Students will be able to:
use information from internet access and classroom discussions to
-determine how light and patterns create images that can be deceptive or misleading to our brains.
The do now on Wednesday was to review mini assessment two.
The do now on Thursday was to review mini assessment one in preparation for the interim assessment next week.
The do now on Friday was to make a KWL chart on optical illusions.
Those classes that needed to view the BrainPops on color, light, and refraction/diffraction did so.
Those classes that needed to demonstrate transverse waves with the mini slinkys did so.
Students took notes on light and how light can be changed by going to Dr. Gayden's Science Zone and clicking the 7th grade link for Wednesday, 3 November, 2010. Basically, the notes should include that:
Light:
-is a form of energy.
-is part of the electromagnetic spectrum that we can see.
-travels in a straight line or path called light rays.
-travels at a speed of 300,000 kilometers per second (186,000 miles per second).
Light can be controlled by:
-blocking it with something to create a shadow.
-reflecting it by changing its path with a mirror.
-bending it by changing its direction by making it pass into another transparent material of different density, like glass or water, called refraction.
Students read about optical illusions and created their own.
Since Science Fair projects are due on Friday, there was no nightly home learning assigned.
