Students will participate in a skit to learn that plants make food through the process of photosynthesis.
- Images of the sun, water, and air (available in the "Teaching Tools" section of www.gotdirtwisconsin.org)
- You may choose to substitute props for the images
- Soup pot
- Large spoon
- Ask the students how they think that plants eat.
- Use humans as an analogy. Humans eat food to get energy. Have they seen plants eat food?
- Explain that leaves help plants make food through the process called photosynthesis.
- If humans could make their own food, it would be like making a piece of lasagna in their arm.
- Perform the following skit to illustrate what a plant needs to make food.
- Holding your soup pot and spoon, introduce yourself as Chef Chlorophyll. Tell your students that you live inside the leaves of a plant and are making food to help the plant grow.
- Taste the soup in your pot and explain, “It tastes okay, but it needs a few ingredients.”
- Ask the students what ingredients the plant needs to grow.
- Each time a student answers a correct ingredient (sun, air, and water) give the student the image of the ingredient and allow them to place it in the pot.
- Repeat until all of the ingredients are in the pot.
- Tell students that the soup tastes just right and now the plant can grow big and strong.
- Have students create recipe cards with what plants need to make food.
