Find Out How Plants Use Water

In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers. Use this activity to discuss the structure of plants and the nutrients they need to survive. Safety note: young learners should get an adult to help them trim the stems of the flowers.
