A fully-resourced lesson which guides students through using moles to calculate the mass of a substance in a reaction. The lesson includes a detailed lesson presentation (22 slides) and associated worksheets which are used to check the skills and understanding of the students. The lesson begins by introducing the students to the three steps involved in a calculating mass question. These skills include calculating the relative formula mass and identifying molar ratios in equations to calculate amounts so time is taken to recap on how this is done before students are given the opportunity to try some progress check questions. A worked example brings these three steps together to guide the students to the final answer. The final task involves 4 questions where students are challenged to apply their new-found knowledge. This lesson has been written for GCSE students (14 - 16 year olds in the UK)

A fully-resourced lesson, which has been designed for GCSE students, and includes an engaging and informative lesson presentation (37 slides) and differentiated worksheets. This lesson explores the type of cell division known as meiosis and focuses on the use of key terminology so that students can apply their knowledge to any organism that carries out this division, and not just humans. For this reason, time is taken at the start of the lesson to go over the meaning of the terms, diploid and haploid. Students are also taught how to think about the quantity of DNA inside a cell in terms of n, so that they can see and understand how this quantity changes through the cell cycle. They are encouraged to fill in a table at each stage of the cycle to show the quantity of DNA. In this way, students will understand how a diploid parent cell goes through interphase and as a result of DNA replication, the quantity of DNA is 4n as the first meiosis division is about to start. Although this could be viewed as high end knowledge, the format of this lesson should allow all abilities to understand and therefore have more chance of being successful with meiosis questions. Students are encouraged to think for themselves to work out how many daughter cells will result at the end of two divisions and to consider the quantity of DNA found inside those cells. At this stage of the lesson, students have to summarise all they have learnt into two key points (as shown on the cover image). The remainder of the lesson gives them the opportunity to apply their knowledge with a range of questions and it is not until right at the end that they are allowed to finally relate this cell division to humans. Although this lesson has been primarily designed for GCSE students (14 - 16 year olds in the UK), it is highly suitable for A-level lessons, especially if a teacher wants to recap on this cell division before extending knowledge.

This is a fun and engaging lesson that uses a range of quick competitions and tasks to ensure that the students recognisethe electrical symbols for the essential components and can describe the functions for each of these. Competitions such as SNAP and SAY WHAT YOU SEE will introduce the students to the components and their symbols. This lesson has been written for GCSE students and looks to build on what they should know from KS3 - however, it could be used with higher ability students at that level.

This detailed and engaging lesson uses a range of tasks, discussion points and quick competitions to explore how the structure of metals is related to their properties. The lesson begins by providing the melting points for four metals and challenging the students to work out why mercury would be considered to be the odd one out. This task enables students to recognise that most metals are solid at room temperature and then the next part of the lesson guides students through explaining how this is related to the structure. The range of quick competitions are used to maintain engagement but also to introduce new terms such as lattice and delocalised so that students can recognise these in descriptions and use them accurately in their own. Students will recall that metals are good conductors of electricity and heat and now will be able to explain this with reference to the free electrons. Progress checks are written into the lesson at regular intervals so understanding can be checked at critical points and misconceptions addressed. The final part of the lesson makes link to related topics such as alloys and naming compounds. This lesson has been written for GCSE aged students.

This fully-resourced lesson describes the use of vaccinations to protect individuals and populations and the differences between active and passive immunity. The engaging PowerPoint and accompanying resources have been designed to cover the fourth part of point 2.4 of the AQA A-level Biology specification and there is also a description and discussion on the concept of herd immunity. The previous lesson finished with a series of exam questions where students observed differences between the primary and secondary immune responses so the start of this lesson uses an imaginary game of TOP TRUMPS to challenge them on the depth of their understanding. This will act to remind them that a larger concentration of antibodies is produced in a quicker time in the secondary response. The importance of antibodies and the production of memory cells for the development of immunity is emphasised and this will be continually referenced as the lesson progresses. The students will learn that this response of the body to a pathogen that has entered the body through natural processes is natural active immunity. Moving forwards, time is taken to look at vaccinations as an example of artificial active immunity. Another series of questions focusing on the MMR vaccine will challenge the students to explain how the deliberate exposure to antigenic material activates the immune response and leads to the retention of memory cells. A quick quiz competition is used to introduce the variety of forms that the antigenic material can take along with examples of diseases that are vaccinated against using these methods. The eradication of smallpox is used to describe the concept of herd immunity and the students are given time to consider the scientific questions and concerns that arise when the use of this pathway is a possible option for a government. The remainder of the lesson looks at the different forms of passive immunity and describes the drawbacks in terms of the need for a full response if a pathogen is reencoutered.
