Objective
By the end of this lesson, you will be able to construct a mechanical model of the solar system and understand the relative positions and movements of the planets.
Materials and Prep
- Cardboard
- Colorful markers
- String
- A small light source (like a flashlight)
- Scissors
- Tape
- Ruler
- Glue
- Printed images of the planets
- Pencil
No prior knowledge is required for this lesson, just come with a curious mind!
Activities
-
Create a scale model of the solar system on cardboard. Use the images of the planets to draw and cut out their shapes.
-
Label each planet with its name and position from the sun. Use the ruler to measure the distances accurately.
-
Attach the planets to the string in the correct order, starting from the sun. Hang the string from a fixed point and observe the model from different angles.
-
Use the small light source to represent the sun and see how the shadows cast by the planets change as they orbit around it.
Talking Points
-
Our solar system consists of the sun and eight planets that orbit around it.
-
"The sun is like the star of our solar system, and the planets revolve around it in specific paths called orbits."
-
"Each planet has a unique size, composition, and position from the sun. This affects how they move in space."
-
"The distances between the planets are vast, and it takes a long time for them to complete one orbit around the sun."
