I plan to see if the body size of an animal affects its heat loss. I am going to do this by using three glass beakers with various amounts of boiling water in them. I will then see which beaker looses its heat the fastest or the slowest. Prediction I predict that the smaller the animal the faster that it will loose its body heat so I predict the smaller beaker will loose its heat the fastest and the largest one will loose its heat the slowest. The science I predict this because for...

If I was to repeat this investigation then I would stick the data loggers down to the beaker so that they do not come out of the water. I would also repeat the experiment 3 times to be more accurate and I would also include a 400ml and a 50ml amount in the experiment. By doing this I would have found out more information and made my results more accurate.
If I had more time then I would research the sizes of animals in different climates. This will have made me surer about my conclusion.
Investigation For this experiment we plan to investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato core of a given size. Osmosis is defined as the net movement of water or any other...

Prediction I predict that the higher the concentration of salt, the lower the mass the potato cylinder will become. This is because there is a greater concentration of water molecules inside the potato cylinder, so the water will drain from the cylinder by osmosis, to where there was a...

Prediction Osmosis is defined as is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. In a high concentration of water the amount of solute e.g. sugar is low. This could be called...

I will measure the volume of gas produced as the catalase in the potato tissue reacts with the hydrogen peroxide to create water and oxygen. I will change the temperature at which the reaction takes place, but to make the test a fair one I will keep the pH level...
