The chart below was projected on the whiteboard for the class to conduct this visual experiment: Follow the instructions for the activity or get a handout that outlines the activity in class.
Do Now: (this chart is displayed on the board but you could use almost anything-even a poster across a room).
1) Take off your glasses, look at the eye chart and answer, Which line on the chart can't you read? Write that down____
Now cover one eye and then the other while looking at the chart and determine
2) Which eye is your weaker eye? ________ (left or right)
Use that eye for the experiment
use one of the eye charts in the room:
Using one eye, your eye with the poorest vision, cover your good eye and determine; determine the line you cannot read , use that line for the activity
Classroom Activity:
1) make a small pin-hole in the cardboard provided,
Then Using the weaker eye, look through the small pin-hole and look at the line you could not read
2) What happened: _________________________
(How has your vision changed looking through the small pin-hole?)
3) Why do you think your vision has changed?

We will discuss our theories in class!
