This .zip file contains materials for a middle school science lesson on mutualism, commensalism, and parasitism, as part of a unit on the Interactions of Life (Ecology). The unit was designed for 6th graders in NYC.
1 full lesson plan
1 SMARTboard .notebook lesson presentation (7 slides) including a group activity and video links.
1 homework assignment
Presentations include links to related YouTube videos to increase student engagement (I can help you use YouTube videos in your class, even if your network blocks such sites, just ask).
'Ask a Question' if you need a PowerPoint file instead of what is provided, and I can probably re-upload everything with an adjusted file.
