Science 3rd grade | UNIT 4: Our five senses 4.3 Sight
What colour eyes do you and your friends have?
Your eyes are fantastic.
They can see things close to you and much further away.
Some animals have very good eyesight and some animals do not.
Instead, the mole uses his nose to find his way around |

With our eyes we can see what is happening in the world. You can test your eyes.
Activity 4.3 (Make and use an eye test)
You will need: a large piece of paper - a metre ruler something to cover one eye
Choose a set of letters or numbers.
Print these in different sizes on your piece of paper.
Fix the paper 2 or 3 metres away.
Cover one eye while you read the letters or numbers out to check that you can see them clearly.
Now check your other eye.
Try your test with other people.
How far down the chart could you read the letters?
Was the result the same for both eyes?
Did other people have the same result?
