Symbiosis Lesson, Parasitism, Middle Level Science Slideshow from SlideSpark Science

This lessons briefly describes the types of symbiosis and then divers into parasitism. Parasites are covered with a definition and the importance of studying them as well as their often complicated life cycle addressed. Both endo and ectoparasites are described and student have to answer a few questions with visuals as to which picture is an endo and which is an ectoparasite. A series of images follow after a warning to the audience. Various worms are shown and this part of the slideshow shows the disgusting side of the parasite world. Please preview before showing students as some images could be unsettling! The cow bird and brood parasitism is also described and students must pick the cowbird eggs from a a group of eggs in a nest. Directions are then provided for students to create their own PowerPoint presentation of a parasite. A link to the CDC provides a giant list and students spend some time viewing parasites before creating their own parasites. I usually have the students then present their parasite slideshow as a large group and students wander completing the research portion of the supplied homework. A sample presentation is provided about scabies to provide a format for the students.
