We checked if the seeds can grow in diferents concentrations of different polluting water (in distilled water, polluting 0.1M, polluting 0.01M and polluting 1M) . The pollutings are: NaCL, NH3 and NaOH.
We did this experiment:
We took 10 ml of the polluting solution and put them in a 100 ml test-tube.
We filled it with distilled water up to a 100 ml.
We poured this solution into a new bottle labeled "polluting 0.1".
We maked this procedure with the other pollutings.
We put paper in every petri sheet.
We placed 10 seeds in every sheet.
We put 15 ml of every concentration in every sheet and wait a week.

We learn about the pollution of the citys. In the city there are a lot of cars,motocicles, factorys which make a lot of pollution.
This photo is a natural landscape because there are any things that the human construction. Are a lot of mountains and a big lake with lots of fish.
