Senses We have 5 senses. Today, we are going to focus on sight.
Learning Objective • I can name the 5 senses. • I can name the parts of the eye. • I can discuss what we can do with the senses.
How many eyes do you have? What do you use your eyes for? Name something colourful that you look at. What colour are your eyes? What are the parts of your eye? What is found around your eye? What might some people use to help them to see? How do you look after yours eyes? Who helps to care for your eyes?

Are there any words that you don’t know? Eyelashes The eyelashes protect your eye from dust and other small objects falling in. Eyebrow The eyebrow stops sweat, water and other debris from falling into the eye socket. Iris This is the coloured part of the eyeball. Pupil The pupil is the black circle in the centre of the iris, which is really an opening on the iris, and it lets light enter the eye. Eyelid The eyelid protects the front part of the eye. The lid helps to keep the eye clean and moist by opening and shutting several times a minute (blinking). Sclera The white part of the eyeball is called the sclera (say: scl-air-uh). The sclera is made of a tough material and has the important job of covering most of the eyeball.
Sight Experiment What you need: • Five coins • A small paper cup • A table where you and a partner can sit What to do: • Put a cup in front of your partner. It should be about an arms length away from them. • Ask your partner to close one eye. • Hold one of the coins in the air an arm’s length above the table. Move it around slowly. • Tell your partner that you’ll drop the coin whenever they say, “Drop it!” The idea is for your partner – with one eye closed – to judge when the coin is over the cup so that the coins will drop into the cup. • Give your partner five tries with one eye closed, then five tries with both eyes open. Which way worked the best?
What has this experiment taught us: Two eyes help you to better judge where objects are.
Plenary Turn to your partner Tell them 3 facts that you know about eyes.
