Acid rain

Acid rain is formed when factories burn fossil fuels and let the gas up in thew air through big tubes, the gas combines with clouds which makes the clouds heavier, then the acid rain can harm trees, dissolve buildings, make water toxic so you cant drink it, and it can kill fish. or it can just kill land. it ruins the environment

Petri Dish Experiment:

Aim: To observe effects of Acid Rain, 

Method: in a petri dish place items around edge. Wet dry ingredients with drop of water.. In the middle put a weigh boat. add a spatula of sodium sulphate into the weigh boat. and 5 drops of sulfuric acid. Quickly close the lid.

Hypothesis: I think that the acid will destroy all of the items and completely dissolve them so there is nothing left of it apart from the acid. the ingredients are, Petal, Calcium Carbonate, Apple, Universal Indicator, Bromothymal Blue. we added a spatula of sodium sulphate into the weigh boat.

Here are the photos of the results, The universal indicator went a light pink and the Bromothymal blue went a gold/green/yellow colour. the calcium carbonate just went clearer
