A PDF worksheet of a dichotomous key to identify invertebrates. This can be used as an independent learning task where students can work through the clues in the key. Answer sheet included.

PDF worksheets which covers both the light dependent and independent reactions. Students refer to a diagram of both processes to answer exam style questions. Suitable for revision, retrieval activities and homework. Answer sheet included.

A PPT with complete lesson with different activities to introduce the idea of surface area and volume and how it is affected by the size of an organism. Activities include - calculating the surface area and volume of 3 cubes; explaining why certain cells/organs have a large surface area. There is also an edexcel IGCSE exam question and mark scheme for self assessment.

A PPT which introduces the role of both xylem and phloem. The first activity is a research activity (8 minutes) where students use resources available to determine characteristics and roles of phloem and xylem. The next 20 minutes is a circus of activities with microscope work (drawing xylem and phloem); observing dye in celery; dendrochronology (tree rings) and transpiration and translocation.

This series of 3 lessons covers: the terms magnification and resolution the differences between light and electron microscopes the importance of staining in microscopy; a series of practicals with instructions how to make plan drawings of specimens how to use a graticule. I have included different tasks, some individual and some group work. I have encouraged my students to study independently rather than give all of the information. There are also a series of exam questions to test understanding. These lessons provide support towards the core practical

We have started using this technique in our science department to allow students to highlight areas where they make mistakes. This could be due to misreading questions; not understanding the material; not understanding the questions; calculation questions or not using correct terminology. Once our students were aware of where the mistakes were being made, we gave them focused targets and it has helped improve their performance.

This resource focuses on Edexcel specification link 6.11 It introduces the different types of immunity. There is a video resource and questions to check understanding. The information cards can be printed and put around room for students to collect information to make it more interactive. I was short on time so I went through them on the board as students made their own notes.

2 lessons focusing on Edexcel specification link 2.7 The first lesson is an introduction to enzymes and naming enzymes The second lesson focuses on how they work and factors which affect the rate of reaction.

A level Biology - Control of the Internal Environment 4 Powerpoint lessons covering: The principles of mammalian hormone production by endocrine glands The mode of action of hormones The production of metabolic waste Osmoregulation Kidney structure and function Urea production Thermoregulation

An activity to introduce the main elements of the transport topic or to be used as a revision tool. I have used it in class but it can be used for home schooling assignment or homework. The activity took my students over an hour. There are many tasks the students must complete as they collect their clues. Students need access to the internet to carry out this activity.

Exam-style questions on the menstrual cycle to check student understanding of the topic. Answer sheet included.

2 worksheets focusing on the role of carbohydrates in biological organisms including how they are formed and the different structures they form. Monosaccharides, disaccharides and polysaccharides. Exam-style questions and answers included.

A pdf worksheet focusing on the experiment with water plants with and without light. Also contains respiring organisms. The experiment uses bicarbonate indicator which changes colour in the presence of low and high concentrations of carbon dioxide. The experiment is explained and there are exam-style questions to promote understanding. Answer sheet included. Suggested uses: in class activity; homework task; revision task

This is an interactive lesson focusing on the different methods used by forensic scientists to determine the time of death. This includes: Algor mortis (body temperature) Rigor mortis (muscle contraction) Livor mortis (colour of skin after death) Entomology (study of insects) Decomposition Students click on each link to gain information about each method. The information is in the form of text, diagrams and videos. Students can summarise this information in their notes if the teacher wishes. The students are then given information about 5 deceased people and the state of the body when found. Working in pairs or groups, students use the information to predict and approximate the time of death (they are given a current time and work backwards).

A3 REVISION MATS FOR EDEXCEL BIOLOGY UNIT 5 SUITABLE FOR BOTH A LEVEL AND INTERNATIONAL A LEVEL. ANSWER SHEET INCLUDED. THESE RESOURCES HAVE HELPED MY STUDENTS LEARN THE TOPICS AND THEN APPLY THE KNOWLEDGE TO EXAM QUESTIONS. TOPICS INCLUDE: MUSCLE NEUROMUSCULAR JUNCTION TYPES OF FIBRE STRUCTURE OF A NEURONE CHANGES IN MEMBRANE POTENTIAL SYNAPSES AND NEUROTRANSMITTERS BRAIN STRUCTURE BRAIN SCANS BRAIN DISORDERS CONTROL OF HEART RATE CONTROL OF BREATHING RATE THERMOREGULATION

A Word document which can be modified. It contains all of the specification points for unit 4 “Energy Flow, Ecosystems and the Environment”. I have included an exam progression tracker for the 8 exams available and have included the grade boundaries and UMS scores for each exam. These are the modular exams for unit 4 IAL but are also great exam practice for Biology A students in preparation for the June exam. I have included page references for each specification point (from the IAL Book 2 and will need to be modified for Biology A). There is also a RAG section to support student learning. I print these and give them to each student so they can follow the course but also monitor their performance in each exam.

This is a 2 part lesson for muscle contraction. It introduces actin-myosin interactions in the sliding filament theory. I have included some PPT slides from boardworks which highlight this interaction very well. I have also included 2 videos from youtube which I find very helpful. The crash course video can be used in either lesson 1 or 2. The Biology ATP Myosin video is a resource I use along slide the boardworks presentation on muscle contraction where students use both resources and their books to produce a flow chart or bullet points explain what occurs in the sarcomere. There is also an exam question at the end of lesson 2. *please note that you will need to enable macros on PPT to allow boardworks to be interactive

This PPT introduces the idea that it is difficult to assess the relative contribution of both genes and the environment to disease. It introduces some examples of how genes and the environment interact e.g. siamese cat colour; oncogenes. This lesson is for promoting class discussion rather than many individual activities. I have included an exam question and mark scheme in the PPT This is an A level lesson but would be suitable for a high ability GCSE to promote discussion.

A whole lesson plan allowing students to discover the structure and function of the eye. This lesson is following the double award IGCSE for Edexcel and students need to describe the structure and function of the eye. I have not included information about accommodation. This lesson is a lovely introduction to the eye and includes an eye dissection task plus a 3D image starter activity; exam question and brief investigation into the response to bright light.

A power point which introduces the structure and function of the parts of a flower. Students then analyse the differences between the insect and wind pollinated flowers. There is a brief explanation of fertilisation and formation of the pollen tube. Finally looking at asexual and sexual reproduction in plants. The power point contains the whole lesson and it is easy for the teacher to follow the plan of the lesson with tasks for students clearly highlighted and check points to ensure learning. I have used a ppt slide from the author clickbiology as I think it is one of the best slides on flower structure I have seen.
