Fair

2. Question
 How is rain formed
 How is acid rain formed

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

4. 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.

5. Independent Variables
 Position (on the bench)
 Lighting (in room before taken to school)
 Temperature (of the room before taken to school)
 The angle of which the spray was taken.
 Dependent variables:
 Growth

6. Materials
 An ice cream container (each=5)
 A spray bottle (each=5)
 A plant (each=5)
 A bench

7. 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

8. 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

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

11. My plant graph

12. Research
 Nox +ho2= NITRIC ACID
 So2+ H20=sulfuric acid

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

14. 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.
