A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

This lesson focuses on the nature of the genetic code in terms of being near universal, non-overlapping and degenerate and specifically focuses on this latter term to explain how a mutation may not result in a change to the sequence of amino acids. The PowerPoint has been designed to cover point 2.1.3 (f) of the OCR A-level Biology A specification and there are clear links to gene mutations which students will meet in module 6.
The lesson begins by introducing the terms near universal and non-overlapping in addition to degenerate. A quick quiz competition is used to generate the number 20 so that the students can learn that there are 20 proteinogenic amino acids in the genetic code. This leads into a challenge, where they have to use their prior knowledge of DNA to calculate the number of different DNA triplets (64) and the mismatch in number is then discussed and related back to the lesson topic. Moving forwards, base substitutions and base deletions are briefly introduced so that they can see how although one substitution can change the primary structure, another will change the codon but not the encoded amino acid. The lesson concludes with a brief look at the non-overlapping nature of the code so that the impact of a base deletion (or insertion) can be understood when covered in greater detail in module 6.
This engaging lesson looks at the role of haemoglobin in transporting oxygen and carbon dioxide and compares the dissociation curves for foetal and adult haemoglobin. The detailed PowerPoint has been designed to cover points 3.1.2 (i & j) of the OCR A-level Biology A specification and includes references to the role of carbonic anhydrase and the formation of haemoglobinic acid and carbaminohaemoglobin.
The lesson begins with a version of the quiz show Pointless to introduce haemotology as the study of the blood conditions. Students are told that haemoglobin has a quaternary structure and are challenged to use their prior knowledge of biological molecules to determine what this means for the protein. They will learn that each of the 4 polypeptide chains contains a haem group with an iron ion attached and that it is this group which has a high affinity for oxygen. Time is taken to discuss how this protein must be able to load (and unload) oxygen as well as transport the molecules to the respiring tissues. Students will plot the oxyhaemoglobin dissociation curve and the S-shaped curve is used to encourage discussions about the ease with which haemoglobin loads each molecule. At this point, foetal haemoglobin and its differing affinity of oxygen is introduced and students are challenged to predict whether this affinity will be higher or lower than adult haemoglobin and to represent this on their dissociation curve.
The remainder of the lesson looks at the different ways that carbon dioxide is transported around the body that involve haemoglobin. Time is taken to look at the dissociation of carbonic acid into hydrogen ions so that students can understand how this will affect the affinity of haemoglobin for oxygen in an upcoming lesson on the Bohr effect.
It is estimated that it will take in excess of 2 hours of A-level teaching time to cover the detail of these two specification points as covered in this lesson
This is a fully-resourced lesson that is written for GCSE students and focuses on the calculations associated with the numerous equations that electrical power is found in.

Their whole range of mathematical skills will be tested, including rearranging the formula, conversion between units and simplifying two equations into one. The understanding of each of these skills and equations is checked through a range of tasks, each of which has a displayed mark scheme and explanation at the end so that students can self-assess their understanding. Students are encouraged to discuss and come up with insightful questions and answers.

This is a fully-resourced lesson that looks at the different parts of the National Grid, specifically focusing on the roles of the step-up and step-down transformers. The lesson includes an informative lesson presentation (25 slides) and a calculations worksheet which challenges the students to apply their mathematical skills to work out why the potential difference is increased and decreased by the transformers. Time has been taken to make links to related topics such as electrical circuits as well as the conservation of energy. Students will recognise that a high current would have led to a lot energy being dissipated to a thermal energy store if step-up transformers weren’t involved and also that decreasing the potential difference before it enters the homes as mains electricity is important to reduce the risk of electrocution. A number of quick competitions are used to introduce key terms or to check on understanding such as ORDER, ORDER which is shown on the cover image where students have to recognise when the parts of the National Grid are finally shown in the correct order.
This lesson has been designed for GCSE aged students.

Students are guided through a method of calculating the surface area and volume of the object and calculating the surface area to volume ratio. Using the answers to their calculations, they will complete a summary passage which explains why having more exposed reacting particles leads to an increased rate of reaction. Students will then carry out a practical where they have to determine which cube of jelly to use to make jelly the fastest in order to test their summary passage is valid.
