Photosynthesis Concepts and Processes

The video introduces second graders to photosynthesis, explaining how plants make their own food using sunlight, water, air, and soil. It highlights the role of chlorophyll in giving plants their green color and producing oxygen. The video also discusses the similarities in photosynthesis for indoor and outdoor plants. Students are encouraged to explore plants and complete a worksheet activity to reinforce their learning.
