This lab students learned bout optical properties of thin film. It worked well with Grade 6 since we studied light this year. I reviewed with Grade 7 and 8. We first did the simple lab of putting a pencil in a cup of water looking at the refraction of light.
We then watched:
This film did not have engaging speaking but had great diagrams, so I would use it but show the one below first, it made it easier for the 2nd to be understood.
We completed the lab and
and looked at the PowerPoint too. The students liked making a “rainbow”. We also discussed applications for cameras, eye glasses and other optical lens.
We saw:
I think the students were amazed how many thin films we use and they did not know what they were too. Although the lab was simple it was a great way to introduce this topic to the students and how nanotechnology works in this area.
