This is a fully-resourced lesson that looks at the functional and structural differences between the transport tissues in a plant, the xylem and phloem. The lesson includes an engaging lesson presentation (41 slides), which includes numerous student-led tasks, progress checks and quick competitions and two question worksheets, one of which is a differentiated version to enable those students who are finding this topic difficult to still be able to access the learning. The lesson begins with the introduction of the two tissues as well as a brief introduction to the substances which they each carry. The next part of the lesson focuses on the xylem cells and the resulting xylem vessel, and key terms such as lignin are brought into the lesson so that students can understand how these cells are waterproofed, which causes them to decay and form hollow tubes. Having met a lot of information, students are challenged to act like an examiner to form a table based question to compare the xylem against the phloem where they have to come up with features which could be compared against. This table will form the backbone of the lesson and students will use it later in the lesson when they have to write summary passages about each of the tissues. Moving forwards, a quick competition is used to enable the students to meet the names of the cells that form the phloem tissue, the sieve tube elements and the companion cells. Students will see how they are involved in the functioning of the phloem and questions are posed which relate to other topics such as the involvement of mitochondria wherever active transport occurs. Progress checks like this are found at regular intervals throughout the lesson so that students can constantly assess their understanding. This lesson has been designed for GCSE students. If you are looking to teach about these tissues but to a higher standard, you could use my uploaded alternative called Xylem and Phloem (A-level)

This revision lesson contains an engaging powerpoint (45 slides) and associated worksheets that are incorporated into the lesson to challenge and consolidate the learning. The lesson has been designed to contain a wide range of activities so that students remain motivated and engaged whilst they assess their understanding of the content found in Biology topic 3 (Infection and response) of the AQA GCSE Combined Science specification (Trilogy 9-1) The exam questions, differentiated tasks and quiz competitions found within the lesson challenge the following specification topics: Communicable (infectious) diseases Viral diseases Bacterial diseases Fungal diseases Protist diseases The Human defence system Vaccinations Antibiotics Students will be able to use the lesson to identify the areas of the specification that require further attention and this lesson can be used at the end of the topic, in the lead up to the mocks or in the lead up to the actual GCSE exams.

The topics tested within this lesson include: Exchange surfaces Mammalian gaseous exchange system Tissues in the gaseous exchange system Transport in animals Blood vessels Exchange at the capillaries ECG Transport of oxygen Transport in plants Transport tissues Movement of water through plants Transpiration Translocation Student will enjoy the range of tasks and quiz rounds whilst crucially being able to recognise any areas which require further attention

A fully-resourced lesson which looks at how the sex chromosomes which determine gender are inherited in humans. The lesson includes an engaging lesson presentation (24 slides) and an associated worksheet containing knowledge recall and application questions. The lesson begins with a range of different quiz competitions which enable the students to get the answers of X, Y, zygote and 23. With a little bit of assistance, students are challenged to bring these terms together to complete a passage about how the inheritance of either an XX genotype will lead to a female or a XY genotype will lead to a male. Moving forwards, students are told how they will be expected to be able to construct a genetic diagram to show the inheritance of gender and so are given a quick recap before being challenged to do just that. The last part of the lesson gets students to discuss and consider whether females or males are responsible for determining sex in terms of their gametes. 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 primarily but the content is suitable for both KS3 and even A-level students

An engaging lesson presentation (39 slides) with associated differentiated worksheets that looks at they key differences between pure and impure substances and briefly explores how a mixture like an alloy can still be very useful. The lesson begins by challenging the students to recognise 4 diagrams of pure substances from a selection of 5. This will lead students to the definition of pure (in Science) which is likely to be different to what they have encountered in everyday language. The next task gets the students to draw a graph showing the melting and boiling points of pure water. This will enable them to compare the melting point against that of an impure substance and therefore recognise that this difference can be used as point to decide on purity. An example of gritting is used to explain how this change in melting point can be utilised and then the students are challenged to apply this new-found knowledge to the situation of adding salt to boiling water when making pasta. The remainder of the lesson focuses on some famous mixtures. Beginning with air, students will be able to visualise how this mixture is made of a number of gases, each with different boiling points which allows them to be separated by fractional distillation. Alloys are briefly explored so that students know why these mixtures are used for certain functions over pure metals and the summary passage for this task has been differentiated two ways so that all can access the work. Progress checks have been written into the lesson at regular intervals so that students can check their understanding and a range of quick quiz competitions are used to maintain engagement whilst introducing new terms in a fun manner. If you want to look into alloys in greater detail, then this lesson could be combined with the one named “alloys” which is also uploaded.

