10.05.10 When 4M became opticians!

This afternoon we were learning to be scientists. Miss Martindale posed us the question ‘Who has the best eyesight in 4M?’

We worked independently in groups of four to solve this problem by designing our own eye test.

We had to think carefully about how we would make it a fair test so that it gave reliable results!

I wonder if we will find that our tests are reliable (give the same results) when we compare as a class?
