STEP 1 - LIVING THINGS - 3rd and 4th class Investigations

How to discover the blind spot in our eyes.

We got our equipment and made a prediction as to how far away from our faces the sheet with the spot would have to be before it went into our blind spot. The children had to close their right eyes and to hold the sheet with the cross at arms length. The children had to bring the sheet as close to their face as possible until the blind spot disappeared. In pairs, they measured the distance from the sheet to their face to discover at what distance it was, that the blind spot disappeared. We then wrote up our results and conclusion. We discovered that at a certain point, the spot disappears because the light from it is falling on the blind spot of your left eye.


How to find your dominant eye
Firstly, we identified what we would focus on and we decided the side of the door was the best object that was in everyone's line of vision. The children wrote up their prediction as to which eye would be their dominant eye. The children used a pencil to line it up vertically with the edge of the door. They then closed each eye in turn. They discovered that with one of their eyes closed the pencil still lined up with the edge of the door. The opened eye that lined up perfectly with the door frame while the other eye was closed was their dominant eye.

The children had a fantastic time using their science and mathematical skills completing the Science experiments and we look forward to the next Science challenge.
