A summary diagram that links together the main reactions involved in photosynthesis so students can see how the reactants and products of each stage link up. Intended use: a summary diagram / poster / aid to teachers / A3 sheet handout Course: eg. 2016-2018 CIE A2 Biology syllabus Topic 13. Ability level: suit more able students and visual/spacial learners. Includes: Main structures: Chloroplast, Stroma, Thylakoid, Reaction centres, Photosystems (I) and (II), Thylakoid lumen. Main stages: Light dependent stage and light independent stage Main processes: Photolysis, cyclic and non-cyclic photophosphorylation, electron transport chains, chemiosmosis, Calvin cycle, carboxylation, reduction, regeneration. Main chemicals: CO2, H2O, Chlorophyll a 680 and 700, ATP, ADP, reduced NADP, ATP synthase, Rubisco, RuBP, GP, TP. The 1st page is a screen snapshot as the complete diagram may look scrambled in some browsers when enlarged.

Interest only, although it contains numerous concepts covered by a variety of biology courses. Biology is the study of life. CRISPR will alter the course of life. No other technology offers so much hope or concerns for life. CRISPR is so new it has yet to reach schools as part of a formal syllabus, but it will very shortly. If you are a biology teacher, student or have an interest in science you will find CRISPR profound, my students did. After reading this short summary one of my A2 biology students read several more articles and a text on CRISPR then applied to a university in the US stating that he wants CRISPR to be his focus. You can literally write your own code, order it on line and have it delivered, in a vector, in 48 hrs, for under $50. One company claims "600,000 completed gene synthesis projects for scientists around the world". Could be a 1 period data projector presentation or stimulus for research.

A 2hr experiment / laboratory investigation. Suit any syllabus that examines gel electrophoresis. What you need: A gel electrophoresis kit. 'DNA Marker' although you could use the result provided. Standard food dyes. This 3 page handout contains an Introduction explaining gel electrophoresis, a method, space to enter their results plus some Qs. This lab is a more simple alternative not requiring the more expensive DNA and more dangerous chemicals while still investigating the same properties of the process.
