HOW DOES LIGHT TRAVEL?
This is an image that I have made to model scientific drawing, you can download this from the web page.
This lesson is a demonstration of how light travels. In the first lesson I have asked the students to write their understandings of light, this activity will allow the students to test their hypothesis about how light travels.
I will explain to the students that the purpose of these experiments is to test their original hypothesis regarding how light travels. This will also be an opportunity to demonstrate the importance of diagrams in scientific explanations and work through from the hypothesis to the testing to conclusion.
Questions for this investigation:
· Does Light travel in a straight line?
· Why do you think that?
· Can light curve? Why?
· Can light change direction on its own? Why?
I will display the sheet how light travels investigation and explain that these are the instructions for the investigation.
Read with the sheet with students and discuss the investigation, and explain that the investigation involves two steps by referring to ‘Procedure 1’ and ‘Procedure 2’.
