Sycamore trees have wings on their seeds. Design an investigation to examine the
effectiveness of the wings as an aid to dispersal of the sycamore seed.
Use the following headings explain:
How would you plan to measure ability of wing to aid dispersal?
Name any variable in this investigation.
What data would you need to collect to test if the wings do help the sycamore
seeds to disperse?
How can you use the data collected to verify if the wings are an aid for sycamore
seed dispersal?
