A resource aimed at Advanced Level Biology students, this practical schedule provides a fully detailed method by which students can investigate the effect of pH on the rate at which hydrogen peroxide is broken down by catalase. The experiment itself is straightforward to set up and the data gathered from the investigation can be analysed to produce the classic pH versus rate of reaction graph. The schedule includes several exam style questions based on student's understanding of the practical exercise as well as a mark scheme with answers. Key words: catalase, rate, enzyme, pH, buffer, hydrogen peroxide

A starter worksheet aimed at 14-16 year old biology students, this resource provides a recap of binary fission in bacterial cells. The worksheet covers several areas including the conditions necessary for optimal growth of bacteria, calculation of how many bacteria will be produced after a given time period, aseptic technique and a final challenge question requiring students to calculate magnification of a bacterial cell diagram. An ideal resource to recap several different concepts and skills in the topic of microbiology. Key words: microbiology, bacteria, agar, aseptic, colonies, binary fission

A starter activity aimed at GCSE biology students, this resource consists of four questions that recap the idea of barriers and phagocytosis as a means of defence against pathogens. The activity has both closed and open questions, with the final question requiring students to describe and explain an illustration of phagocytosis in their own words. Key words: phagocytosis, barriers, pathogens, defence, immune system

A starter worksheet aimed at GCSE Biology students, this resource provides five questions that recap basic definitions and the concept of magnification. The final questions require students to make measurements of the bacterial cell diagram and calculate magnification of the image (converting millimetres to micrometeres in the process). A useful resource to use in order to reinforce some of the basic ideas on the topic of bacterial/prokaryotic cells. Key words: AQA, biology, bacterial cells, magnification, micrometres, prokaryotic

A resource suitable for post-16 year old students, this worksheet explores the reasons why fertilisers are necessary for healthy plant growth and the advantages/disadvantages of natural and artificial fertilisers. Key words: Natural, artificial, fertiliser

A resource aimed at GCSE biology students, this worksheet provides a brief review of basic key terms (e.g. antibody, antigen, phagocyte, lymphocyte) followed by more open ended and challenging questions that require students to fully explain the principles of active immunity in their own words. Key words: active, immunity, phagocyte, lymphocyte, vaccination, antibody, antigen

A worksheet aimed at A-Level Biology students that asks students to apply their knowledge of ecology to that of conservation. The worksheet focuses on how our knowledge of succession can be used to conserve moorland and native bird species in the UK. Full answers are provided on the second page of the worksheet. Key words: Succession, conservation, moorland, birds, ecology, ecosystem, habitat

A worksheet aimed at A-Level Biology students which begins with a quiz on key word definitions (e.g. habitat, population, community, ecosystem, biotic factor, abiotic factor) and then moves on to the concept of diversity. The worksheet includes an exercise on calculating diversity index for two habitats and subsequent interpretation of results. Keywords: Biodiversity, habitat, population, biotic, abiotic, ecosystem, community, population, diversity index

This is a personal learning checklist (PLC) tailored for the first year of the new AQA Biology Advanced Level specification. This is an excel spreadsheet with five worksheets in total, each one covering specification references: 3.1 Biological molecules 3.2 Cells 3.3 Organisms exchange materials 3.4 Genetic information 6.1-6.5 Mathematical requirements Each worksheet contains the full list of statements/learning outcomes taken directly from the specification, along with a grid for students to RAG rate their confidence as well as space to write notes and set targets.
