The EYE

Tuesday, February 26, we talked about the eye and how it functions to allow us to see.

We turned on and off the lights to observe how our pupil changes size to allow more or less light in.

We also read different articles about parts of the eye and eye abnormalities and then shared what we learned with the class.

At the end of class, we found a video of a basketball player getting his eye knocked out of the socket. It was gross, yet cool, according to middle schoolers. Here's a link.

The COLORS of the Rainbow

On Monday, February 25, we talked about why we see different colors and light.

First we took a glass prism and a flash light and observed how white light is made up of all the colors on the spectrum. You can see the color spectrum when light refracts (or bends) through a glass prism.

In this picture you can see the color spectrum, somewhat. Pictures don't capture the colors very well.

The student is shining the flash light through the prism to see the color spectrum.

On the wall is a nice view of the color spectrum. 

Once the students figured out the best way to shine the light at the prism to see the color spectrum, they drew the colors they saw in their notebook. 

Reflection Challenge

On Friday, February 22, we had a reflection challenge. There were six stations at which we had to reflect a laser beam with mirrors to a target. At each station the target was in a different place and required the mirrors to do something different. We had to use at least 3 mirrors to reflect the light to the target. Groups got more points if they added more mirrors. The laser pointer couldn't be moved from its original position.

The target for this station is under the table. "Under the Table"

The target for this station is on the table. "Nose Dive"

"Zig Zag" 

"Circle"
