In this experiment, caffeine was used to determine the increase in heartrate, when increasing the amount of concentration. Caffeine was used on a water flea known called daphnia, to see the outcome. The results show that an increase of caffeine concentration increases the heartrate of the daphnia. This was tested by the daphnia being observed underneath the microscope. This technique was shown to be an effective way of analysing the heartrate, this would mean that the same effect is also opposed...

I chose to investigate the different concentrations of caffeine on the heart rate because I wanted to see how it impacts the human heart when the concentration of caffeine is increased. Does the heartbeat stay consist, drop, or increase?  I hope to find out that with an increase of concentration given to the daphnia the rate of the heartbeat should also increase.

Radiation is used every day in the UK, it is used for different purposes such as medical, industrial, research and communication. Some of these can potentially be harmful when exposed, which must be controlled effectively. The health and safety Executive (HSE) regulates the work which exposes radiation to workers, the public or both.

Medical physics is the application of physics to medicine or healthcare, using the physic concepts, theories, and methods to help screen, diagnoses, or treatment. Radiation is used in medical application, which is an energy that transfers from one place to another in the form of a wave or particle. There are two types of radiation, ionising and non-ionisng.
