 Are all parts of the eye seen here involved in the function of sight?
 Are there any parts that could potentially sustain damage without making the eye as a whole lose its function?

 Turn to page 277 in your lab books and do activities
A and B (Acuity and
Astigmatism).

We aren’t using wall charts so 1 partner will hold the lab book chart and stand 1 foot
(1 tile square) away

Teacher gives worksheet of questions or problems.
Partner “A” will be responsible for the left-hand side. Partner “B” will be responsible for the right-hand side.
Partner “A” has the one pencil and the one paper. Partner “A” reads the question aloud and works through the problem aloud.
Partner “B” coaches and praises.
Partner “A” gives Partner “B” the pencil and paper.
Then Partner “B” takes the paper to the teacher for it to be approved.
Partner “B” reads the question aloud and works through the problem aloud.
Partner “A” coaches and praises.
Keep taking turns until teacher calls time.
Be prepared to share partner’s responses.
If you are caught breaking these rules, you have to do the entire worksheet by yourself.
