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

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 worksheet aimed at high ability GCSE or advanced level biology or applied science students, this resource provides a research task for students to complete independently on the topic of thermoregulation. The worksheet has clear criteria for the research task and provides several individual prompts that lead students through the task. Weblinks are provided at the end of the worksheet. Key words: thermoregulation, temperature, research, vasoconsstriction, vasodilation, shivering, piloerection, respiration, core temperature

A worksheet aimed at high ability GCSE or Level 3 Physical Education or Applied Science students, this resource provides eighteen 'what am I' questions that relate to the topic of respiration. The questions probe knowledge that is slightly above GCSE but not quite at the level of advanced biology. A useful exercise to set as a plenary of key vocabulary, as a starter task recapping a previous lesson or as a homework challenge.

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 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 advanced level biology, applied science or physical education students, this worksheet comprises of a series of questions that discuss the nature of an ECG and its interpretation. The worksheet also includes questions on abnormal ECG traces and diagnosis of conditions such as tachycardia and bradycardia. A useful resource to use as a lesson starter or plenary once this topic has already been taught.

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.

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.
