Simple Sugars

This week for Science, we have been working on food and digestion. Our first experiment was about how to figure out if something has simple sugar inside of it. The test is called Benedict's Test

Aim: To Test a sample of food to determine whether it contains simple sugars
Equipment: Bunsen Burner, Test tube tongs, Benedict's Solution, A sample of food.

Method:
1. Place about 2 mL of the sample into a test tube and then add 5 drops of benedict's Solution.

2. Heat with a bunsen burner until it changes colour, do not boil.

Conclusion: The colour of the liquid changed from blue to an orangy red hue. The sample we used was an apple.

Social Studies

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

In New Zealand there are three different types of governments, Legislative, Executive, Judicial. A legislative type of government is mainly a type of government that makes laws in our countries. Executives finalize the laws and make big decisions about our countries. A Judicial government also finalizes the laws, and figure out how they work and what the punishment could be.

This term for social studies we learned about the different types of government some of the different types of government are communism, dictatorship and democracy. We were then asked to learn about a certain country and the government style in that country. I chose communism in North Korea because it seemed interesting and I wanted to learn about it. Communism is a very weird type of government because everyone shares the same amount of money, everyone is employed, and everyone is educated.  We were then asked to create a presentation about what we learned about the system of government. This is my presentation about Communism in North Korea. 

Dissecting A Cow's Eye

Aim: To see the different parts of the eye and to understand what each part is.

Equipment: Cow Eye, Scalpel, Tweezers, Scissors, A Tray, Newspaper, Gloves

Method:

1. set up your newspaper and tray so then the surface you are working on is covered if anything spills. Make sure to wear gloves so then nothing goes on your hands

2. cut the fat and muscle off the eye until you can see the cornea, which is a huge black circle that is protruding from the eye.

3. carefully cut the cornea with the scalpel and face it away from you. black and clear liquid will ooze out so don't aim it at you.

4. after all the liquid is out cut the eye in half so there is a back and a front. 

5. from there you can see the different parts of the eye, you can pull out the lens, which is a clear hard part which focuses light into your eye. You can see the Retina which is a metallic blue coloured part of your eye. 

Results
The experiment was a little gross because it was very graphic but it was cool to see the different parts of the eye. I learnt that the eye is a pretty complicated part of your body.

Would you every do this?
