A worksheet (three different versions are included) that is aimed at Advanced Biology students and which discusses how heart rate is controlled by both the brain and hormones. Each worksheet has a slightly different emphasis and can be adapted to the needs of your class. Topics covered include: 1. How the heart is innervated by the brain 2. The nature of sympathetic and parasympathetic control 3. The involvement of hormones in controlling heart rate 4. The action of neurotransmitters at synapses 5. The action of drugs that can affect the cardiac cycle 6. How chemoreceptors and baroreceptors are involved in maintaining a constant blood pressure

This worksheet is aimed at high ability GCSE or advanced level chemistry/applied science students. The resource consists of two pages, the first of which is designed to be used as a brief starter activity to recap the basic principles of a titration. The second page provides some exemplar calculation exercises for students to practice until they grasp the theory behind this experiment - how the results of a titration can be used to estimate the amount of aspirin present in a tablet and comparison with manufacturer estimates. The resource is useful at the start of this investigation in order to set the scene for the investigation. Key words: titration, phenolpthalein, sodium hydroxide, acetylsalicylic acid, aspirin

A resource aimed at applied science/health and social care or medical physics students (either level 2 or 3) that provides a vocational discussion on how radiopharmaceuticals are used in the treatment and diagnosis of illnesses. The worksheet contains twelve questions that students are required to answer while the video plays (link to youtube video is provided on the worksheet). This is best used as a starter activity for this topic and as a prompt for further discussion. Asking students to answer questions while they watch the video helps to ensure that they are actively engaged and that they have a record of the information in their notes afterwards. Key words: radiopharmaceuticals, isotopes, cancer, radiotherapy, imaging, gamma, beta, alpha, radiation

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 advanced biology, applied science or physical education students, this worksheet provides several questions that lead students through the topic of blood doping. Lance Armstrong is used as a contextual example of an athlete that has been disgraced following the revelation that he was involved in blood doping; the worksheet provides questions on the effect of EPO, the impact on blood cell counts and how haematocrit tests could be used to provide evidence. The worksheet also has follow up questions on the use of steroids and diuretics in sports. Key words: Sports, Blood, doping, haematocrit, EPO, steroids, diuretics, lance armstrong, blood volume, steroids

A worksheet aimed at advanced level biology or applied science students, this resource provides several question prompts that require students to research norm blood count values and the nature of various diseases and disorders of the blood: leukaemia, sleeping sickness, anaemia and malaria. The worksheet includes weblinks and references for students to use as part of their research. Key words: blood, count, malaria, leukaemia, sleeping sickness, trypanosomes, plasmodium, anaemia, red blood cells, white blood cells, erythrocytes, leukocyctes

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 resource aimed at either level 2 or level 3 science students, this single page worksheet provides a series of questions that students should answer as they watch a video demonstration of alpha, beta and gamma radiation. This resource is very useful for occasions where suitable practical demonstration equipment and radioactive sources are not available. The worksheet covers the nature and behaviour of alpha, beta and gamma radiation and is suitable for use as a lesson starter.

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 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.
