This is a 12 page smartboard presentation that goes through 9 habitats/ecosystems: freshwater, ocean, deciduous forest, coniferous forest, tundra, desert, savanna, rainforest, and temperate grasslands. Each habitat includes pictures, a brief description, and a link to a youtube video that gives more information. At the end of the presentation are three interactive review activities/games for the smartboard. (For the final game, students pick a habitat and a category: either giving a description or an animal. If they give a correct answer, the cell in the chart is revealed and they either win points for their team or lose them all)
I used this for my second grade class as a fun end of the year project, but the material would most likely better fit an older classroom.
