B3: WHAT AFFECTS THE LEAVE SIZE OF IVY?
AIM:
To take ivy leaves from the North and South side of a hedge to come to the conclusion of what natural factors will effect the ivy leaves and why.
THEORY:
The main factors that will affect the ivy leaves are how much sunlight the ivy gets, which I will be concentrating on in my investigation. Industrial factors would affect the ivy but the hedge we are taking them from this would not have any noticeable affects.
PREDICTION:
I predict that the ivy leaves that have more sunlight will be of a smaller size because if they get more sunlight they don’t need as much energy that is taken from the sun. Meaning that they have a smaller leave surface area. Some people might think that if they get more sunlight they will be larger because it is easier to get energy from the sun and that it can grow bigger with the energy it gets from the sunlight. I also think that the ivy leaves that are in the shade most of or all the day will be larger because they do not get as much energy from the sun as the ones on the other side so it they do ever get sun light they will have to be bigger so they can take in as much energy as possible. Other factors which might affect my results is the kind of tree the ivy has grown up because of how much nutrients and minerals it is getting from the ground. I will prevent this from interfering by taking it from the same area on the hedge. Also any small or bigger animal that are living on the ivy may affect the size because if they eat the leaves the size will differ for each one because there will be holes which will reduce the surface area.
