Objective
By the end of this lesson, the student will be able to understand the basics of light, including its source, properties, and how it interacts with objects.
Materials and Prep
- A flashlight
- A mirror
- A transparent glass or plastic object
- A piece of colored paper
- A dark room or area
- No prior knowledge needed
Activities
-
Explore with a flashlight: In a dark room, give the student a flashlight and let them experiment with turning it on and off. Encourage them to observe how the light fills the room and how it can be controlled.
-
Reflection with a mirror: Show the student how light reflects off a mirror by holding the mirror in different positions and angles. Let them try it themselves and see how they can direct the light.
-
Transparency experiment: Give the student a transparent glass or plastic object and place it in front of the flashlight. Help them observe how the light passes through the object and how it may change in appearance.
-
Color exploration: Introduce a piece of colored paper to the student and ask them to shine the flashlight on it. Discuss how different colors absorb or reflect light, and let them observe the effects.
Talking Points
- Light comes from sources like the sun, light bulbs, and flashlights.
- Light can travel in straight lines and can be controlled by turning it on or off.
- When light hits a mirror, it bounces off and we can see our reflection.
- Transparent objects allow light to pass through them, while opaque objects block the light.
- Colors can absorb or reflect light. That's why things look different colors.
