Teach students about the root structures of plants by germinating a seed and viewing its roots. Fold a thick paper towel in half and soak it in water. Place a seed or a bean into the center of the folded paper towel. Insert the folded paper towel into a plastic bag, and seal it shut. Place the bag in a sunny location. After three weeks, take out the paper towel and inspect the sprouted bean's roots. You will be able to see the small off-branching that allows the plant to absorb nutrients and water from the soil.
Students learn about the anatomy of a plant by creating a diagram of a flower's parts. Cut out root shapes from white construction paper. Make a long rectangle from green construction paper. Form two leaf shapes from green construction paper. Make flower petals from red construction paper, and cut out a flower center from yellow construction paper. Place a sheet of white paper onto a table; paint the bottom third of the paper brown. Paint the rest of the paper light blue. Allow the paint to dry. Glue the root shapes onto the brown paint. Glue the green rectangle sticking up from the roots. This will be the stem. Glue the two leaves onto the stem, and glue the flower center at the top of the stem. Glue the flower petals around the flower's center.
Planting a seed can teach students how to tend to plant life in order for it to thrive and grow. Start by filling a pot with potting soil, and insert a single seed into it. Cover the seed with more soil, and press the soil down gently. Water the soil well, and place it into a sunny window or outdoors. Water the pot daily for two months, and make sure that it is receiving enough sun. The plant will grow from the seed if it has enough water, light and nutrient-rich soil.
