Coral Reef Ecosystems: The Abiotic Setting

Good, but less of the stuff I like in Sci Objects
First, I do want to state that I think using coral reefs to integrate and discuss many earth science and physical science concepts as abiotic factors is a good way of presenting this information. I think these are important concepts for a teacher of life sciences (at all school levels) to know. This object includes short overviews of sunlight, ocean temperature, pH, salinity, dissolved oxygen levels, turbidity, pressure, as well as the very basics of waves, tides, and currents. However, for such a variety of topics, there appeared to be fewer questions asked along the way as review and fewer interactives, which are the components that usually make me feel I’m not just reading a textbook online. This is the first science object that gave me more of that feeling. The only interactive is at the end and is basically a visual review question with minimal manipulatives where you have to adjust some of the abiotic factors to create optimal coral reef growth. Again, the info is varied an
