Today in Science – Optics

Today we introduced optics and did two experiments.  For the first we created a lab format complete with title, problem, materials, procedure, and hypothesis taking educated guesses about what would happen when we looked at the arrow through a glass of water.  See the video from class below and the similar one found online.

For the second experiment we used ray boxes to create shadow with umbra and penumbra.  We drew and labelled these.

Here is a copy of the work sheet for this from class.
