# 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.

Extracts from this document...

Introduction

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

Middle

Pencil to draw around ivy leaves.

METHOD:

1. I will firstly take five ivy leaves from each side of our chosen hedge. These will be taken randomly from both sides to make it a fair test.
2. Then I will draw around them on graph paper being careful not to mix up the ivy leaves from the North and South sides.
3. To then find the area of the ivy leave I will count up the squares inside the outlined leave made easier by the graph paper.
4. I will then add up all the total areas of one side and divide it by five to get an average leave area.
5. These results will be put in to graph to show then more clearly.

SAFETY AND HAZARDS:

1. Do not climb the trees to get the ivy leaves because of danger of falling.

Conclusion

GOOD AND BAD COMMENTS ON THE METHOD:

GOOD:

The experiment was very straightforward and I think that I have done the best possible method I could.

I also think that just drawing around the leaves was the most effective way to measure the ivy leaves area.

BAD:

It was very had to pick the leaves randomly and not to fix it to your prediction. To improve this I could do it with my eyes closed so not to see the exacted place they are coming from

The way in which I counted up the area of the leaves was perhaps not the best way to do it. To improve this I could do it in a different way like count every little miller metre square to make it more accurate.
