Light works
A boy put some seeds in pots. He
covered them with soil. 'Don't be silly,' said his friend, 'plants won't
grow in the dark.' Who was right?
Plant some seeds that grow quickly and easily - like nasturtium or quick-growing
brassicae - in yoghurt pots filled with good soil.
Try four different tests:
 |
On the surface of the soil and in the light. |
 |
On the surface of the soil and in the dark. |
 |
Buried in the soil and in the light. |
 |
Buried in the soil and in the dark. |
|
  Water
all four. Keep the soil moist, but not wet.
Keep a written record of what happens over the next few weeks.
|
- Now write up what you found out. Make sure you
include any conclusions about seeds sprouting and plants growing.
