Study Notes
Day 1: Importance of Science
- Science is important.
Waves and Their Applications
- Unit 1, Module L covers waves and their applications.
Standard MS-PS4-2
- Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
Day 2- Day to Day Application of Refraction and Lab
- Simulations on refraction
- Everyday applications of refraction
- Explanation of optical illusions
- Investigating refraction in different mediums
Vocabulary
- Optical illusion
Starter
- Illusion is a deceptive or pretended appearance or impression.
What is Optical Illusion?
- Refraction causes optical illusions.
- The perceived position of an underwater object is different from its actual position.
- Light doesn't travel in a straight line when passing through mediums with different densities.
- Our brains interpret light as traveling in a straight line.

Check Your Understanding
- Young birds learning to catch fish face challenges.
Which One is the Actual or Real Fish? Explain
- A diagram shows two fish, one appearing to be in a different position due to refraction.
Due to Refraction
- The apparent position of an object may differ from its actual position.
Day to day experience of refraction (optical illusion)