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 a concise REVISION lesson that contains an engaging powerpoint (43 slides) and associated worksheets. The lesson uses a range of activities which include exam questions (with displayed answers), differentiated tasks and quiz competitions to engage students whilst they assess their knowledge of the content that is found within topic P8 (Space Physics) of the AQA 9-1 GCSE Physics specification. The following sub-topics in the specification are covered in this lesson: Our Solar System The life cycle of a star Natural satellites Red-shift This lesson can be used throughout the duration of the GCSE course, as an end of topic revision lesson or as a lesson in the lead up to mocks or the actual GCSE exams

This engaging lesson looks at the structure of the quaternary protein, haemoglobin, and describes its role with red blood cells in the transport of oxygen. The PowerPoint has been designed to cover the first part of point 3.4.1 of the AQA A-level Biology specification and explains how the cooperative nature of binding results in a loading of each molecule with 4 oxygen molecules and describes how it is unloaded at the respiring cells too. 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. Students will learn that a conformational change upon binding of the first oxygen leads to it being easier to bind future oxygens and that this is known as cooperative binding. This lesson has been written to tie in with the other uploaded lesson on the Bohr effect.

This fully-resourced lesson describes the differences between continuous and discontinuous variation and intraspecific and interspecific variation. The engaging PowerPoint and accompanying resources have been designed to cover the first part of point 4.2.2 (f) of the OCR A-level Biology A specification but also acts as a revision tool as a number of activities challenge the students on their knowledge of the genetic code and meiosis from modules 2.1.3 and 2.1.6. The students begin the lesson by having to identify phenotype and species from their respective definitions so that a discussion can be encouraged where they will recognise that phenotypic variation between members of the same species is due to both genetic and environmental factors and that this is known as intraspecific variation. The next part of the the lesson focuses on these genetic factors, and describes how mutation and the events of meiosis contribute to this variation. A range of activities, which include exam-style questions and quick quiz rounds, are used to challenge the students on their knowledge and understanding of substitution mutations and deletions, the degenerate and non-overlapping genetic code, crossing over and independent assortment. Another quick quiz round is used to introduce polygenic inheritance and the link is made between this inheritance of genes at a number of loci as an example of continuous variation. In the following task, the students have to determine whether a statement or example represents discontinuous or continuous variation. The final part of the lesson describes a few examples where environmental factors affect phenotype, such as chlorosis in plants.

This lesson describes the differences between the primary and secondary responses and describes how the structure of antibodies is related to function. The PowerPoint and accompanying resources have been designed to cover specification points 4.1.1 (g), (h) and (i) as detailed in the OCR A-level Biology A specification and emphasises the importance of memory cells. As memory B cells differentiate into plasma cells that produce antibodies when a specific antigen is re-encountered, it was decided to link the immune responses and antibodies together in one lesson. The lesson begins by checking on the students incoming knowledge to ensure that they recognise that B cells differentiate into plasma cells and memory cells. This was introduced in a previous lesson on the specific immune response and students must be confident in their understanding if the development of immunity is to be understood. A couple of quick quiz competitions are then used to introduce key terms so that the structure of antibodies in terms of polypeptide chains, variable and constant regions and hinge regions are met. Time is taken to focus on the variable region and to explain how the specificity of this for a particular antigen allows neutralisation and agglutination to take place. The remainder of the lesson focuses on the differences between the primary and secondary immune responses and a series of exam-style questions will enable students to understand that the quicker production of a greater concentration of these antibodies in the secondary response is due to the retention of memory cells.

This fully-resourced lesson explores the contributions of the chromosome mutations that arise during meiosis to genetic variation. The engaging PowerPoint and accompanying worksheets have been designed and written to cover the part of point 4.3 of the AQA A-level Biology specification which states that students should be able to describe how mutations in the numbers of chromosomes can arise spontaneously and significantly contribute to evolution. Over the course of the lesson, students will encounter a number of chromosome mutations but the main focus is chromosome non-disjunction and they will learn that this can result in Down, Turner’s and Klinefelter’s syndromes. Students are guided through a description of the formation of gametes and zygotes with abnormal numbers of chromosomes before being challenged to describe the formation of a zygote with Turner’s syndrome. The key aspects of meiosis, which are taught in a future lesson, are introduced and related to the lead up to the change in chromosome number. Inversion, translocation, duplication and deletion are also introduced and links are made to other topics such as regulatory sequences and gene expression.
