Statistics on leaves in the Botanical GardenThe starting point is the following question: is there any precise, mathematical relation between the length and the width of a leave? In order to discover the truth, you have to pick one type of plant and answer these questions: 1. What is the name of the plant? ..

2. What is its scientific name?.....................................................................

3. Take a photo of the leaves Does the leaf have any type of symmetry?...............................................

4. If it does, what type of symmetry? . How many axis? 5. Does it bloom?

6. If yes, how many petals does the flower have?..............Is this a Fibonacci number?...........

7. Find as many data about the plant as you can and write them down:

8. Measure the length (l) and width (w) of ten different leaves of the same plant and calculate the ratio l/w. Fill in the table below. LeavesLength (l)Width (w)Ratio l/w

9. For the ratio values, calculate the mode, the median, the mean and the amplitude. Draw a bar chart or a graph for the l/w ratio over the number of leaves. Mean =Mode =Median =Amplitude =
