biol+3+question+grid

Question grids are a useful way to summarise an area, as well as deepen your understanding of concepts. Below are some set up for different areas of the course. The top one is for posting questions and the bottom is where you post the answer. When completed I will create a powerpoint file of these for you to be able to use as a quick quiz/revision tool. You don't have to complete one on your own. Ideally as many of you contribute to each one. The real benefit in this activity is in you having to create questions and answers. I suggest that you do one for the homeostasis and signalling molecules section, seeing as you have SAC on this 2nd week fo term 2. Back to biol 3 term break work

By being able to create your own questions (and answers) that cover the course you are taking the important step of strengthening your understanding of the content. This will allow you to deal with anything that is thrown at you, like an ex-president did when a shoe was thrown at them (seeing as you are into famous/infamous world leaders). Now hopefully others will contribute to this, otherwsie they will be risking only having a superficial knowledge. VM
