I did a lesson recently on the basics of Parasitology. I had a hard time getting the students involved in it. I wasn't very well prepared either. What would be a good interest approach to really get them interested?
A great interest approach that worked for me was actually having the parasites or at least a few of them (in bottles). You can call up Cache Humane Society or a local veterinarian and they would be more than happy to let you borrow or even have some of their parasites. When I did this the students were really grossed out but it helped them identify what they really look like instead of just showing them a picture. Hope this helps!
I agree with Brittany on this one. Actually bringing in the parasites and showing the class what they look like and why they are considered parasites would be a good interest approach. Also I found the fun activity to let your students "create" their own parasite. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CCMQFjAB&url=http%3A%2F%2Fci.coastal.edu%2Fresearch%2Fgk-12%2F_media%2F08%2Fplans%2Fhigh_school%2Fparasite-activity.doc&ei=5IMtVdbvH9e3oQTqmoCoBg&usg=AFQjCNF0Dc3SS18shIztfTMGEkYjFdo0gQ&bvm=bv.90790515,d.cGU
One thing we did was let students bring in samples from their pets to preform fecals. Granted I had to remind them that we aren't experts so don't freak out if you see something. It helps too to ask if their pets have ever had a parasite.
