Biodiversity, examples of extinctions, causes of extinctions.

A worksheet with exam questions to cover the ideas of how to calculate energy change. Includes: The term BENDOMEX (Breaking bonds is ENDOthermic, Making bonds is EXothermic) for remembering where energy is needed/released in reactions How to determine whether a reaction is endo/exothermic based on the total energy change Steps to calculate the energy change in a reaction The worksheet is made to complement the video at https://www.youtube.com/watch?v=skj2GQ8xfQk

A PPT resource used in a lesson about anaerobic respiration - the formation and fate of lactate/lactic acid. Also comments on other anaerobic pathways eg. use of creatine phosphate. Used for Edexcel Biology or SNAB, but may be useful in OCR. The questions referred to at the end are from the SNAB text book.

This document contains the specification of the Edexcel Biology or SNAB (Salters Nuffield Advanced Biology) A2 course. What I have then done is look through the exam papers up to June 2013 and linked in the questions from these papers to the specification points where possible. It has been very useful in providing to students to help them with their revision for specific areas, but also in planning by accessing and using the questions as plenaries/starters in lessons. It includes the specification points from Topic 5, 6, 7 and 8 for the exams 6BI04 and 6BI05. Also includes reference to the pre-release material questions from the Unit 5 paper. Any feedback gratefully received.

A worksheet and complementary video covering: What a chemical cell/battery is The difference between a rechargeable/non-rechargeable cell/battery How a hydrogen fuel cell generates a potential difference Half equations Evaluation of the pros/cons of the various cells

A worksheet following the AQA Spec closely.

A worksheet for covalent bonding with some bond drawing practice and a space to work on different types of covalent structures (small and giant, including allotropes of carbon, designed around the specification for AQA GCSE Chemistry/Combined Science in the Bonding topic. This complements a revision video and could be completed alongside or after watching the video as part of home-learning or revision work.

A revision sheet summarising the Circulatory system part of the organisation topic for AQA’s GCSE Biology. It is shaped by the specification and matches the revision video on the topic at https://youtu.be/JpmxmDCHHX4 A perfect home-work or revision task. It contains: What is found within blood Structure of blood vessels, including arteries veins and capillaries The heart structure Pacemaking cells Heart disease, heart failure, faulty hea rt valve
