Materials Required:
Large sheet of chart paper
Markers or colored pencils
Images or drawings of sea life (optional, for reference)
Ruler (optional, for neatness)
Steps Involved:
Introduction: Begin by explaining the concept of food chains and food webs. Discuss how a food chain shows a direct path of energy, while a food web shows the complex interactions between multiple organisms.
Drawing the Chart: On a large sheet of chart paper, draw a circular food web featuring various sea life (e.g., plankton, small fish, larger fish, seals, sharks). Show how arrows connect each organism to illustrate the flow of energy.
Labeling: Label each part of the food web, including the different organisms and their roles (e.g., producers, consumers, predators).
Discussion: Engage the students in a discussion about the food web, asking questions to reinforce their understanding of how energy flows and how different organisms are connected.
Activity: Have students create their own food web diagrams on smaller sheets of paper, using the chart as a reference. Encourage them to include additional sea life and label their diagrams.
Review: Review the diagrams with the class, discussing any new insights or questions that arise.
