This lesson explores how certain farming methods reduce biodiversity and considers the importance of a balance between conservation and farming. The PowerPoint and accompanying resources are the second in a series of 2 lessons which cover the detail in point 4.6 (biodiversity within a community) of the AQA A-level biology specification. The lesson begins by challenging the students to use the % change formula to calculate the predicted population in the UK by mid 2030. This increase to almost 70 million will lead into the recognition that farmers are under constant pressure to grow and provide enough food to feed this ever-growing population. A series of tasks and discussions will consider farming methods such as continuous monoculture and herbicides and insecticides which reduce biodiversity. This introduces conservation as active management to prevent the loss of biodiversity and several methods including the CSS and buffer strips are explored to encourage the students to think about the aims of these strategies. The other lesson covering specification point 4.6 is uploaded and named “biodiversity within a community”.

This extensive revision lesson challenges students on their knowledge and understanding of the content of topics 5 - 8 of the AQA A-level specification. The PowerPoint and accompanying resources are detailed and engaging and contain a selection of tasks which challenge the following points: Directional, stabilising and disruptive selection Saltatory conduction and other factors affecting conductance speed The structure of a motor neurone Sensory receptors, depolarisation and initiation of an action potential Hardy-Weinberg principle Genetic terminology Codominance and sex-linkage Autosomal linkage Chi-squared test Phosphorylation The stages of aerobic respiration Explaining lower ATP yields in anaerobic respiration Skeletal muscle contraction Structure and function of slow and fast twitch muscle fibres The control of heart rate Electrophoresis and genetic fingerprinting The secondary messenger model The students are tested through a variety of tasks including exam questions, understanding checks, and quiz rounds to maintain engagement. Due to the mathematical content in all A-level exams, there is also a focus on these skills. The answers to all questions are embedded into the PowerPoint so students can use this resource outside of the classroom. The delivery of the whole lesson will likely need at least 2 or 3 hours of contact time so this resource could be used with students in the final weeks building up to their paper 2 exam, or alternatively with students before their mocks on these topics.

An engaging lesson presentation (16 slides) which looks at the surface area to volume ratio and ensures that students can explain why this factor is so important to the organisation of living organisms. This is a topic which is generally poorly misunderstood by students and therefore time has been taken to design an engaging lesson which highlights the key points in order to encourage greater understanding. The lesson begins by showing students the dimensions of a cube and two answers and challenges them to work out what the questions were that produced these answers. Students are shown how to calculate the surface area and the volume of an object before it is explained how this can then be turned into a ratio. Time is taken at this point to ensure that students can apply this new-found knowledge as they have to work out which of the three organisms in the “SA: V OLYMPICS” would stand aloft the podium. Students are given the opportunity to draw conclusions from this task so that they can recognise that the larger the organism, the lower the surface area to volume ratio. The lesson finishes by explaining how larger organisms, like humans, have adapted in order to increase the surface area at important exchange surfaces in their bodies. There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been written for GCSE students but is perfectly suitable for A-level students who want to look at this topic from a basic level

An engaging lesson which looks at the properties of the Transition metals of the Periodic Table and ultimately compares these properties against other metals, such as the Alkali metals. Through the use of a range of motivating tasks and quiz competitions, students will learn that the transition metals form coloured compounds, have a number of ion charges, act as catalysts and are harder, stronger but less reactive than group 1. This lesson has been written for GCSE students (14 - 16 year olds) but is suitable for younger students who are looking at the patterns and trends in the Periodic Table

A fully- resourced lesson which looks at the chemical reaction that is anaerobic respiration and ensures that students can understand why this form of respiration can only be used for short periods of time. The lesson includes an engaging lesson presentation (39 slides), a newspaper article and application questions. The lesson begins by challenging the students to recall information about aerobic respiration to recognise that the sole reactant of anaerobic respiration is glucose. A newspaper article about two atheletes from the 10000m race has been written to challenge the students to recognise why one of the athletes wouldnt be able to compete again in the near future whilst the other could. As a result, students will be introduced to lactic acid and will learn how this poisonous substance prevents muscle contraction and causes cramps. Time is taken to ensure that students are familiar with ATP and specifically that they recognise that a much lower yield is produced in this type of respiration. A perfect opportunity is taken to get the students to carry out a mathematical calculation to compare the yields. Oxygen debt is discussed and related back to the original newspaper article. Finally, anaerobic respiration in plants and yeast is considered in terms of fermentation and the word and symbol equation is written so that it can be compared to those from animals. There are regular progress checks throughout the lesson to allow the students to check on their understanding. The lesson has been written for GCSE students but could be used with higher ability KS3 students or A-level students who want a recap before covering the topic in greater detail on their course.

An informative lesson presentation (37 slides) and associated question worksheet which looks at the key properties of alpha, beta and gamma radiation. Students are given key pieces of information during the lesson and are then challenged to use their knowledge of related topics such as atomic structure and waves to complete the information table about the types of radiation. By the end of the lesson, students will be able to compare the types of radiation on form, charge, relative mass, penetrating power and equation symbols. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding. This lesson has been written for GCSE students (14 - 16 year olds in the UK).

This is an engaging and informative lesson that looks at the group of unsaturated hydrocarbons known as the alkenes and focuses on a few properties, their displayed and chemical formulae and identification. This lesson has been designed for GCSE students and works nicely with the “alkanes” lesson as students can use learning from both lessons. The lesson begins by ensuring that students recognise a key difference between the alkenes and the alkanes in terms of the carbon-carbon bond. This shows them that there is no such substance as methane. They are guided through the rules of drawing alkenes, with examples of ethene and propene used so that they can then apply this technique to draw butene. Working together with the teacher, they will be able to write the general formula that connects this group of substances. The rest of the lesson focuses on the term unsaturated and how this affects them in terms of the identification test with bromine water as well reactions with hydrogen. The lesson finishes by getting students to recognise a use of ethene in making the alcohol, ethanol.

Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams. A lot of the tasks have been differentiated so that students of all abilities can access the work and be challenged appropriately.
