I up to date my cat dissection information this 12 months to incorporate all of the physique programs. In earlier years, I might do cat muscle tissue within the first semester after which the cats would go into storage till the spring. This 12 months, the scholars dissected that cat on the finish of the spring semester.
I additionally added a part the place college students would tag the cats as they went and add images to Google classroom. I really feel that this actually helps them stay on activity. This additionally helps have interaction college students who are usually not as more likely to contact the specimen. They’ll do the labeling and importing. This 12 months, I gave them pupil whiteboards as a solution to label the cat. You too can purchase pins with numbers or simply give college students coloured pins and so they can shade code their key.
Scholar Dissection Information
The full dissection information begins with the muscular system, then strikes to the circulatory system. Lastly, college students study the primary organs of the physique cavity, which is generally the digestive system. The information walks college students via the steps of the dissections and has them carry out duties alongside the best way, like measuring the size of the small gut.
One pupil within the group can full the packet whereas others do the dissection. Right here is one other alternative to have interaction somebody who may be a bit squeamish about touching the cat. Different duties embody sketching the organs or writing down observations.
A remaining picture reveals organs for college students to label, which incorporates the abdomen, pancreas, small gut, spleen, and colon.
Evaluation and Examine
Periodically, all through the week, I’ll pause to share images on the overhead to elucidate what college students are seeing. There are some buildings which can be troublesome for college students, like the situation of the pancreas and the arteries that department from the aorta. I hold images saved in a Google Album.
I even have a apply set the place buildings are pinned and college students can advance to see the solutions. This set may be used for an evaluation, or you’ll be able to obtain a safer doc from TpT. The take a look at is a set of images displayed on PowerPoint. College students write the solutions on their very own paper, which will be differentiated for honors (no phrase financial institution) and common observe college students (with phrase financial institution.) You’ll be able to obtain the clean reply sheet free of charge. (Reminder: when accessing shared recordsdata on Google drive, make sure that to repeat it to your individual drive if you wish to make edits.)
