Equipment: Test tube, Sodium hydroxide, Copper solfate, food sample.

Method: 

Place 2 ml of sample into a test tube and add 5 drops of Sodium hydroxide.

Add 5 drops of  Copper solfate.

Shake the test tube gently from side to side. 

Results: If solution remains blue then no protein is present.  If solution changes to a purple colour then protein is present.

Testing For Simple Sugars  - Benedict's test

Aim: To test a sample of food to determine weather it contains simple sugars.

Method:
Place about 2 ml of the sample into a test tube and then add 5 drops of Benedict's solution.
Heat with a Bunsen burner until it changes colour. Do not boil.

Results:
A positive test for a simple sugar results in the Benedict's solution changing from a blue colour to a orange colour.
No colour change is a negative result.

Discussion: The apple changed colour so it's a orange colour.

Conclusion:  We tested the sample of food to see if it would change colour and it did.

Testing For Complex Sugars - Iodine Test

Aim: To test if a sample of food contains complex sugars.

Method:
1. Place about 2 ml of the sample in a test tube.
2. Add 3 to 5 drops of iodine and mix.

Results:
If complex sugars are present the iodine solution will change from a brown colour to a blue/black colour. If iodine solution does not change colour then no complex sugars are present.

Discussion:  The bread didn't change colour it was just black.

Conclusion: The bread was brown at the start and didn't change colour.

Drama - Cat costume

In drama we first planned out what we were going to for our costume. We had to make three posters altogether but at the time we just needed to do two.  After your finished we get all the stuff we needed to make cats. We could use the sewing machine and use makeup as well. Once we finished doing our costumes we took a picture and made our final poster.
