This 49 slide interactive presentation is artfully designed as a compliment to your unit on Ecosystems! It is specifically tailored for the Tennessee Curriculum by McGraw Hill, but can accompany any lesson on ecosystems, habitats, biotic and abiotic factors. The presentation ends with a quiz or review of the material with answers. The PowerPoint is designed to be a complete stand alone lesson. It begins with the lesson vocabulary, defines ecosystems, presents different types of ecosystems, and then presents the difference between biotic and abiotic factors. There are many pictures throughout. There are many questions to allow the presenter or teacher to stop and engage students in discussion. There is a slide where students must identify if items are abiotic or biotic. Then the various habitats are presented with visuals to show the differences.
Competition among organisms is presented with environmental changes. The predator prey cycle is presented with examples; it ends with a Checkpoint to measure student learning.
