LESSON PLAN

SEVEN-STEP

**Agenda:** Astronomy (Stars & Light)** To Do List **Time (min)

**Anticipatory Set:** Vocabulary list, and researching the classes of stars.

Objectives: 1) CONTENT STANDARD 18: Students understand that the universe and planetary systems have evolved for billions of years and will continue to evolve.

a) **18.1** Constructing a model that describes the development of a star (birth, change, development and death).

b) **18.2** Using Newton's laws of motion and the concept of red shift to describe and predict a variety of universal phenomena (e.g., planetary orbits, galactic rotation, universe expansion, etc.).

c) **18.3** Inferring size, age, composition, mass, and temperature of stars and other celestial objects from information about light (and other electromagnetic radiation) received from nearby stars or H/R diagrams and spectrographs.

d) **18.5** Given various "nearby" stars, calculating the age a student would be if a radio message they sent today traveled to the star and back.

**Instruction: **Day 1:

- Students will copy standards 18.1 - 18.3, and 18.5 in their notebooks.
- In Cooperative Groups, students will develop a proposal that will satisfy 18.1
- Students may create a 2-D model from the following choices:
- A poster.
- Painting.
- Students may create a Multimedia model from the following choices:
- PowerPoint. Note: Large PowerPoints files tend to get corrupted easily, so using PowerPoint requires students to create 6-7 separate files to show their model.
- HyperStudio or Director. Note: HyperStudio is fairly easy to learn and run. Director provides more control, but it requires that students have had experience with the program before doing this project.
- WEB page or JAVA script. Note: This requires at least one student who is fairly proficient at WEB design.
- Students may create a 3-D model from the following choices:
- Clay
- Styrofoam
- Food. Note: Food must be coated in lacquer to prevent spoilage and/or pest control.
- In Cooperative Groups, students will rewrite 18.3 so that a 5
^{th}grader can understand the standard.

**Self-Check: Homework **(Research)

**Vocabulary: **Students will research the following words, and will attempt to write the definitions in their own words:

Star Classifications

Binary Stars

Luminosity

Mass-Luminosity Relation

Reflection

Refraction

Index of refraction

Hertzsprung-Russell Diagram

Determining a star's distance

Determining a star's radii

Determining a star's mass

Day 2: **Check for Understanding**

- In Cooperative Groups, students will share definitions. Students will work towards understanding the terms, rather than copying each other's definitions. The teacher will check each group's definitions.
- Review of the terms, and focus on reflection and refraction for the following lab.

**Self-Check: Homework **(Math & Graphing )

- Scientific Notation Problems
- Students will create the following three graphs based upon their solar system projects for all planets.
- Escape Velocity VS mass,
- Escape Velocity VS gravity, and
- Escape Velocity VS distance from the Sun.
- Students will write a paragraph that describes the above graphs, then indicate which graph best describes a planet's escape velocity.

Day 3: **Check for Understanding**

- In Cooperative Groups, students will correct their Scientific Notation and Graphs.

Instruction

- Introduce the Reflection/Refraction Lab.
- Students will write their introduction and methods for the above lab. (see the syllabus for details of the lab report format).

Day 4: **Instruction**

- Students will work in pairs on the Reflection/Refraction Lab.
- Students will prepare figures for the results section of their lab reports.
- Students will write their lab reports. Due the following Monday.

Day 5: **Instruction**

- Introduce proofreading.
- In Cooperative Groups, students will proofread their lab reports.
- Students will rewrite their lab reports based upon comments from their groups.

Day 6: **Check for Understanding**

- In Cooperative Groups, students will check their rewrites, turning in approved lab reports.

Instruction

- Introduce the Light Spectrum Lab.
- Students will research the above lab through handouts, and the Segway WEB site .
- Students will write their introduction and methods for the above lab.

Day 7: **Instruction**

- Students will work in pairs on the Light Spectrum Lab.
- Students will prepare figures for the results section of their lab reports.
- Students will write their lab reports. Due the following Monday.
