Revision flash cards and Q/A matching activity - all in one! Two sets of revision flash cards for the Pearson Edexcel Biology GCSE (9 - 1) course. They include 2 or 3 questions relating to every chapter in the Pearson GCSE Biology textbook. Set 1 covers Paper 1 (Units 1 - 5). Set 2 covers Paper 2 (Units 1 & 6 - 9). Higher tier questions are highlighted with grey backgrounds. There are 2 versions of each set; the back-to-back set is arranged for double-sided printing to give ready-made cards with question on one side and answer on the other, so you can print directly onto A4 sheets of card, or laminate a paper copy. ** (I did find that the alignment was a bit off when I used my automatic ‘print on both sides’ setting, but manually feeding the paper got the alignment bang on.)** The other set of each has question and answer paired, so you can cut them out, fold in half and glue or laminate to make the cards. Also, these could be used for a matching exercise if you separate the questions from the answers.

PowerPoint presentation for** A-level Biology** (prepared for** OCR Biology A** specification [from 2015] but probably applicable to other boards as well), detailing the stages of aerobic respiration, including an animated explanation of oxidative phosphorylation, and anaerobic respiration with a comparison between animal and yeast cells. Presentation includes: glycolysis, Link reaction, Krebs cycle with info about why there are 2 cycles per glucose molecule, an animated sequence though the stages of oxidative phosphorylation which demonstrates the role of reduced NAD, the transfer of electrons along the ETC, pumping of H ions, chemiosmosis and phosphorylation of ADP, the role of oxygen and formation of water, and why reduced FAD gives a lower yield of ATP than reduced NAD. Anaerobic respiration starts by revisiting glycolysis and explaining the need for recycling NAD, then compares the processes used by animal cells and yeasts. The animation is stepped so you can go through it at your own pace, adding further explanation at any stage, and rewind using the back arrow key. It was prepared using Office 365, so it is possible that some features may not be supported by earlier versions of PowerPoint.

This presentation is for A-level biology students. It explains the distinction between Homeobox and Hox genes (often done incorrectly in web presentations), what they do, what are homeodomains and clusters. My Y13 class were dreading this topic after pre-reading, but now they understand it.

Aimed at A-level Biology students. This is simply some instructions on how to make a 2D model of a synapse from plasticene and various odds-and-ends, and some photos of what my less-able sixth-formers created. The model can be used to illustrate the mechanism of a cholinergic synapse, and also to study the effects of different types of drug on the functioning of the synapse. While the idea is quite simple, hopefully it will lead to some other ways to use modelling for explaining biological processes. A pound’s worth of inspiration?

I use this to check students' grasp of the sequence of events in DNA replication, based on AQA NT textbook. They work in pairs to see who can get the sequence correct in the shortest time. The colour of the text allows a rapid check of the sequence - when correct, it runs the colours of the visible spectrum from bottom (red) to top (violet). Of course, there&'s always a chance that some students will spot this as well...

Light dependent reaction, light independent reaction. 'Green boxes&' with input and output arrows. Moveable labels (click-and-drag with mouse or on IWB) which are all in the wrong places to begin with. Labels can be moved to edges as alternative start. Useful as introduction before looking at details of reaction pathways, review of whole process, and when explaining limiting factors.
