Accompanied by an interactive powerpoint with clear diagrams which can be used on a smartboard to show students what they should have coloured in (11 slides) Key words Oxidative phosphorylation, Electron transfer chain, Cristae, Mitochondrion, Mitochondria

A fully illustrated, hyperlinked, animated powerpoint presentation (21 slides) introduces the Hardy-Weinberg principle. Includes assumptions, derivation and three examples: Banded snail, Rhesus and Kuru (a prion disease caused by cannibalism in New Guinea). The word document includes 3 double-sided worksheets and full answer sheets. They were written to accompany the powerpoint. Aimed at A-level students.

Interactive presentation which takes students through using the chi-squared test to check the significance of results from a dihybrid genetic cross. Uses examples from Mendel’s pea plant experiments. Can be used on a smartboard to reveal each stage after quizzing the students. 6 slides. Written for A-level. Key words Dihybrid cross, Inheritance, Sweet peas, Mendel, Chi squared, Genetics

Two sheets of straightforward revision questions. Written to provide simple recall test of what students have learned and need to learn (to reassure them as much as anything).

Animated, interactive powerpoint which guides students through the countercurrent system of fish gills and the tracheal system of insects (28 slides). It is hyperlinked so that you can choose which bits to show. The accompanying document comprises three worksheets and answer sheets. They use a variety of cloze / colouring / short answer questions

Five sheets of straightforward revision questions. Written to provide simple recall test of what students have learned and need to learn (to reassure them as much as anything). Taken pretty much directly from the AQA A-level Biology specification. Answer sheets are included. Would work well as a starter, plenary or on a VLE. Doesn’t say ‘test’ on it so that it can be used for consolidation within the lesson. (The second carbohydrate sheet deliberately repeats some of the first sheet because I found that students needed a second go once they were more aware of what was required following the first one!) Key words carbohydrate ~ glycosidic bond ~ condensation ~ hydrolysis ~ glycerol ~ triglyceride ~ lipid ~ fatty acid ~ ester bond ~ sugar ~ phospholipid ~ monosaccharide ~ disaccharide ~ Benedict’s test ~ saturated ~ unsaturated ~ hydrophilic ~ hydrophobic

Sorting activity designed to familiarise students with biological molecules. Students sort molecules into groups of similar structures and try to identify them as fatty acids, glycerol, sugars, amino acids etc. 1 page with answers. I have used it both to introduce biological molecules and to round things off once the students have met them all.

Students attach labels in the right place on a template. The template is lifted up behind a diagram of the action potential. One at a time, each stage of the action potential is revealed in windows. It is worth showing students a completed slider (from a distance!) so that they can see what they are aiming for. Craft knives or scalpels best for cutting out the boxes. Answer sheet included. Written to support A-level. (Big font labels for labelling the diagram; Small font labels are for the voltage gated channel table) Key words Action potential, Neurones, Nerves

A powerpoint for students to edit and complete. Written as a cover lesson to give fairly disaffected / less able students something a bit more interesting to do than 100 minutes of worksheets. The answer sheet gives suggested extensions for those who finish first / want them. It would work well as a VLE homework activity or as revision. Key words, Digestion, Digestive system, Enzymes, Absorption, Excretion

Double sided GCSE revision worksheet - Circulatory system and Transpiration. Anagrams, Join the word to the definitions, True/False, Cloze - a bit of everything, really. Answer sheet provided. Key words Blood, Heart, Xylem, Transpiration, Platelets, Stomata

Students edit the Word document to show the stages of glycolysis (oxidation, phosphorylation etc). The molecules are all drawn for them (hexose, glucose, phosphates); they need to copy and put them in the right places. 1 page, accompanied by an answer sheet. Written for A-level students. Works well on VLE as homework but I tend to use it where I can watch what their misconceptions are and deal with them. (‘ctrl d’ doubles an object, which is useful).

Fully hyperlinked 30-slide powerpoint and two worksheets. Used with A-level students. Written in frustration at the lack of material available to stretch bright students on this subject; classification and phylogeny. The concepts can be difficult for students from 14-16 yrs but they do engage with them. Designed to generate discussion about some of the more contentious issues involved in classification. Two double-sided worksheets with answer sheets.

A 20 mark test on circulation for more able students. Straightforward and easy to mark. First image is from from ‘Biodidac’ - so it must remain a free resource. Answer sheet provided.
