Density Related to Nutrition

Improvement

Observations

The experimental idea would improve if it had happen to have vegetables as well as fruits and different varieties of them because then the results would go more in depth to what would happen if the scenario was with vegetable. The experimental design can also improve if fruits that are not necessarily common and different (and also changing the 1000 ml graduated cylinder), so the results can vary and show the world more of the different kinds of vegetables and fruits available that will entering our bodies.

Conclusion

Contradicting with my hypothesis, even If a Fruit makes you feel full and gives you energy, that does not mean that it does not have enough nutrients like the rest of the fruits. It is the complete opposite because the denser the fruit is the more nutrient packed it is. In the claim it was stated that If a Fruit makes you feel full and gives you energy than it does not have an adequate amount of fine essential nutrients then the more the fruit is dense the less nutrients. Throughout this experiment and also represented by the data and the calculations everything said in the hypothesis was indeed contradicted in this experiment in more then one ways.

In the beginning of the experiment the claim was that If a Fruit makes you feel full and gives you energy but does not have an adequate amount of fine essential nutrients then the more the fruit is dense the less nutrients are available in the fruit because more density makes fruits have less essential nutrients. When doing these experiments they were some trends that were standing out more than others that partially contradicted with the experiment. Some of them were that when a fruit looked physically bigger and was more than likely that it would weighed more than the fruit that looked smaller, but more than once both fruits weighed their weight was relatively close and. The second trend was that even though some of the fruits were taking up volume in the graduated cylinder they did not weigh as much as the ones that did not take up volume. Another trend that was shown that the apples were heavier in weight in general, the more everything in the chart increased so the fruit density is probably going to be higher. When it comes to trend number two is easily proven by the manipulated data because when comparing the volume and the fruit mass you can see that there is a difference in the weight and volume of the fruits. Corresponding with the manipulated data, this proves the trend number three because the density of the apple at the end as a average ended up being higher than the oranges, because the apple had 0.187 density while the orange had a 0.086 density. Also when the percent of change was done with both fruits, like density, the percent of change from the volume of water and the volume of water and fruit ended up being higher for the apple by almost 0.092%. For trend number one, the statistical analysis (which was a bar graph and a error bar) and the manipulated data proves it right because it the data shows that the two similar fruits, whether it is oranges or apples, even if they don't like they could be the same weight they end up right around the same weight for example in the data for apples, one of the apples weighed 75g and the next one look nothing like the one before and weighed the exact same. The scientific reason behind these is the law of density, fruit density because they affect the fruit from looking different from what it is on the inside.

During the experiment when weighing that apples and the oranges it had appeared that even though even though, considering look wise the orange was bigger than the apple, when it came too the actual weighing time of the two fruits, the apple had weighed much more. Sometimes when a fruit looked smaller it actually weighed more than the fruit that looked bigger. When filling in the graduated cylinder, sometimes it was not filled right, for example it went from either being over filled or to not having enough water available inside.

Application

Sources of Error

This experiment applies to the real world because from this people can see or realize how the shape and size of the fruit does not matter but what is inside. This also applies to the real world because this is something that every person must have gone through in their lives...not knowing exactly what they are eating. From the results of the experiment, this can be useful because now if not yet, people can understand not only how the fruits look or size does not matter, but also how this should provoke them to keep an upon their eyes upon what they eat is not necessarily what they think is going into their bodies and what is being processed.

When doing the experiment the graduated cylinder was not always filled properly so this might have changed the data when measuring the fruits submerged in the water. Also the graduated cylinder became too small for the apple so the apples were squeezed in for them to fit inside or cut, and in so doing changing the shape of the fruit. When weighing the mass of the fruits, sometimes the food weigher would stop working in the middle, and having to reset it so many time might also have been a source of error or Inaccuraciey.

