Aim: What nutrient foods are in different food...
Hypothesis:
What I think is in each food - (Bread, Milk, Apple, Potato, Egg, Glucose)
For the hypothesis, I would think that bread is a complex sugar, a Sugar/Lollies simple sugar, or an Egg would be protein, and Apple would be a complex sugar, etc...
Carbohydrate - Sugar - To make energy...
Protein - For growth - To repair muscles...
Lipids - Fat & Oils - Insulate/Protect organs, energy...
Equipment: Test tube - Iodine solution - Food sample...
Complex - Long slow energy...
Simple - Quick short energy...
Method: 1, 2, & 3...
1. Iodine, we used two drops of iodine on each food...
The foods, Apple - Banana - Potato...
If food turned black when fused with iodine, it means that they are complex sugar...
Results - They all seemed to turn black which means they are complex sugars...
2. We also put two drops of iodine in another bunch of food samples,
glucose - milk - egg...
Results - Our test 2 food samples turned a yellowish brownish color therefor there are no complex sugars inside of these foods...
Now we put 5 drops of benedict solution into all of the foods we have tested on - we also heated this benedict solution to see a different result, and we learned that some of the food samples can change color when heated, like orange-red - blue - purple...
Results - It turns out that all are simple except the potato, it was like a complex but not quite, and also the apple & glucose was a complex sugar...
3. Ok now with our third tests we got all the food samples and put 10 drops in each of the samples, five in each bottle with two different bottles of chemicals, Sodium Hydroxide-(NaOH) and also Copper(II) Sulfate (CuSO4)...
Results - Most of all the foods turned blue & purple, the apple - banana - egg - glucose/sugar - milk - potato...
Conclusion - My hypothesis was somewhat right and wrong for a few reasons, mostly because I knew that bread was actually was a complex sugar and that the sugar/glucose was a fast-flowing sugar which means it was a simple sugar which is kinda estimated because some people already know that sugar/lollies are simple sugars...
Discussion:
We found out that the bread isn't a fast-flowing sugar, it is a complex, mostly because it has starch inside of the bread...
We also found out stuff about if you put different types of chemicals inside of the food samples - they could change color and identify if the food sample is a Complex sugar, Simple sugar or a Protein...
Great first science Blog Niko! You did really well with explaining observations and things you learnt :)
