Biuret Test

Aim: To test if a sample of food contains protein.

Method: 1. Place about 2 ML of the sample into a test tube and add 5 drops of sodium hydroxide. 2. Add 5 drops of copper sulfate. 3. Shake the test tube gently from side to side. 

Result: If the solution remains blue, then no protein is present. if the solution changes to a purple colour then protein is present. 

Conclusion: Since most of us didn't get it to work it just stayed blue. But if we were able to get it working it was meant to change colour to purple. 

Social Studies:

Social Studies: 

For social studies we recently did a test and I think I did well but there are some things I need to work on. Like for example I need to work on my mapping and labels/titles. I also need to re-read the questions again and understand what the question is asking. I also need to correct my wording so the reader can understand what exactly I'm saying.
