Lets Think About...Plants
Activities:
4. Inside a Seed, A Plant Is Ready To Grow
Take an avocado pit.
Place a few tooth picks securely around the diameter of the avocado.
Place the avocado supported by the toothpicks in a narrow jar.
Be sure the pit is suspended and the point is facing upward.
Add enough water to jar so that half the avocado pit is under water.
Place where there is sufficient sunlight.
Watch over time as the avocado sprouts its leaves and roots.
Get some Lima Beans. Lima beans are large and grow easily.
Soak beans over night. Fill a clear jar with wet paper towels.
Carefully place lima beans between paper towels and the glass surface.
Be sure beans are visible from the outside.
Avoid the bottom area of the jar.
Place where there is sufficient light and keep damp.
Beans will begin to grow within a few days.
Observe and comment on what is happening.
Once beans are fairly well established, move plants away from the light source
and watch as the plant reaches toward the sunlight,
5. Most Plants Grow From Seeds, Some Plants Grow from
Roots and Stem
Suspend a sweet potato or yam in a jar filled with water.
Use toothpicks around the diameter to support the sweet potato.
Put water in the jar and place near a window.
Watch how the plant begins to grow.
Both roots and leaves will emerge over time.
