New A2 Revision Quiz

Here is the latest revision quiz for A2 Biology. It covers Unit 2 Module 1 – Cellular Control and Variation. It does not have any detailed genetic problems or maths questions as it is purely meant to be for factual recall of the key words and definitions.

Teaching and Learning – Animations

Recently in my department we have been using modelling clay to help animate complex biological processes that students find hard to visualise and learn. It’s very simple to do, all you need is some modelling clay, a smartphone or digital camera, some pens and paper and some basic video editing software like iMovie or Windows Movie Maker. To make the animations as smooth as possible the students should take as many still frames as they can. These are then put into the software and text, music and transitions are all added. It can be done in the class in small groups or for a homework task. Below are two examples of processes that this works particularly well for meiosis and protein synthesis.

Protein Synthesis:

Meiosis:

Other biology topics that this technique would be useful for include: movement of substances across membranes, the nephron, genetic engineering of human insulin, action potentials, respiration, photosynthesis, enzymes and many more.