Procedures

Variables

The Dependent variable of this experiment is the nutritional value and the Independent Variable is the density of a fruit because the nutritional value dependents on the density of a fruit. The experimental group of this experiment are the fruits since they are the ones that are being measured and put in a graduated cylinder full of water The control group is nothing since this a comparative experiment. The constants that need to be held constant in order for a fair trial are the graduated cylinder being filled half way through, and the scale/ ruler has to be in grams. Another constant that needs to be held constant is throwing the water away after using a different kind of fruit because it might affect the density sometimes.

1. Put aside the oranges and apples too sample aside for a moment

2. Using the internet, past background information create a chart/table for each fruits nutritional value (should also find mass of the fruit, and make sure to fill this information in on the chart to use for later in the experiment instead of calculating Mass of the fruit)

3. Convert (if needed) each of the fruits weight into grams

4. Place the 500-1000 ML graduated cylinder on a flat surface

5. Now fill the graduated cylinder 1/2 way through

6. Record the volume of the water that is 1/2 way through, down on paper or notebook

7. Place the apple into the graduated cylinder so that is fully submerged in water

8. Measure the measurement of the apple and water

9. Record this information down

10. Repeat steps 7-9 for the remaining 49 apples

11. Now throw the water away, used for the apples

12. Repeat steps 5-10 for oranges now

13. From the weight and object submerged in water measurements calculate: Volume, Mass (should already have this from research) , Density of the Fruit

14. Compare all of the densities too the nutritional value that's in the table made earlier in step 2

15. Choose 5 nutrients found in both apples and oranges

16. Create a graph comparing food density and nutrient content using the Bar graph and the error bar (should graph the food density average of all trails)

Materials

• 50 apples (skin)

• 50 oranges (no skin)

• Measuring Ruler/Scale-----Should be a food scale (g)

• 500-1000 ML graduated cylinder that has a wide mouth (Big enough to fit the fruits)

• Water (an adequate supply)

• Lab book or paper too note down data

* Apples will have skin on them because the skin is edible and nutrients are available in them

* Oranges will not have skin on them because the skin is non-edible and the nutritional value will not be affected

Hypothesis

Problem

If a Fruit makes you feel full and gives you energy but does not have an adequate amount of fine essential nutrients then the more the fruit is dense the less nutrients are available in the fruit because more density makes fruits have less essential nutrients.

When you eat a fruit that seems to make you full and gives you enough energy, but does it have an adequate amount of fine essential nutrients? And the fruit that does the opposite and does not make you feel full have the same or less amount of the essential nutrients and how is this all related to fruit density?

Research

Research

Nutrient Density

• Nutrient density, means it's how much you get out of one thing when you are given presence of something else.
• So in the case of nutrient density the “things” you get out of one thing are the nutrients.
• This helps you get concentrated amounts of valuable nutrients such as Vitamins, fibers, and essential fatty acids and some phytonutrients which are nutrients that prevent diseases and promote good health.

Nutritional Value/ Label

• The Nutritional Value of a food defines what the product is made up of and also what the impact is on the human body.
• This also relates to cholesterol, fat, salt, and sugar intake. Nutritional value can be used as a tool to understand a particular food before consumption.
• The nutritional value is actually on a nutrition label.

Potassium in Fruits

• This mineral is almost found in any fruit and vegetable we can eat, which is really good because then you get a very important mineral in your body.
• This mineral is very important for a healthy nervous system and a regular heart beat.

Purpose

The purpose of this experiment is to see if a fruit, that is depending on the density, will have more or less nutrients inside itself.

Fruits

• Most fruits are low in fat, sodium and calories, and none have any cholesterol.
• Fruits have very important because they have the essential nutrients that are mostly under consumed (without fruits) which include potassium, dietary fibers, vitamin C, and Folic acid.
• Some fruits with sources of potassium include: bananas, prunes, dried peaches and apricots.

Density

• Density is how much a material has for a given volume, it is like a plastic sponge.
• We always use density as a standard for density ( water has a density of 1).

The formula for density:

D= Density

M= Mass

V= Volume

D= M/V
