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
