This module has 4 Labs — 3 are microscope labs and one is the Earthworm Dissection! (YAY)
For the first class of this module, I had the students work on the first 2 labs — since we only have 4 microscopes and 10 students, the students waiting for microscopes needed something to do. So, I searched my favorite blogs, googled videos and found some videos for them to watch. I setup 3 laptops and setup the links to 2 videos per laptop. Kept the students moving around the room watching videos and doing the labs.
The first video is of Budding in Hydra (30 seconds) : https://youtu.be/489CSop00sY
The second video is of a Planarian (54 seconds) : https://youtu.be/w0QzSYQGsnA
The third video is of Planarian regenerations- it is about 1/2 way down the page on the right. It is long but good and gross: http://www.exploratorium.edu/imaging-station/research/planaria/story_planaria1.php
The fourth video is of a Cnidarian (30 seconds): youtu.be/Szt42nG-hGg
The fifth video is very cool — 6:04 but interesting: https://youtu.be/7WJCnC5ebf4
The last video is just for fun — https://youtu.be/2KjNH2_QDVs
The second day of class we completed all of the microscope labs and made a paper model of an earthworm. I purchased the model from teachers-pay-teachers and changed it a bit because I thought the highschool students could be a bit more challenged. I had hoped that the paper model would help them to locate the worm parts during the dissection because it really helped me.
