Our Science unit this semester has been 'Pollution'. We have learned all about Land, Air, Water, Noise & Light Pollution and the consequences each of the forms have on our planet. Students have been so excited, as every lesson I've tried to incorporate a practical experiment or investigation for them to work on. The photos above are of our experiment that has continued over 10 days. Each group planted grass seeds in 3 tubs of soil. Then, watered one tub with tap water, of pH 7, one tub with full acid water and one tub of water with 1/2 tap water and 1/2 Acid water.
The effects can be seen above. The first one is obviously the tap water. The middle one is the acid water.
So, acid rain has a frightening effect on our planet - not only can it dissolve buildings, statues etc, it has a ghastly effect on the rate of growth and quality of our plant life.
