Assignment outline

I'm going to try to reconstruct the notebook presentation, but it's not ready year.
Here is a link to the google doc with the schedule.

Here is the current version of the project I'm working on. There may be some small changes.

AP BIOLOGY/BISHOPS/2018

A Brief Survey of Animal Biodiversity

This project allows students an opportunity to explore our biodiverse world by examining evolutionary relationships among different groups of animals, both invertebrate and vertebrate, by tracing the development of an organ system or physiological process in several representative phyla. I will do one of the examples, probably osmoregulation. Not only will students describe the general anatomy and physiology (i.e., structure and function) of each system and its component organs, they need to address the following:


        Presentation will be in discussion with the class. Most if not all of the work should be done in class. The goal for us is to learn together (ok, well, I know most of it…but even I will learn some new stuff).


        CIRCULATORY SYSTEM: cnidaria, arthropods, fish, amphibians, mammals

        GAS EXCHANGE/RESPIRATION: cnidaria, annelids, arthropods, fish, mammals

        DIGESTIVE SYSTEM: porifera, platyhelminthes, annelids, cow (or other ruminant), wolf (or other
        carnivore)

        OSMOREGULATION: cnidaria, arthropods, fish, birds, mammals

        REPRODUCTIVE SYSTEM: cnidaria, nematodes (C. elegans ), amphibians, reptiles, mammals (monotremes, marsupials, placentals)












        Questions to guide your research and create your presentations:

        Circulatory system: How do the selected organisms move food/gases/etc. around their bodies? Do they have organs/systems to deal with this and if not, how do they solve the problem? You will want to discuss difference between open/closed systems and differing heart chambers.

        Gas exchange/respiration: How do the selected organisms obtain oxygen and remove carbon dioxide waste from their bodies? Do they have organs/systems to deal with this and if not, how do they solve the problem? You will want to discuss parapodia, cutaneus exchange, tracheal systems, gills and lungs.

        Digestive system: How do the selected organisms obtain food? You will want to discuss intracellular vs. extra cellular digestion, complete vs. incomplete digestive tract (gastrovascular cavity), digestive organs, accessory organs, chemical vs. mechanical digestion.

        Osmoregulation: How do the selected organisms regulate their internal solute concentrations, focusing specifically on their nitrogenous wastes via excretion? Do they have organs/systems to deal with this and if not, how do they solve the problem? You will want to discuss osmoregulator vs. osmoconformer, malpighian tubules, advantages/disadvantages of creating different forms of nitrogenous waste (ammonia/urea/uric acid) , basic structure/function of nephron.

        Reproduction: How do the selected organisms make more of themselves? Do they have organs/systems to deal with this and if not, how do they solve the problem? You will want to discuss the advantages/disadvantages of asexual vs. sexual reproduction, the role of male/female/hermaphrodite, internal vs. external reproduction, and the evolutionary progression of reproduction from aquatic eggs to terrestrial amniotic eggs to placental births.
