– Glass

– Copper

1 Measuring Cylinder

1 Measuring Jug

1 Can With A Spout

Water

Method.

Step 1.

Measure the mass of the first material using a balance and record the results onto a results sheet.

Step 2.

Pour water into the can until it is level up to the spout.

Step 3.

Place the material into the water filled can. Once submurged some of the water will be displaced and will pour out of the spout.

Step 4.

Collect the displaced water in the measuring cylinder and measure the volume, record this value.

Step 5.

Repeat test for all other materials on the equipment list.

Step 6.

Calculate the densities* and write up the results in the table ready for analysis.

*Scientific Note.

To calculate the density of the materials, I had to use the following calculation :

Density = Mass

Volume

Designing an Osmotic Potential Experiment with Potatoes

Osmosis is used throughout the kitchen in various countries. In France, aubergines and cucumbers are often soaked in salt to create a nicer texture, however chefs lack understanding of why this happens, as they would have forgotten about it after they finished school, they only know that it happens. Therefore, this experiment is designed to explain to the millions of chefs around the world why the water is “sucked” out of a vegetable when it is dipped into a salt or sugar solutions. I believe that having knowledge over the reason for something can open up new ways of thinking; this is why I think it is so important to explain the reason behind this phenomenon. Famous chefs are also known to be under time pressure; for example, every cooking show on TV includes some sort of time pressure scenario, weather it is a ticking clock or waiting customers. For...

Investigating the Effects of Salt on Seed...

PROBLEM/RESEARCH QUESTION In this investigation, we are researching and investigating whether the concentration/percentage of NaCl (salt) in water affects the germination rate of seeds and if so, which concentration germinates the most seeds. We will formulate our research by conducting an experiment in which we will observe the germination of seeds in various concentrations of salt water and evaluate the results gathered. In particular, we will measure the percentage of seeds germinated in one week and formulate our conclusions from there. HYPOTHESIS I hypothesise that the highest percentage of seeds will germinate in the petri dish that contains the lowest percentage of NaCl in water- 0.5% salt salinity and the percentage will decrease as the percentage of salt in the solution increases. I predict this because I know from prior knowledge that seeds need to be able to absorb H2O to germinate and salt prevents this. So if we increase...

Investigating the Effect of Sodium Fluoride on...

Graph Showing the effect different volumes of Sodium Fluoride has on the average rate of production of H+ ions as measured by the colour change of resazurine Comment on Graph: The graph depicts a positive trend, as the amount of Sodium Fluoride increases the average rate of H+ ions as measured by the colour change of resazurine also increases. This increase is consistent with each 5 mL increase of Sodium Fluoride resulting in an increase of one assigned numerical colour. This steady increase plateaus at 15mL with no further colour change. Conclusion and Evaluation Conclusion In our experiment we tested whether changing the amount of Sodium Fluoride effects the rate of respiration as measured by the colour change of resazurine. Our experiment indicates that there is a relationship between sodium fluoride and the rate of respiration. In our experiment the more sodium fluoride that was added the less colour change,...
