We will have a science test on our light unit the Tuesday after Thanksgiving. I will send home the study guide, which I also put below. I will also send home the articles and activities that we completed to help with studying.
If you have any questions, leave a comment below, email, or text!
Light Energy Study Guide
You will need to match the words with the definitions.
- Light- a form of energy that you can see

- Light can come from many sources.
- The moon is not a light source.
- If I shine my flashlight on a clear window, the light would pass through the window.
- An example of a translucent material is a piece of tissue paper.
- When light waves strike an opaque object, a shadow forms.
- When light strikes a bumpy surface, the light bounces off and scatters in all directions.
- When light strikes a smooth surface, they bounce off and are reflected.
- An object’s shadow is sharp and clear if the object is close to the wall.
- An object’s shadow is blurry if the object is far from the wall.
