Students in Stage 1 are learning about living and non - living things. Plants are living things and students have been investigating how plants grow.
Stage 1 students have conducted an experiment to investigate how and why plants need nourishment to grow. Using their roots, flowers "drink" water up into their stems, leaves and flowers to make food. Eventually, the water evaporates from the plants, much like human sweat. This is called transpiration. Even cut flowers without roots can do this! More water is pulled up from below to fill the empty space left by transpiration.
By watching the journey of harmless food coloring through the stems of flowers and celery, we can see all the places water goes in a plant!
