We have been doing eyes at school and we have discovered that every ones eyes are just about the same.  they have a pupil (which is actually a hole that opens wider when it is dark and shrinks when you go into bright light) an Iris (which is the coloured bit of your eye ) and a cornea (which is the gloppy clear stuff covering your eye). next we venture into the eye and what we see is a lens ( which is a hard thing that helps you to see things if your lens is too skinny or to fat you may have seeing proplems ) then we see the retina ( which is a clear liquid inside your eye which captures the images you see and processes them to the brain lickety split in less than a millisecond !)  at the back we have a little dent which is called the fovea ( which is where the images bounce off into the nerve which takes them to the brain.)

Part One:

step 1.    Come up with a hypothesis

( An hypothesis is a theory which is always a statement never a question it has to be able to be answered with either a yes or a no)

step 2. create a method.

( a method is something like a recipe it helps you to do the same thing every time.) you can write or draw the method

step 3. Create a list of what equipment

you need.

step 4. set up your site and always make sure

that you have a notepad and pencil to write down observations.

step 5. once you are finished your science investigation use your notes to observe

how well it worked ( observation is just saying how you saw it happen)

step 6. Findings ( findings is what you think and whether your hypothesis is true or not.)

Part two:

we need our science investigation to be fair for example: if you were doing a investigation on how long it takes a daffodil to change colour

and you put all food colouring in one jar and no water and another with 99 percent water and 1 percent food colouring it would not be fair would it? so we need to have the tests exactly the same every time.

Part three:

here are a few ideas for an science investigation…

1. fish can change colour depending on what food colouring you put in their water.

2. at toilet paper roll can last outside 30 days without biodegrading.

3. a cow can live on two litres of water a day.

4. tadpoles only take 40 days to grow into a frog.

5. A train can squash a coin flat.

Which science investigation do you think is most intresting??

Please leave a comment saying which one you like best
