In Biology, we have learnt how to use the Chi-square test to determine whether there is a significant difference between data, and if a null hypothesis was collected. It seemed appropriate to apply this aspect of what we had learnt to our group’s investigation, as we would be able to determine whether there was statistical differences between any data we collected on biodiversity.

In ESS, we have performed a similar investigation into various abiotic factors and varying plant species along a transect, using the Simpson’s Diversity Index. By using quadrats, we identify the specific points at which we take recordings. This means that at each point that we place the quadrat (for example 1m between each), we know that we should take measurements of pH and count how many different species, and the abundance of each, we see, in order to more efficiently measure biodiversity.

In Chemistry, we practised using pH metres in order to test the amount of proton ions in solutions. This was used in this project; by mixing a fixed amount of soil in a zip lock bag and creating a solution with a standard amount of water, we were able to examine the acidity of the soil.
