How does the wing-like structure helps in seed dispersal?
Hypothesis: The presence of wing-like structure allows a seed to stay afloat in
the air for a longer period of time before reaching the ground.
Description of activity:
1. Prepare 2 seeds with wing-like structure from the same plant
(e.g. Shorea fruit)
2. Remove the wing of one seed (Seed 1)
3. Stand at an elevated platform (e.g. a chair) and dropped Seed 1 at
shoulder level.
4. Note the time taken for the seed to reach the ground in the table below.
5. Repeat Step 3 three times and take the average timing.
6. Repeat step 3 to 5 for Seed 2.
7. Conclude.
Time taken 1
Time taken 2
