An informative and student-led lesson presentation (32 slides), accompanied by a reaction diagram and task worksheet, which together look at the key details of nuclear fission reactions. The lesson begins by introducing the students to the name of this reaction and to that of a neutron before they are challenged to recall the properties of this sub-atomic particle as this knowledge plays an important role in their understanding. Moving forwards, students will learn that two isotopes of uranium are involved and will discover and work out how one isotope is changed into the other. Diagrams accompany the theory throughout so that students can visualise how the reaction progresses. They are shown how to work out the two daughter nuclei that are produced in the reaction and how an equation can be written to represent nuclear fission. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be immediately addressed. This lesson has been designed for GCSE students (14 - 16 year olds in the UK)

This lesson has been written for GCSE students and aims to ensure that they can explain in detail why light changes direction due to refraction. The key to the explanation is the use of the correct terms in context so the start of the lesson challenges the students to come up with the key words of light, bend, normal, density and speed when given a range of clues. The next part of the lesson works with the students to bring these key terms together to form a definition of refraction. Moving forwards, the relationship between density of a medium and the speed of light through that medium is discussed so that there is a clear understanding of why light bends one way or the other. The next task uses the definition to apply to a practical situation to draw a diagram of light moving from air to glass. The final part of the lesson involves a range of practicals so this topic can be explored further.

A concise, fast-paced lesson that looks at the orbits of both natural and artifical satellites. The lesson has been written to build on the student’s knowledge of space from KS3 and add key details such as the gravitational pull between the different celestial objects. Students will learn how the speed of the orbiting object and the gravitational pull ensure that the object remains in orbit and consider what would happen should the speed change. Students are briefly introduced to a number of orbits of artificial satellites as well as the uses. This lesson has been designed for GCSE students

This lesson has been designed to explore the range of energy sources which are used on Earth and specifically looks at why an increase in the use of renewable sources is critical for the future. The student’s scientific understanding is challenged at each step of the lesson but there is also a mathematical element running throughout. The lesson begins by challenging the students to predict which energy sources contributed the greatest % when presented with a pie chart. Students cover this topic in other subjects like Geography, so the lesson aims to build on this and consolidate the essential understanding. A range of renewable sources are discussed and key terms such as carbon-neutral taken on further. This lesson has been designed for GCSE students but parts could be used with younger students who are looking at

This is a fully-resourced lesson that looks at the role of transformers in the National Grid, explains why they increase or decrease potential difference and then uses the given equation to calculate potential difference or the number of turns on the primary or secondary coil. This lesson includes an informative lesson presentation (25 slides) and two question worksheets. The lesson begins by introducing the devices that are transformers and showing the students that there are two types, step-up and step-down. Students will learn that step-up transformers increase the potential difference and step-down transformers decrease the potential difference. Moving forwards, a series of calculations are used to get the students to understand why these changes in potential difference occur. Students are guided through this section so that they are able to complete a summary passage about the roles of these devices. They will then be shown the equation connecting potential difference and number of turns which they do not need to recall but have to apply. Again, a worked example is used to visualise how workings should be set out before students are challenged to answer two sets of questions, the second of which involves the use of a second equation. Progress checks like these are found at regular intervals throughout the lesson so that students can assess their understanding. This lesson has been written for GCSE students

This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams

An engaging lesson presentation (30 slides) that looks at electric current and ensures that students know the key details about this factor in preparation for their GCSE studies. The lesson begins by forming a definition for this electrical term and then as the lesson progresses, this definition is broken so that each element is understood. Students will be introduced to the difference between electron flow and conventional current. Time is taken to ensure that students understand that an ammeter must be set up in series. The remainder of the lesson will focus on the mathematical calculations which include current and important skills such as converting between units is covered.] As stated above, this lesson has been designed primarily for those students taking their GCSE exams (14 - 16 year olds in the UK) but is suitable for younger students too.
