What are the steps for seed dispersal by dropping fruit?
1) Get yourself some fruit containing seeds . you can compare ones from different dispersal mechanisms. 2)Decide on a fixed height to drop the fruit from 3)Drop the fruit one at a time 4) Using tape measure, measure and record how far along the seeds have been dispersed 5) Then find the average distance each type travels
How many times do you do this?
atleast 3 times
What do you need to keep the same to keep it a fair test
the person dropping the fruit the height the fruit are dropped from the place you’re doing the experiment
What can you use to investigate the ‘wind factor’
a fan
What are the steps for investigating the wind factor
1)Set up the an at a fixed distance from the person dropping the fruit 2) Switch the fan on - needs to be set at the same speed for every fruit you drop 3) Drop the fruit as before and measure how far along the seeds travel
