Dandelions in different places
Secondary | Environment | Views: 142
You will need:
- A piece of paper
- Different places where dandelions grow
- A homemade protractor
- A notebook
What to do:
- Use a piece of white paper and follow the instructions for making a homemade protractor. You can make it record only three measurements – 90 0 , 45 0 and flat, or you can make a more sophisticated scale – 90 0 , 67.5 0, 45 0 , 22.5 0 and 0 0 – the video shows you how.
- Go out into your local park and places near by and look for dandelions
- Measure the angle of the flower – if it is upright record it as 90 degrees, you can then use your home-made protractor to measure the angle. You can also record the size of the biggest leaf for each plant
- You might wish to make some drawings with labels. Can you find a pattern between where the dandelion was found the angle of the flowers, and leaves and the size of the biggest leaf?
- Why do you think some places have tall upright dandelions with larger leaves?
Health and Safety: Do not pick wildflowers and always wash your hands after being outside
