Bring the concepts of energy flow and tropic levels to life with this engaging PowerPoint and research activity. Student minds are blown by the idea of exponential growth curves and how they impact human populations. This lesson guides students through these concepts with contemporary applications and color images.
Your purchase includes a 30 slide, color PowerPoint presentation, which includes instructions for the Food Web research and poster activity, as well as a student note handout. There are links to suggested videos to help bring the PowerPoint presentation to life. The content takes about 90 minutes to cover, either in one block-schedule lesson or two regular length lessons.
My favorite part of this lesson is watching student's reactions to the video about the reintroduction of the wolf to Yellowstone National Park and how that has impacted the delicate balance of that ecosystem. Students then apply what they have learned to their own food web research and poster activity.
