Biology

1: Place around 2 ml of the sample into the a test tube and add 5 drops of sodium hydroxide.

2:Add 5 drops of copper sulphate.

3:Shake the test tube and shake it gently.

Milk:Positive Potato:negative Egg:Positive Bread:negative

Glucose: negative.

Conclusion:Not all if the tests turned out to be positive and I'm surprised that bread had no protein, my hypothesis was right that not all of them were wrong and .

Testing for simple sugars….

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 hotplate until it changes colour.

I think that it will change colour and do something weird.

Conclusions:They turned out all positive(Bread,Apple and Potato), but milk turned blue because it has protein in it.

Egg had protein just like milk, but sugar had no protein as well. 

If it is a simple sugar it will turn blue then red/orange but
if nothing happens that means it's positive.

Aim: to see if different foods have simple sugars, complex sugars or protein in it.

Hypothesis:

It’s a complex sugar

I think they will have multiple things inside it when we test the foods.

Apple might act weird or something cool.

Bread will probably be the hardest to test.

Potato might have complex sugars.

Egg might be easier and most probaly have protein.

Milk will probably will have lots of protein and other good things for your body.

Glucose-Lollies

Apple- Complex sugar

Bread-Complex sugar

Potato- Complex sugar

Egg- Complex

Milk- 

Sugar-Not complex
