A worksheet aimed at GCSE biology or applied science students, this resource provides a basic introduction to the concept of respiration and the movement of reactants and products into and out of cells. The worksheet also includes a table requiring students to research the uses of energy that is supplied by respiration. Useful as an introduction to the topic or as a recap of what has already been learnt previously. Key words: respiration, energy, carbon dioxide, oxygen, glucose, cells

A resource aimed at high ability GCSE or advanced level biology/applied science/health and social care students, this worksheet provides a useful comprehension task for students to gain an understanding of the nature of x-rays, their use in diagnosis and their relative advantages and disadvantages. Key words: x-rays, contrast media, hazard, radiation

A resource aimed at GCSE or A-Level biology, physical education or applied science students, this worksheet provides a series of instructions to investigate the effect of exercise on blood pressure, heart rate and cardiac output. The worksheet includes a weblink to an online metronome for students to standardise their rate of exercise (e.g. squats)and also provides a graphic to gauge whether blood pressure is optimal or above normal. Key words: blood pressure, sphygmomanometer, exercise, heart rate, cardiac output, recovery

A resource aimed at either GCSE (high ability) or A-Level biology students, this worksheet consists of both an independent research exercise and a series of 'big' open ended questions that require extended answers. The independent research exercise provides key questions prompts to lead students through their research of the structure of the lungs and how ventilation and gas exchange occurs in the lungs. Internet websites are provided in the list of available resources which include animations and video clips. The 'big question' prompts on the second page of the worksheet encourages students to think more deeply about the topic and provide coherent, extensive answers to open questions about the lungs and ventilation. Key words: Lungs, ventilation, alveoli, trachea, bronchi, gas exchange, oxygen, carbon dioxide, intercostal muscles, diaphragm, research, oracy

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

A resource aimed at GCSE biology students, this worksheet provides a quick review quiz on the basics of the specific immune response followed by a more in-depth focus on the difference between primary and secondary responses with reference to the classic graph showing changes to plasma antibody levels over time. This is an ideal resource to use in order to probe student's understanding of this complex topic and ensure they have properly grasped the essential information. Key words: Immune, vaccination, lymphocyte, primary, secondary, antibody, antigen, pathogen

A starter activity aimed at GCSE Biology students, this worksheet provides eight questions that probe student's understanding of what antibiotics are and how their effects can be seen in the laboratory. The worksheet includes reference to an image of an agar plate with zones of inhibition around different types of antibiotics - ideal as a starter/preparation for a lesson involving this practical activity. Key words: antibiotics, bacteria, Alexander Fleming, zone of inhibition, efficacy, incubation

A mark scheme posted in response to a request from a customer that purchased the nitrogen cycle worksheet: https://www.tes.com/teaching-resource/nitrogen-cycle-11285758

A worksheet to be used as an introduction to enzymes. The weblinks at the bottom of the worksheet link this topic to the some of the neurotoxins and haemolytic toxins found in snake venom - an engaging context to spark the interest of learners.
