The unit leads students through a series of carefully sequenced activities that introduces them to the behavior of light, its properties, and its many uses. Lessons are divided into 3 sections: Nature of Light, Reflection and Refraction, and Using Light.
The unit leads students through a series of carefully sequenced activities that introduces them to the behavior of light, its properties, and its many uses. Lessons are divided into 3 sections:
- Nature of Light-Students examine the sources of light, its travel in straight lines, shadows, and the application of the principles of its travel in a pinhole camera.
- Reflection and Refraction-Students investigate the reflection of light from plane and curved mirrors and the refraction through various media. They use their experimental data to develop an understanding of angles of reflection and refraction.
- Using Light-Students use combinations of lenses to construct simple optical devices, such as a telescope and periscope. Then they deconstruct a camera to examine its components and their function.
