 3. SOLIDS: The particles in a __**Solid**__ are closly bonded and dont not move around as much. they also dont have a lot of kinetic energy. for example a cement block is a solid therefor it can not change its shape and is not bendable. LIGUIDS: The particles in a **__Liguid__** are bonded together but the have seperated and are moving around in a pattern. they also have some kinetic energy. for example: water is a type of liguid. it moves around and can take the shape of the object it is in. GASES: The particles in a **__Gas__** move around freely and are not bonded at all. it also has lots of kinetic energy. for example: the gas in a pot is the hot air and when the pots lid jumps up and down means that the gas is trying to escape.

4. Do you think there is much of the iceberg under water or is it mostly above the water? no there is more ice under water then there is ubove How could you test your hypothesis?
 * Why do icebergs float in antarctic and arctic waters?** I think that the icebergs float because the iceburgs are lighter than the water so they float ubove the water

5. When you have a jar with a very tight lid, you can run it under hot water and it becomes easier to open. Why?

=Can you trust your senses?=

1. where does the most bending of the light ocur in the eye?

the most bending of light in the eye ocurs in the ritina. the back of the eye where the light hits. this is because the light goes through the pupil and travels towards the ritina.

2, describe how the lens work?

the lens work like a lens on a camera

=﻿ ﻿Student task 4 = = = ==

=﻿ ﻿Eagle senses = An eagles eyeball length is around 35mm. compared to a humans eyeball (24mm) thats much bigger then ours. an eagles visual acuity is 2.0 to 3.6 times better (depending on the type of eagle) than that of humans.
