Friday+20th+March+lesson

You will find all the necessary info about preparing for this lesson and how to utilise the class time. Remember that I will expect your presentations to be ready for Period zero on Monday 23rd March. I will keep adding info to this page over the next day but by thursday it will be final (as I will be on camp by then). I will hopefully have the laptop trolley booked for you but you can always ask for permission to work in the pod/library or computer room. The tripod should also be in the lab, in case you want to do a slomation.

Link to biol 3 homeostasis presentations First things first. I need you all to choose one of the following six topics (all relating to humans). Insert your name in the appropriate spot. First in best dressed! There should be 5 groups of 3 and 1 group of 2. I really would like all six topics to be covered.


 * = **Topic ** ||= **glucose regulation** ||= **temperature regulation** ||= **fluid balance** ||= **blood calcium levels (calcitonin)** ||= **blood pressure regulation** ||= **calcium homeostasis (vitamin D) ** ||
 * = **1 ** ||= Mikayla ||= Dani ||= Liv ||= Joshi ||= Lisa ||= Gina ||
 * = **2 ** ||= Mikayla ||= Lia ||= Sarah ||= Ryan ||= Bec N ||= Simone ||
 * = **3 ** ||=  ||= Lauren ||= Yossi ||= Davina ||= Adam K ||= Elena ||
 * = **type of presentation ** || Physically active game; (be afraid, be very afraid!) ||  || Annotated Poster (because we have Yossi in the group to help with the beautifying process) ||   || Powerpoint presentation || Powerpoint Presentation ||

Don't be confused by the two calcium topics. They are different, although there will be some overlap. If you are doing the "vitamin D" one, [|click here] for an episode of catalyst that aired only last week (watch the video) that will provide you with background info.

As a group you will need to decide on how you will tackle your homeostatic system and what sort of presentation you will produce. **When you have done this write this in the table at the bottom of your topic's column.** Here is a list of ideas but you can come up with your own. The MAIN thing is that what ever you do will help you learn your example better and that what you prepare will be helpful to others in the class in terms of understanding that homeostatic system through learning/revision activities.


 * 1) large annotated poster
 * 2) role play the system (that you hopefully video)
 * 3) interview with a biologist (that you video)
 * 4) interactive powerpoint presentation
 * 5) written worksheets/activities that are designed to help learn about your system and/or revise it
 * 6) a slomation of your system (ideally bring you own digital camera to class but I will leave two cameras on my desk for you to use, must be returned to my desk)
 * 7) anything else you feel like you want to do

Whatever the specific details may be about your system it is important that you focus on linking these with the general ideas involved with stimulus-response/negative feedback and nervous and endocrine systems. In other words clearly show what the receptors are, the method of communication, and the response produced in the target cell as a result of the signalling moelcule involved, etc.

If you have any questions, post them below but you must do so by Wednesday evening at the latest (after that I won't be able to necessarily answer them).
