Weedbuster Investigations

Seed Transport

Aim:

To investigate how seeds move from one place to another. Hypothesis: (What do you think will happen?)

Equipment:

  1. An old pair of socks!
  2. A3 sheet of white paper
  3. Stopwatch
  4. Magnifying glass

Method:

  1. Go to a grassy/scrubby area and put your socks on over your shoes. Walk around the area for one minute.
  2. When your minute is up, stop walking and carefully take off your socks and turn them inside out.
  3. Take your socks back to the lab (classroom!) for examination. A magnifying glass will help here.
  4. Pull off any seeds and group them by size, shape, colour. Count the number of seeds you found and record the details on a chart. (You could graph these findings as part of the results section)

Results:

"We found ."

Conclusion:

"My hypothesis was .because the results showed."

# Write up your own investigation!

Choose from one of these ideas or make up your own.

  1. Are seeds transported by vehicles? (take samples from car mud flaps!)
  2. Are seeds found in the soil? (take soil samples and look for seeds)
  3. Do weed seeds have special shapes that help to transport them? (you could look at their different features with a microscope!)
