This web resource is a TEDx talk about zinc and zinc's role in the early stages of the maturation of the egg. This would be a great introduction video for a gen chem, inorganic, or bioinorganic chemistry course. It introduces the idea that Zinc is stored in specific locations on the egg and then released all at the same time.
It is not very long and should give the students lots of questions. Following this video, the students can do the related literature discussion and in-class activities on the O'Halloran Paper to obtain more bredth and in-depth work (see links in "related activities"). Directing students to O'Halloran's website is also an option in conjuction with haveing them see the video.
It is a youtube video and should work on most electronic platforms.
Students will be able to appreciate the role of Zinc as an important signalling chemical in biological systems
Students will identify when zinc fluxes occur early on in development
Students will recognize the important role of inorganic chemistry in multidisciplinary cutting edge research.
Two group LOs were developed at the 2014 IONIC VIPER workshop relating to Tom O'Hallorans work, and this could be used to introduce O'Halloran and his work prior to giving the review chapter to read.
This video would also be excellent for gen chem or non-majors students who are interested in health to talk about inorganic chemisry in biology. You could also have a discussion on zinc sensors. Why do sensors need to be used? This gets into a discussion of metals in the cell, techniques, the specific properties of metals and complexes that can be measured, etc.
Given its short time, students could also watch the video in class and then have the group discussion right there.
Students can also be linked to O'halloran's website to learn more who he is about what he does.
Has not been evaluated yet, but I plan to have it included in the discussion of O'Halloran's review when I have it in my class.
