Experiment 16
ACTION OF HEAT ON PLANTS
MATERIALS: 2 small plates, cotton wadding, radish seeds, water, a glass.
- Put quite a few radish seeds in a glass with water and leave it for 24 hours.
- Pour out the water and then take the two plates and cover them with the cotton.
- Scatter the soaked radish seeds on top of the cotton and water both plates well.
- Leave one plate in the classroom and put the other in a refrigerator.
- Keep both well watered.
- Observe them each day and write up your observations.
Experiment 17
ROOTS ALWAYS GROW DOWNWARDS, AND THE STEM?
MATERIALS: A glass, ink-blotter paper, black construction paper, a rubber band, sand, bean seeds, water.
- Cut the ink blotter paper to fit around the inside of the glass.
- Place the bean seeds between the blotter paper and the sides of the glass making sure they are positioned differently.
- Then fill the glass with sand and wet sand.
- Cut the black construction paper large enough to wrap around the outside of the glass, holding it in place with a rubber band.
- The sand must be kept wet.
- Do the same using other seeds.
- Observe your glass every day.
- Observe what happens and write your observations.
Experiment 18
ROOTS ARE SENSITIVE TO WATER
MATERIALS: a clear container, wide and straight-sided, radish or bean seeds, soft soil, a watering can and water.
- Fill the glass container with the loose soil.
- Plant the seeds in the soil close to the glass sides and water the soil well where the seeds were sown.
- After the roots have developed well in depth, begin to water increasingly farther away from the plants.
- Observe the container every day and write your observations.
