I. Purpose
The purpose of this lab was to find out information on different elements. I am specifically studying the mineral iron, and how much iron I’m getting daily.

II. Background
Iron is a mineral that is found in foods such as chicken, lean beef, and dark green vegetables. The recommended daily allowance for this mineral is anywhere between 10mg-18mg depending on how old and big you are. The benefits of iron are very good for the immune system and it can help stimulate your appetite. Iron also carries oxygen to all your body tissues. If you have a deficiency of iron it may cause tiredness and insomnia. Insomnia is a type of sleeping disorder. It may also cause pallor. If you have pallor it will cause pastiness and wanness. Now if you get to much iron it may lead to heart and liner problems. Iron is a very important mineral that keeps your body working properly.

III. Procedure
1. Mineral that interested me was found
2. Food and minerals are recorded in a data table
3. Food that I ate was recorded for 5 days

The table consisted of 3 columns. One was for the food, another for the portions and the last for how much of that mineral there is.


IV. Data
Foods Dates Servings Iron amount
3-Dec
Waffles 1 2mg
Goldfish 2 1.2mg
Ramen 1 .2mg
Bread 2 1.6mg
P.B 2 .8mg
Pepsi 1 0mg
Water 1 0mg
4-Dec
Waffles 2 4mg
Cookies 2 .8mg
Noodles 3 0mg
Crackers 2 .8mg
Bread 1 .8mg
P.B 1 .4mg
Pepsi 1 0mg
Water 1 0mg
5-Dec
Waffles 2 4mg
Cookies 2 .8mg
Ramen 1 .4mg
Burger 1 1mg
Pepsi 1 0mg
Water 1 0mg
6-Dec
Waffles 2 4mg
Subway 1 2mg
Cookies 2 .8mg
Crackers 4 1.6mg
Pepsi 1 0mg
water 1 0mg
7-Dec
Mcgridle 1 1mg
Pizza 4 4mg
Pepsi 1 0mg
Water 1 0mg

V. Calculations
a. My daily average intake was 6.32mg of iron. I got this by taking
my average intake and dividing it by how many days I experimented.

31.6(mean average intake)/5(days)= 6.32mg

b. Figuring out how to convert percent of a mineral off a food
label to mg or ug is not very hard. First you find the percent
of the mineral in your food. Second you find out the RDA of your
mineral. Now take the percent of the good and multiply it by
the RDA.

example- The RDA of iron is about 10mg. The food you just ate has
10% of iron. Now multiply 10mg by .10 and you get 1mg.
So there is 1mg of iron in that food.

c. I was deficient by 6.84mg of iron. I found the out by taking
the RDA and subtracting my daily intake then dividing by the RDA
again.

10(RDA)-31.6(Average intake)/10(RDA)= 6.84mg

VI. Conclusion
In conclusion the purpose of this lab was to find out infromation on different elements and studying a specific mineral to see if you are getting the right amount. My results showed my I was deficient. I was 6.84mg under what I needed daily. My percent error was 6.84mg deficient of the RDA. Some errors I made while doing this lab was not counting all of the lunches I ate, which was 3 out of the 5 days. This could have boosted my daily intake. I also eye balled some of the servings of foods I ate. I measured the food by servings on the back of the food label. To improve my results I would definitely not eye ball any of the foods I ate. I would also record all of the foods I ate and not leave some out, because I forgot. Iron is a very good mineral that your body needs. If you don't have enough iron you could be very tired or might have insomnia. If you get enough iron daily it can help boost your immune system. The RDA of iron is 10mg, and you can get iron from foods such as chicken, and lean beef.


Yeah I had to type is some where. So might as well post it too. Tell me what you think?

Edit- data table is screwed up.

Other than that, Its great! Good Job!

You have a Title, Purpose, Background, Procedure, Data Table, and a Good Conclusion.
