Fruity Goodness

An investigation of fruit's nutrition and their density.

Purpose

The purpose of this project can help benefit the society by allowing the public to know which fruit they should eat more of rather then eating other fruits that may not give them the nutrients they want/need. It can also show how a certain fruit could be just as sweet as some type of candy but be healthier for the person eating it.

Problem

Does a fruit's density have anything to do with it's amount of sugar, calcium, iron, and magnesium?

Hypothosis

If the fruit is denser, than the fruit will be healthier because the definition of denser is closely compacted in substance and if it is more compacted than the amount of nutrients it can hold is more than a less dense fruit.

Materials For The Experiment

-Oranges (10)

-Grapes (10)

-Pears (10)

-Apple (10)

-Banana (10)

-Triple Beam Balance

-Graduated Cylinder

-Water

-Calculator

Procedures For The Experiment


1.Create a table for the average nutrients including sugar, calcium, iron, and magnesium


2.Create another table containing the fruit name, volume, and density.


3.Find the mass/volume/mass/density for each fruit and put them in the previous table.


4.Repeat steps 2 & 3 until you have 10 total tables then create one more table for the


5.average volume/mass/density in each fruit.


6.Create a LINE graph, label the x-axis “type of nutrients, and label the y-axis “amount of fruit containing in grams.

Parts Of Experiment

1.Dependent Variable: Weight/Volume/Density of fruit

2.Independent Variable: Type of fruit

3.Control Group: N/A

4.Experimental Group-Organisms: N/A

5.Constant:

-Same Graduated Cylinder used throughout project.

-All Fruits bought at same grocery store.

Observation

The Grapes are the only fruit that doesn't float. (Banana was cut and was stuck to fit into the graduated cylinder.

Analysis

After conducting this lab and looking at the data I can easily claim that there is no correlation between the fruit’s nutrition and it’s density. My evidence for my claim is shown in the Data when grapes, the most dense fruit, have the most iron, but pears, the second most dense fruit, have the least amount of iron. Another example from the data is orange, which is the least dense fruit, has the most calcium but grapes have the second most amount of calcium despite being the most dense fruit. My reasoning for this is because this trend doesn’t show up for just one or two, it is shown in all graphs so it isn’t just for a certain nutrient, it’s for all of the tested ones.

Conclusion

In the end my original hypothesis was proved incorrect, the lab proved that there is no correlation in the fruit’s density and it’s amount of nutrients. The purpose was achieved overall. If you are looking for a healthier fruit to eat, you can get that from looking at the data, you can also find fruits with less sugar then others in the data.

Sources of Error and Inaccuracies

1.

When getting the volume of the fruits, I didn’t measure my hand’s volume so it was added to the fruits that floated, making the volume higher then it should be.

2.

I didn’t refill the graduated cylinder after each fruit, I only refilled it after every few tests.

Improvement

Measuring the Volume measurements could be improved accuracy wise. It could also have been better if I had gone into more specifics for example using Granny Smith’s apples as well Brae burn’s apples.

Application

Even though there is no correlation, some fruits have more of a certain type of nutrients than the others. If you are looking for a fruit that has a decent amount of every nutrition then eating an orange would be the best, it isn’t he lowest in any category and is the highest in calcium. If you’re looking for something high in iron then you should eat grapes, banana’s for magnesium, and oranges for calcium.
