This fully-resourced REVISION LESSON has been designed to provide the students with numerous opportunities to assess their understanding of the content of topic 12 (Energy and respiration) of the CIE International A-level Biology specification. The importance of this metabolic reaction is obvious and this is reflected in the volume of questions in the terminal exams which require an in depth knowledge of the stages of both aerobic and anaerobic respiration. The lesson contains a wide range of activities that cover the following points of the specification: Glycolysis as a stage of aerobic and anaerobic respiration The use and production of ATP through respiration Anaerobic respiration in mammalian muscle tissue The stages of aerobic respiration that occur in the mitochondrial matrix Oxidative phosphorylation The use of respirometers Calculating the respiratory quotient value for different substrates Revision lessons which cover the other topics of the specification are also uploaded and tie in well with this lesson.

This engaging REVISION LESSON has been designed to cover the content of topic 13 (Photosynthesis) of the CIE International A-level Biology specification. Filled with a wide range of activities, that include exam questions with explanations, quick tasks and quiz competitions, the students will be motivated whilst they assess their ability to apply their knowledge. Due to the obvious importance of this reaction, assessment questions are extremely common and so a deep understanding of this topic is key to success and the lesson has been designed to cover the important ideas. The following sub-topics have received particular attention in this lesson: Photophosphorylation An outline of cyclic and non-cyclic photophosphorylation Photolysis of water The light dependent reaction The structure of the chloroplast and the site of the different reactions The Calvin cycle The limiting factors of photosynthesis Investigating the effect of light intensity using DCPIP as a redox indicator and a Hill suspension The effect of temperature on the rate There is a focus on terminology throughout the lesson so that students are comfortable with the terms that will be encountered in exam questions. Revision lessons on the other topics of the specification are uploaded so please take a moment to look at those too

This revision lesson contains a wide range of activities that will challenge the students on their knowledge and understanding of the content detailed in topic 3 (Conservation of energy) of the Pearson Edexcel GCSE Physics specification. These activities include exam style questions which will allow the students to assess their progress against the clearly explained answer. There is also a quiz that runs throughout the course of the lesson and this has been designed to maintain engagement and motivation. The following specification points have been covered in this lesson: Recall and use the equation to calculate the gravitational potential energy Recall and use the equation to calculate the kinetic energy Explain what is meant by the conservation of energy Explain that mechanical transfers become wasteful when energy is dissipated to the surroundings Explain ways of reducing unwanted energy transfers Recall and use the equation to calculate efficiency Describe the main energy sources available for use on Earth and explain their patterns and trends in the use of energy resources

The AQA specification states that a minimum of 10% of the marks across the 3 assessment papers will require the use of mathematical skills. This revision lesson has been designed to include a wide range of activities that challenge the students on these exact skills because success in the maths in biology questions can prove the difference between one grade and the next! Step-by-step guides are used to walk students through the application of a number of the formulae and then exam-style questions with clear mark schemes (which are included in the PowerPoint) will allow them to assess their progress. Other activities include differentiated tasks, group discussions and quick quiz competitions such as “FROM NUMBERS 2 LETTERS” and “YOU DO THE MATH”. The lesson has been written to cover as much of the mathematical requirements section of the specification as possible but the following have been given particular attention: Hardy-Weinberg equation Chi-squared test Calculating size Converting between quantitative units Standard deviation Estimating populations of sessile and motile species Percentages and percentage change Cardiac output Geometry Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2/3 hours of A-level teaching time to work through the activities and it can be used throughout the duration of the course

This revision lesson has been designed to challenge the students on their use of a range of mathematical skills that could be assessed on the AQA GCSE Combined Science papers. The mathematical element of the AQA GCSE Combined Science course has increased significantly since the specification change and therefore success in those questions which involve the use of maths can prove to be the difference between one grade and another or possibly even more. The engaging PowerPoint and accompanying resources contain a wide range of activities that include exam-style questions with displayed mark schemes and explanations so that students can assess their progress. Other activities include differentiated tasks, class discussion points and quick quiz competitions such as “YOU DO THE MATH” and “FILL THE VOID”. The following mathematical skills (in a scientific context) are covered in this lesson: The use of Avogadro’s constant Rearranging the formula of an equation Calculating the amount in moles using mass and relative formula mass Calculating the relative formula mass for formulae with brackets Using the Periodic Table to calculate the number of sub-atomic particles in atoms Changes to electrons in ions Balancing chemical symbol equations Converting between units Calculating concentration in grams per dm cubed and volumes of solutions Calculating size using the magnification equation Using the mean to estimate the population of a sessile species Calculating percentages to prove the importance of biodiversity Calculating percentage change Calculating the acceleration from a velocity-time graph Recalling and applying the Physics equations Understanding prefixes that determine size Leaving answers to significant figures and using standard form Helpful hints and step-by-step guides are used throughout the lesson to support the students and some of the worksheets are differentiated two ways to provide extra assistance. Due to the detail of this lesson, it is estimated that it will take in excess of 3 hours of GCSE teaching time to cover the tasks and for this reason it can be used over a number of lessons as well as during different times of the year for revision.

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content in topics C1 - C4, that will assessed on PAPER 3.
