=Ideas for Biology about what to do about water:=

We could do a similar experiment conducted at V-Resort:

> Your task is to compare the organisms found living in two rivers to conclude which river is the most pristine / in better health / least disturbed by human activity.
 * **TASK:**

This was the biology experiment (comparing the health of a river), however if we are working at West Lake we could compare the health in two different places and see how the location effects the pollution. (for **e.g.** compare the health at the edge of the river compared to the middle)

the only limitations are that it will be hard to reach the bottom of the lake (as it is pretty deep).

We can use **diversity indexes** like we did in V-Resort to anaylse the data and compare the two parts of the river (if that is what we are planning to do)

I don't know if this would work - if there would be enough time - but we could look at how plant growth is affected by the area it grows in. So we could take the soil from West Lake and the soil from somewhere else and we can plant two fast growing seeds and see which germinates first.

This experiment kind of follows a similar idea: []

__

=**Research Question #1:** How does water pollution in West Lake (//specific area to be mentioned later)// affect pH levels?= = =

For this experiment we will need (//equipment mentioned ont he __Equipment Page__)://

 * ======pH probe (or/and litmus paper, because then we also have a physical result which we can photograph and put into our presentation)======
 * gloves and boots
 * computer (to upload the data)

===**Hypothesis:** //IF// our knowledge about West Lake is true and West Lake is polluted //THEN// the acidity levels will be higher //BECAUSE// the more polluted a substance, the more acidic the pH levels will be.===
