Nutrients - Testing

For the last three lessons, we were working on learning about what the body needs in terms of nutrients. We had to do three experiments to see if the foods we had were carbohydrates like simple sugar and complex sugars or if it were a protein. We split into groups and in my group, we had Lyan, Alliah, Milan, Lucy, and me. We started off by thinking about our hypothesis and then moved on to the real experiment. We used milk, egg, bread, sugar, apples, and potatoes.

Test 1 - Simple Sugars

Hypothesis -

My group and I think that the simple sugars were apples and sugar.

We put strips of food into test tubes adding benedict solution and putting it on the heat for 1 minute to see if it changed into an orange color. simple sugars.

We found that the only simple sugar in the groups of food was the apple.

Test 2 - Complex Sugars

Hypothesis -

My group and I think that the complex sugars were bread, milk, eggs, and potatoes.

We again put strips of food into the test tubes this time adding 5 drops of iodine. We could tell it was a complex sugar if it went for brown to black the moment it touched the food.

We found that bread and potatoes were the only complex sugars out of the group.

Text 3 - Proteins

Hypothesis -

My group and I thought that the milk and eggs were the proteins of the group.

We put the strips of food in adding 5 drops of NaOH as well as 5 drops of Cuso4. We could tell it was a protein when it went from blue to purple.

We found that the milk and eggs were the proteins.
