Easy
Experiments
1. In a tall
glass or jar, add food coloring to a couple inches of water. Now
take a stalk of celery with a fresh cut on the bottom and stick
it in the jar. With time you can watch the colored water move
up into the celery stalk. Capillary action and transpiration of
water from the leaves is actually pulling the water up through
the xylem (veins).
2. You may have
already stuck toothpicks in the side of a potato or the pit of
an avocado, placed it in a jar of water so it is half submerged,
then watched it grow. (Keep in mind that Avocados take over fifteen
years to bear fruit). Did you also know that you can cut off an
inch of the top of a turnip or a carrot and place it in a shallow
dish of water? Then the tops will start to push out new leaves.
3. Make a magnifying
glass in minutes. Carefully cut the bottom off a paper cup. Cover
this base loosely with clear saran wrap and put a rubber band
around it. With the cup upside down, pour a little water onto
the saran wrap and watch whatever is underneath it grow.
