Understanding Food Chains and Ecosystems

The video tutorial introduces preschoolers to the concept of food chains, focusing on tide pool ecosystems. It begins with a discussion on the basic needs for survival: sun, water, and food. The teacher explains photosynthesis, highlighting how plants make their own food. The concept of food chains is introduced, emphasizing the role of green plants. A hands-on activity demonstrates a tide pool food chain, using phytoplankton, mussels, and sea stars. The video encourages children to create their own food chains using sea creature toys or cutouts, fostering creativity and understanding of ecological relationships.
