1. Topic-
Relative Size
2. Content-
Relative characteristics including size of the Sun and Earth and the distance between them (using scale models).
3. Goals: Aims/Outcomes-
1.Correctly measure distance
2.Compare and contrast the differences between the Sun and the Earth
3.Learn how to use/make scale models.
4. Objectives-
1.Identify planets in our solar system and their basic characteristics.
2.Describe the earth's place in the solar system that includes the sun (a star), planets, and many moons.
3.Compare and contrast the size, composition, and surface
features of the planets that comprise the solar system as well as the objects orbiting them.
4.Relate planetary size and distance in our solar system using an appropriate scale model.
5. Materials and Aids-
Measuring Tape/Yard Stick, Chalk or Duct Tape (for marking distances), Supplemental Worksheets, String (optional)
6. Procedures/Methods-

A. Introduction-

1.Students will: Complete 2 KWL charts- write 3 things they know (or think they know) about the the Sun and 3 things about the Earth and what they want to know.
2.Students will also draw pictures of the Sun and the Earth based on what they already know (prior knowledge).

B. Development-

1. As a class we will go over concepts of measurement (including diameter).
2. We will complete sample activities similar to the one they will do on their own so they understand concepts of relative size and distance.

C. Practice-

1.Students will go to the library and research books about the sun and the earth and complete several comprehension worksheets to further their understanding of concepts.
2.Students will complete the actual activity using the scaled pictures and measurements in either the parking lot or hallway.

D. Independent Practice-

1.Students will complete a Venn Diagram to compare and contrast characteristics of the sun.
2.Students create posters and will also attach copies of the scaled Sun and Earth and write down facts that they have learned throughout the research.

E. Accommodations (Differentiated Instruction)-

1.ESL students or students with disabilities may work with a partner in the library to gather information. They may also choose a book at their appropriate level provided it covers the same material. They may write 1-2 things for each column of the KWL chart OR draw pictures to represent prior knowledge

F. Checking for understanding-

1.Formal-Students will be assessed on the completion of their KWL chart, comprehension worksheets,Venn diagrams, and posters.
2.Informal- Students will be assessed on how they work in their groups and their ability to follow directions and formulate questions for their KWL charts.

G. Closure-

1.We will wrap up with a discussion about anything new that they learned, what they liked or didn't like about the activity and how we could use what we learned about relative size and distance and apply it to other aspects/areas of learning.
7. Evaluation-
1.KWL charts will be evaluated to check for understanding from beginning to end.
