Lesson 19A: Formation of the Solar System

 

Estimated Time: Two forty five minute class periods

Indicators(s): Core Learning Goal 1

1.4.9 The student will use analyzed data to confirm, modify, or reject an hypothesis.

1.5.4 The student will create and/or interpret graphics (scale drawings, photographs, digital images, etc.).

1.5.9 The student will communicate conclusions derived through a synthesis of ideas.

1.7.2 The student will identify and evaluate the impact of scientific ideas and/or advancements in technology on society.

Indicators(s): Core Learning Goal 2

2.2.1. The student will explain the role of natural forces in the universe.

At least-- formation of planets, orbital mechanics, stellar evolution.

Student Outcome(s):

  1. The student will be able to explain current thinking about the formation of the solar system by reading technical documents and viewing animation and Hubble Telescope Images of the solar system.
  2. The student will be able to explain how evidence from satellite data supports or refutes current thinking on the formation of the solar system

Brief Description:

In this lesson students retrieve what they already have learned about the solar system and then read a variety of technical documents and graphics to add to their knowledge base. There is also a connection made to contributions of a variety of cultures to our knowledge base. Finally, students are asked to refer back to their journal writings from the comparative geology of the solar system to support or refute current thinking about the formation of the solar system.

Background knowledge / teacher notes:

Each of the short video clips in this lesson may be downloaded and saved to the server for student viewing and reviewing.

Lesson Description:

ENGAGE

Vocabulary: nebula, planetsimals.

Engage students by having them retrieve what they know about our solar system. Ask students to include prior knowledge as well as knowledge from current learning activities. Ask students to organize the knowledge or create a concept map about the formation of the solar system.

Accommodation: The class could construct this concept map as a group if teacher guidance is needed.

Education Elements:

IMAGERY

This site contains a JPEG image of the planets in the solar system.

EXPLORE

Have students go to the University of Texas McDonald Observatory website, StarDate Online. Solar System Guide: Planet Formation. Available:

http://stardate.org/resources/ssguide/planet_form.html

Ask student to compare the information in the article to what they have in their concept map. Students should add information they do not have and delete any misinformation. Students may then click on the hot links to the right to continue to put together key ideas on solar system formation.

Ask students to click on the enlarged image of the Orion nebula to view an actual nebula. Students may use this photograph from the Hubble Telescope to add details to the concept map.

View Cloud collapse: face-on, and edge-on (1.7 Mbyte mpegs). both are quite short (seconds) but may be reviewed several times.

Formation of the Solar System. Scroll down to Web Resources:

and click on Cloud collapse.

Available:

http://www.ifa.hawaii.edu/faculty/barnes/ast110/fotss.html

Computer simulations of a cloud of gas collapsing to a thin rotating disk. Separate views face-on and edge-on to the disk are shown. Color indicates gas density, with blue for the lowest densities and red for the highest densities. Note: these may be downloaded in advance and saved on the server for student viewing.

After viewing these video clips students should add details to their concept maps.

View Planetary Motion- Inner planets, 231K, Inner planets 30 degrees tilt, 182K, All planets, 2 Earth revolutions, 297K, All planets, 4 Earth revolutions, 528K.

Our Solar System: The Planets and Their Motion. Scroll down to Planetary Motion. Available:

Each of these is a short video clip and may be downloaded to the server in advance.

After viewing these video clips students should add details to their concept maps.

Accommodation: Remind students to preview reading before reading as they click on the links

The teacher may want to begin to model this activity by demonstrating how the explanation can be written using the systems diagram as the graphic organizer and following the sequence of the diagram.

EXPLAIN

Journal Write:

Students should work in their groups to construct a systems diagram that illustrates the formation of the solar system.

Write an explanation of the formation of the solar system using the concepts learned in the exploration and organized in the systems diagram.

EVALUATE

Journal Write:

Think about and review the evidence gathered about the solar system in your Earth/Space Journal from satellites in the following activities: Comparative Geology of the Solar System: Atmospheres, Comparative Geology of the Solar System: Landform Mapping of the Terrestrial Planets, and Geologic Features of Outer Planet Satellites. Explain how the evidence from satellites gathered in these previous activities supports or refutes current thinking about the formation of the solar system.

Modification: Complete a graphic organizer with the class before writing.
