1. The difference between the particles is because in a solid the particles are held together by a strong and rigid bond. In a liquid the particles are weak. In gases the particles have no bonds what so ever, so thats why it is not together like a solid or a liquid. The solid and liquids can be touched because of the bonds in the particles putting them together and allowing us the touch them. But in a gas, there are no bonds, which makes it that there is no structure made and it causes it to be untouch-able and just floats in the air.

=CAN YOU TRUST YOUR SENSES? = 1. Where does the most bending of the light occur in the eye?

A: The lens.

2. Describe how the lens work.

A: It works by when the lens re-directs the light into the retina, which comes in upside down, but the optic nerve flips it around, giving you normal vision.

3. Why do we squint when exposed to bright light?

﻿﻿A: It happens because when our iris gets so small, that it is as small as it can get and the light is still bright, we will squint to minimise light intake.

4. Which parts of the eye are involved in focusing?

A: The lens and the retina. The rods and cones are also used identify light, and colours to let us show what the object looks like.

5. Discuss the implications of losing one eye.

If you lose your left eye for example, you will find it harder to see on the left because the vision from the two eyes come together, giving you a full view.
