This document provides instructions for an experiment to observe how plants drink water. Students will place white roses in cups of colored water to see how the water travels up the stem. The objectives are to understand what plants need to grow healthily, learn that plants need water, and observe capillary action. Capillary action allows water to move through narrow tubes in the plant, carrying water from the roots to the flowers.
3. Objec
tive
1. To know how to conduct an experiment, observe
closely what is happening and keep appropriate records.
2. To understand what plants require
grow and staying healthy?
3. To learn that
plants need water
to stay healthy.
18. 2. Put the plastic cup on the table.
3. Pour the water mixing the coloring
food into the 4 plastic cups: each of
plastic cups will have colored water.
The first 2 plastic cups will have blue
water. The other 2 plastic cups will
have red water.
19. 4. Put a rose into a plastic cup
containing water mentioned earlier.
5. - The first rose will be in blue water.
- The second one will be in red water.
- And the last one will be in both blue
and red water.
22. Flowers drink water with a capillary
action. Capillary action happens when water
molecules are more attracted to the surface
they travel along than to each other. In paper
towels, the molecules move along tiny fibers.
In plants, they move through narrow tubes
that are actually called capillaries. Plants
couldn't survive without capillaries because
they use the water to make their food
