Aim: To find out how important sunlight is for the plants.
Hypothesis: The amount of sunlight there is affects how much starch is there in the leaf so I think the leaf with sunlight will have starch but the one without will not have any starch
Variables:
- Dependent: Rate of photosynthesis (Use identical plants)
- Independent: Amount of sunlight given ( Put one under the sun and cover the other one with black plastic bag)
- Controlled: The conditions (Temperature, water, minerals, Humidity, light and controlling pest) We can manipulate them by putting the plants on the same place and using same soil)
- Uncontrolled: Weather, quality of equipments, Temperature of the room.
