Interactive powerpoint presentation: brain structure and function

This powerpoint presentation is designed for A2 Biology and matches the Edexcel course as it includes sections on brain imaging technology. However it is fairly standard so would suit all exam boards. A key feature of this presentation is that it has interactive drag and drop exercises so gets the students up to the white board. It also has lots of links to relevant short videos and websites. It also includes a mini quiz to help revise the structure and functions of parts of the brain, students can just write their one word answers on scrap paper. I have also included worksheets to fill in during the presentation and some notes pages in case students are absent etc. Note: if you want to incorporate the drag and drop exercises into your own presentation you will have to modify this presentation and add your own stuff to it, the slides will not copy and paste into other presentations without the drag and drop macro.

A2 Biology: transcription factors PowerPoint presentation

This is a short presentation about transcritpion factors and matches the Edexcel Concept approach textbook (although this textbook is not needed to use the presentation). Obviously it is possible to insert activity and question slides wherever appropriate (eg. last slide for Edexcel activity sheets). The presentation has animations and works best in conjunction with the Hormones and performance enhancing drugs presentation. Personally I would introduce transcription factors first then cover hormones, though the textbooks do it the other way round. If you choose to do it my way then the last activity slide needs to be deleted or transferred to the hormones presentation.

AS Level: PowerPoint presentation on how the CFTR protein works

PowerPoint presentation: What causes cystic fibrosis

This follows the diagrams within the AS Level textbook describing how the viscosity of mucus is regulated by the CFTR protein and how a non-functional CFTR protein results in cystic fibrosis. The slides are fully animated and follows the various movements across the membrane. I think it is also important to add that the CFTR protein is a gated channel protein and requires ATP for it to change its shape. However, this is still facilated diffusion and NOT active transport as the chloride ions still diffuse down their concentration gradient. I saw a past exam question that introduced the use of ATP with the CFTR protein and it confused nearly all of the students into thinking it was active transport. It is probably very useful to read the textbook so that the explanations for slides 2, 3 and 4 are easy to give but I think, even if you don´t have the textbook the slides are easy to understand (plus I plan to do a quick video soon, which will help). The remaining 3 slides quickly explain how cystic fibrosis affects the lungs, digestive and reproductive systems.

The textbook used:

A2 Edexcel Biology: Hormones and performance enhancing drugs

Powerpoint presentation:

A2 Biology Topic 7 Hormones

Worksheet:

Banned substances and practices in sports

This is a Powerpoint that is based on the final chapter for Topic 7 Run for your life (from the concept approach textbook). I do think though it is adaptable for either the context or concept approach. It includes 2 animated slides to show the action of steroid and peptide hormones. I also added a slide to explain what steroids are and give examples of steroid hormones plus other steroids found in the body. I have been a little naughty and not added any quiz or activity slides throughout the presentation, but obviously teachers can add those. There is an essay at the end base don the ethics section in the text book and is a copy of the essay question included, so I think the teachers guide will have the answer scheme.

Presentation: Classification-plants, fungi, bacteria and viruses

This presentation reviews aspects of the Cambridge IGCSE syllabus that cover monocotyledonous and dicotyledonous plants, bacteria, viruses and fungi.
