Science

In Science our new topic is food and digestion. The other day we did an experiment trying to see if there is protein in curtain food.  We had eggs, milk, and butter.

Aim: TO test if a sample of food contains protein

Equipment: Test tube, Sodium Hydroxide (NaOH), Copper sulfate (CuSO), Food sample

Method: WHat we did is we got all of the equipment. Our food samples were Eggs, Milk, Butter. You put a little bit of the sample into the bottom of the test tube ( about 1-2cm in the bottom of it)  and then we put about 3-5 drops of each of the chemicals.  We then shook the test tube gently side to side to let it mix together. If it is positive with protein the liquid will go purple and it will remain blue if there is no protein present in the sample.

Resaults: 
                Milk                                                Egg's                                          Butter

NZ Government

L.O Understand how the New Zealand government is structured and how people can have a say.

In New Zealand there are different types of government. Legislative, Executive, Judaical. Legislative government - Parliament makes the laws.

Executive - Government: Cabinet - Develops and administers laws.

Has the power to make decisions

Judaical - Courts, judges - has the power to interpret laws (what they mean and how they work).

An Interesting fact:

• In 1893 women were granted the vote after a petition with 32,000 signatures was presented to parliament.

This term we have been learning about government. For this we got to choose a different type of government and I chose to do communism in north Korea. This is what I have done and some of the information I have found out. 
  

Eye Dissection

This week in science we have been learning about the different parts of the eye. For an experiment we got to dissect a cows eye.

Aim: TO find out all of the different parts of the eye.

Method: What we did is we got All of the equipment we needed and we had to start by cutting off all of the fat around the outside of the eye.  What we did after that is we cut a small hole in the cornea (small layer over the pupil to protect it) And squeezed out all of this clear liquid.  We found The Retina, and we detached the lens and had a look at that.

The lens focuses the light.
The pupil lets the light in
The iris limits the amount of light that gets let in.


I learnt that when you dissect a cows eye, it looks disgusting and i don't like it at all. but i also learnt different parts of the eye.

Have you don't this before?
