A blog where you can find out what we are doing in class, what homework is due, and odds and ends that might be interesting.
Students worked on a review sheet that covers all of the material from this unit (electromagnetic waves to mixing light and colors). Test will be on Friday, we will be discussing the review sheet in class tomorrow. Assignment: complete entire review sheet for the start of class tomorrow.
Today we discussed how the human eye perceives color and also talked about how color blindness can affect people. We also discussed how we see colors of light and pigment. Tomorrow we will be starting the chapter review, test will be Friday. No homework today.
Yesterday's convex lens lab was collected for grading. As a group, the results of the lab were discussed. Students took notes on drawing ray diagrams for convex lenses. We will continue looking at more lens diagram examples tomorrow. No homework due for tomorrow.
Students completed a convex light lab today. The data from this lab will be used to complete the post lab analysis. Assignment: Post lab is due at the start of class tomorrow.
Students watched an episode of Myth Busters pertaining to the idea that Archimedes was able to use mirrors to create a solar powered weapon capable of burning Roman ships. The design of this ancient weapon is thought to have focused light into a centralized point capable of producing temperatures high enough to ignite wood. The effect of numerous flat mirrors mounted at angles that reflect light rays into one centralized point mimics the way light rays interact with concave mirrors. Homework for tomorrow is to bring back signed grade sheets.
Students learned how to draw various ray diagrams for mirrors. These ray diagrams are used to predict the path that light will travel after it hits a mirror surface. Types of images formed by these reflecting rays were also explained.
Assignment: Unit 16B – Light, WS 2 Mirror diagrams
Students discussed their answers to yesterday's lab in small groups. Once they established what they believed to be the correct answers, each group put the answers on a white board. Groups then presented their findings in front of class. Tomorrow we will be further exploring the ideas learn from this lab.
