This activity is a fun way for children to learn about flowers and how they drink water. It requires just a few items: water, clear cups (available at the Dollar Store), food coloring, white flowers, and scissors. The first step of this project is to trim the flower stems, to shorten the time it takes for colored water to reach the petals. Fill each clear cup with water, and add a few drops of food coloring. Finally, invite children to take turns placing flowers in each cup.
Observe the flowers later that day, or even over the next few days, to see how the colors of the flower petals change. If you work with older children, you might invite them to record their observations on paper, by drawing pictures of what they see. As children make their observations, talk with them about how the flowers are drinking the water.
