What science ideas did you learn?
This week we learned about eyes a little bit. We dissected cow eyes. We learned about different parts of the eye and what it was used for. I don't remember many of the parts, but there was a lens and a cornea. We also learned about movement. We learned that motion is relative. We learned that things appear to move when looking at them, but who is really moving. We also talked about from what perspective is and that might change what appears to be moving. Then we talked about how direction can change depending on your position. North, south, eats and, west don't move, but right and left do. If you and your friend stand across from each other and I tell you to point to the right you will point in opposite directions.
How did you learn these ideas?
We learned about the cow eyes because Mr. Finley ordered cow eyes and we dissected them. Step by step he showed us everything we cut and explained about it. We learned about motion because Mr. Segen held a ball in front of us and we had to look at it while he walked across the ball. Then he asked us who is moving us or the ball. We told him the ball is, but that's from our perspective. To him it looked like we were moving because he was walking a long side the ball.
Why is it important to know this idea?(What real world application is there)?
It is important to know about cow eyes because one day I could be a vet and be asked to look at a cow's eye. I would go to the farm and look at the cow's eye and think back to 8th grade and remember the cornea and what it is like and how it's supposed to look. Then I would look at the cow's eye and see its cornea was scratched and then I could help the cow.
