  1. Energy Transfer in EcosystemsLily Dancy-Jones, UNC Asheville • Objective: To explain the transfer of energy in ecosystems and the concepts of food chains, food webs, and trophic levels through a short film. • Prior experience: None.

  2. NCSCOS Objectives Addressed: HighschoolBiology 5.02 • Analyze the flow of energy and the cycling of matter in the ecosystem.Relationship of the carbon cycle to photosynthesis and respiration. • Trophic levels - direction and efficiency of energy transfer. • Analyze food chains, food webs, and energy pyramids for direction and efficiency of energy transfer. Middle School - 8th Grade 3.04 • Describe how terrestrial and aquatic food webs are interconnected.    - • Food webs share similar properties. • Food webs are highly connected and easily disturbed • Food webs interact with one another • The level of toxins in an organism can be increased up the levels of a food web causing biomagnification.

  3. Methods • Windows Movie Maker, Digital Camera, Paint, Microsoft Office ClipArt, Powerpoint Converter • Stop animation, Paint animation, and PowerPoint animation conversion, with voice-over narration • Vocabulary words are emphasized by appearing on screen • Evaluation questions at the end reinforce learning. • Basic concepts and vocabulary research in a variety of Middle and High School textbooks to correspond to NCSCOS • Challenges: slide transition timing from PowerPoint to windows movie file

  4. The Film
