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

Students choose from a bank of statements. They categorise the statements as advantages or disadvantages. Different students will take different points of view. They then have to write a sentence to justify each choice. A cut and stick exercise designed to provokes discussion. To complete the activity students must engage with the concepts. There are no ‘right’ answers! 3 pages Key words Genetic modification, GM, Ethics, Genetic engineering,

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

Students colour in and label diagrams of motor and sensory neurones (nerve cells), identifying the axon, neuromuscular junctions, fatty sheath and dendrites. There are cloze (gap fill) questions alongside the diagrams. 2 pages, with answer sheet

This is a cloze activity with the words (2D, 24A) linking into a crossword. Covers fitness, heart rate, ATP production, breathing, oxygen uptake and muscle development. 2 pages with an answer sheet. Written to accompany A-level Biology.

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

Pond snails: Worksheet in which students are led through the idea of natural selection - reproduction, inheritance and survival - using pond snails and leeches as an example. 2 pages, accompanied by an answer sheet. Giraffes: Students put a variety of facts about giraffes into categories. The categories relate to Darwin’s observations. Students then write a paragraph to explain how longer giraffes’ necks have been selected. Designed to provoke discussion about inheritance, evolution and natural selection. 2 pages with answer sheet. Peppered moths: Students put pictures and statements in the correct order to tell the story of natural selection in peppered moths before and after the industrial revolution. Supports learning about genetics, inheritance, predation, camouflage and survival. with answer sheet.

A double sided GCSE worksheet with answer sheet. Pros and cons of sexual/asexual reproduction. Recall, Cloze, Free response, short answers. Strawberries, potatoes, mice, amoebae and gardeners.

We use this as a christmas revision quiz before Jan A-level trials. Fun, competitive and a stress buster. Obviously needs reward for 1st completed etc. 0 = WPOPW (Water potential of pure water) 3 = BIAC (OA) 6 = CAIG etc.

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).

My lower ability GCSE students struggled distinguishing between genes ‘being’ the protein and genes ‘coding’ for the protein. The language was a barrier - weird, abstract words. This sheet uses a recipe-cake / gene-protein analogy with a bit of colour coding. The students enjoyed it and understood it. (I pointed out that medical students use colouring in to learn anatomy). Answers included

Worksheet with questions leading the students on to balance the equation for photosynthesis and then looking at what the glucose is used for in the plant. Double sided accompanied by an answer sheet

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 wordsearch, colouring, labeling worksheet to engage foundation tier GCSE students. Answer sheet provided.

Triangle puzzle on ‘DNA, genes and chromosomes’ where students match sentence fragments to construct a large hexagon. It is a revision activity which works across the ability range and is enjoyed by students. Weaker students need hints! It could be used for groups of three, and it works well as a race. An answer sheet is provided. Written to support A-level Biology.

This looks at alpha/beta/gamma radiation. An onscreen cloze/labelling activity written in Excel; it ticks each word as students get them correct. Students like it because it gives immediate feedback. I’ve used it with all ability groups at GCSE. If you want to work out how it’s done, the password to unprotect it is ‘eliziczac’. Save as a template to stop students overwriting the original. Works well on a VLE.

23 Cue cards which have all the equations which students need to learn for AQA 9-1 GCSE Physics (both Combined Science and Separate Science). They’ve only got 23 to learn (I resisted the temptation to add a few extra in to fill all 27 cards). To print: Flip on long edge

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).
