Fitting Algae Into the Food Web
The food web you created in the food web game was one that is found in the Antarctic. As you might imagine, a food web in the tropics looks very different from the one you created. Environmental conditions (temperature, light, nutrients) are different in the two areas, so it would make sense that the organisms that live in those areas might be different also. What might a food web from a tropical marine environment look like? Divide into groups to create your own food web games. 1) The west coast of South Africa - This is an area often associated with phytoplankton blooms.
Energy Flow Through Ecosystems
Summary:The objective of this lesson plan is to give students a basic understanding of how energy flows through an ecosystem by introducing them to the concepts of food chains and energy pyramids. Included in this lesson are two small group activities and a power point presentation. The power point presentation provides the students with fundamental knowledge about one way that organisms in an ecosystem interact and depend on one another. Main Curriculum Tie: Science - BiologyStandard 1 Objective 1Summarize how energy flows through an ecosystem. Materials: LCD projector and classroom computer 1 computer for every 2 students Graph paper Microsoft PowerPoint Internet Access on each computer Attachments Ecological_Food_Chains.ppt Teacher PowerPoint Presentation Student Prior Knowledge: Students will be expected to have a basic understanding of ecosystems and organism interactions. Students will also be expected to have basic knowledge of the Internet and how to carry out Internet searches. Rubric:
