The orange has become the most commonly grown fruit in the world. Orange juice is also the most consumed fruit juice worldwide, mainly because of its nutritious benefits, particularly high Vitamin C levels. It has a great deal of history and has been used for a number of purposes dating back to the Age of Discovery. One of these purposes is being used in medical and science experiments. It is featured in the following experiment, which focuses on the relationship between an orange’s size and its percentage of water. Key questions that will be answered in the experiment include: What is an orange? How do oranges “work”? Where do oranges originate? Why do some contain less water than others? These results can be useful to many individuals and institutes, including food shelters, parents feeding their children, or scientists performing experiments. …show more content…

We will compare which one has a higher percentage of water inside. The dependent variable is the water and the independent variable is the group of oranges. The first step is to gather all materials, including the two groups of oranges, tin foil, a knife, two sources of light (such as a lamp) and a weight scale. Begin by slicing the oranges into thin slices, weigh them individually and together as a group, and then place the slices onto tin foil beneath the lamp to start the drying process, also known as evaporation. Wait 24 hours, take slices off the tin foil and weigh the slices again individually and as a group. Compare them to the first time weighed and subtract to find the amount and percentage of water evaporated from the oranges. The experiment is now

Rhubarb Osmosis Lab Report

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

Salt Water Hydration Lab Report

743 Words | 3 Pages

These results were worthwhile as it can be useful to assist high-intensity endurance athletes to maintain peak performance through hydration. In these events, liquids are not readily available so it is useful to know which liquid evaporates the slowest so that they can get the most out of a liquid, and hence the hydration out of that given drink, in this case, it is Salt Water. It's also useful to assist people when exploring deserts or hot countries like Australia. In hot climates, liquids evaporate faster as more energy is present. This experiment is useful for tourists, so that they know to stay hydrated and make sure they are always covered in any situation in the areas of hydration.

Magnesium Sulfate Heptahydrate Lab Report

478 Words | 2 Pages

This heating and cooling was repeated until there was very little (less than 0.0010 grams) fluctuation in numbers. Vial one had a start weight of 14.7681 and an end weight of 15.4098, meaning the mass of the water was 0.4658. Vial 2 had a start weight of 14.7451 and an end weight of 15.3833, meaning the mass of the water in this sample was 0.4633. The mass of the water was found by subtracting the mass of the vial with the hydrate (the start weight) from the mass after the final heating (the final weight). To then find the percent water divide the water mass by the hydrate mass and multiply by 100 since the number is a percent.

The eggs were placed in the solutions, charting the change in weight after 15, 30 and 45 minutes; handling the eggs carefully each time and wiping off any excess water to avoid a misread by the scale. It is necessary to remove the egg and weigh individually each time to get the most accurate results. After the experiment was done, the eggs were placed back in their containers and the solution discarded of. It is imperative not to put the solution back in the containers.

Lab Report: Diffusion And Osmosis

We zeroed out the scale and weighed all four potato cores at once and recorded the mass. We then put those potato cores into the beaker of 75 mL of solution. With the potato cores in the beaker we then put a watch glass over the top of the beaker to minimize the amount of solution that evaporates. We let the potato cores sit in the solution overnight. The next day we then emptied the beaker of the solution by carefully draining the solution, while not letting the potato cores fall out.

Essay On The Effect Of Temperature On Osmosis

1159 Words | 5 Pages

For this lab I will be using water and sucrose to demonstrate the rate of osmosis. In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.

Osmosis In A Potato Cell

1598 Words | 7 Pages

By using the same mass of potato slices and putting them in different concentration of solutions for a specific amount of time will tell us how the concentration changes the mass of the potato slice. Therefore changing the rate of osmosis. Hypothesis: I predict that, if the piece of potato was put into a solution that has a high concretion of sucrose then the potato slice would lose mass as it would lose water from its cells because the water is moving out of the cell from a high concentration to a low concentration of water through a semi- permeable membrane. The cell is hypotonic and the solution is hypertonic.

The hypothesis we came up with for this project was that in the distilled water there wouldn't be no change in the potato, we wouldn’t see a gain or loss with the water sitting in the beaker. The beaker with the 30% Sucrose and Distilled water we predicted that there was going to be weight gain to the potato. And for the distilled water with the 30% sucrose and we predicted weight loss. But the results came out to be the first bag content being isotonic the second bag came out to be hypotonic and lastly the result came out to be

How Does Acid Rain Affect Plant Growth

1186 Words | 5 Pages

 Two of the same types of plants were used, in order for the results to be reliable.  One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed.  The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3)  The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0)  Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one.  The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice.

Water Potential Osmosis Experiment

743 Words | 3 Pages

This conveys that sucrose concentration shall affect water potential, therefore the higher the sucrose concentration, the lower the water potential. This is how osmosis is linked to water potential and why experiments testing osmosis can be used to create methods to find and/or test water potential within plants. In addition to this, concentration of sucrose in a solution and in a plant cell or plant tissue shall have an effect on water potential.
