC.BTH.A.2 – 2. Developing and using models

8.SC.BTH.A.5 – 5. Using mathematics and computational thinking

8.SC.BTH.B.3 – 3. Scale, Proportion, and Quantity

8.SC.BTH.E.2 – ESS1.B: Earth and the Solar System

Some student videos (these were group projects and were longer than the current limit of 5 minutes)
