Aim
My aim was to find out form of acid rain will affect the plants.

Hypothesis
My hypothesis was that the bleach and chemical experiment will destroy the plant because if bleach herms our skin it will defiantly destroy the plant.
I also think that tap water will come first because their more us to it.

Method
get a spray bottle
Fill the bottle with your liquid
Get your plant
Spray your plant at 3:00pm
Take a picture and repeat for a week

How Is Acid Rain Formed
rain is formed when water from the sea evaporates and air particles rise up this is called transpiration which forms condensation which form condensation clouds perspratoin when it rains it’s called precipitation

Results
Coca cola was 1st
Lemon was 2nd
control was 3 ( tape water)
Laundry detergent was 4th
Detergent was 5th

Research
Nox +ho2= NITRIC ACID
So2+ H20=sulfuric acid

Conclusion
My hypothesis was half right. The Chemicals experiment did come last but I was surprised about the tap water experiment .

Application
I think this will have an positive influents on locals the are incrested in plant grow but don’t have an professional advise to.
It will also help people to kwon what not to do near plant.
