A revision session designed to recall information on biological molecules - Water, Carbohydrates and Triglycerides

Specification link: 1.5 know how triglycerides are synthesised and describe the difference between saturated and unsaturated lipids A complete lesson promoting independent learning. I have provided 2 videos that students watch and extract relevant information to complete a worksheet. I suggest it is printed on A3 paper. Teacher - student discussion over main points ensures an understanding of the topic. A quiz of exam questions with a time limit.

Specification link: 1.2 (b) relate the structures of polysaccharides to their role in providing and storing energy A lesson designed to promote independent learning. There is a video students use the video to extract information about amylose and amylopectin and the difference in structure. Students find out independently how each molecule can be broken down to release energy. Exam circus of questions to work through with a partner. Check points provided after each task to ensure learning/correct information collected.

Specification link: 1.2 (a) know the differences between monosaccharides, disaccharides, polysaccharides including glycogen and starch In this lesson, students will learn the structures of common monosaccharides and how they combine in a condensation reaction to form disaccharides. Polysacchrides are mentioned briefly but they are studied in more detail next lesson (spec link 1.2 b) There are opportunities for independent learning as students determine the structure of monosaccharides and practice drawing the reaction between common monosaccharides labelling the bond and type of reaction. I have included an exam question for practice.

A PPT complete lesson which focuses on specification link: 1.1 understand the importance of water as a solvent in transport, including its dipole nature The power point includes independent learning activities where students must find what a dipole molecule is. There is a boardworks slide to explain what a solvent is and students use this to form their notes. Please note, this is an interactive slide and you must have enabled macros on PPT and have update flash for it to work. The terms cohesion and adhesion are introduced. I have included a brief exam question which links directly to the spec link.

A series of questions focused on the scientific article for the IAL Edexcel exam - unit 5. There is a teacher answer sheet included. I have also included a copy of the Scientific Article from Edexcel Unit 5 Exam and definitions for vocabulary. I have focused on the following topics: • The nervous system – structure and function of each neurone • Action potentials and how an impulse is generated • Synapses • Structure and function of areas of the brain • FMRI scans • The eye • Brain injuries • Critical window • Respiration • PCR and Gel electrophoresis • Speciation This resource helps student´s to focus their revision in the appropriate areas and help develop their exam response.

A power point to aid students understand how vaccination results in the manufacture of memory cells which enable future antibody production to the pathogen to occur sooner, faster and in greater quantity. I have used a range of resources throughout the PPT. There are 2 video which can prompt discussion. The first is a starter activity which reflects on the previous lesson, looking at the function of phagocytes and lymphocytes. Students are then introduced to the idea of vaccinations both by discussion and a video. There is a card sort activity to put the process in order and then a graph analysis task.

A whole lesson dedicated to looking at the effect of certain illegal substances and the ethical issues associated with drug taking in sports. I have included a debate where students sort through different opinions on drug taking in sports. This will help them formulate a for and against argument. I have also included information about how peptide and steroid hormones act as transcription factors and can activate protein synthesis. Finally, I have included the edexcel article from 2015 on drugs in sport and students can work through the article and answer the questions for homework.

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.

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 formative assessment task which can take 2 lessons or be set as a homework. I set this before the end of topic test to allow students time to clarify the ideas behind the unit. Students can use their text books and tablets but the work must be explained in their own words. I have included the criteria to include in the poster and the mark scheme which would be used to grade the work. This works well as a peer assessment as well as a teacher assessed task.

A power point full lesson allowing students to understand the role of photosynthesis in producing glucose for energy storage. Student should be able to understand the process of photosynthesis and its importance in the conversion of light energy to chemical energy Write a word and balanced symbol equation for photosynthesis Describe adaptations of a leaf for efficient photosynthesis There is a six mark exam question and mark scheme for self/peer 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.

A lesson which explores the effect of exercise and heart rate on the body. Students learn how to calculate cardiac output. The power point explores the role of the cardiovascular control centre. Students complete a diagram showing how both the sympathetic and parasympathetic nervous systems can increase/decrease the heart rate depending on blood pressure, need for oxygen and glucose. There is a little practical activity when students observe the effect of adrenaline on heart rate and how quickly heart rate changes.

A lesson to introduce the concept of covalent bonds through PPT and animation. Students learn the rules of how to draw dot cross diagrams to represent covalent bonds and apply their knowledge to draw hydrogen chloride, chlorine, oxygen, ammonia, methane, ethane, ethene, water and carbon dioxide.

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 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 complete lesson with worksheets and exam questions/answers which introduces the reflex arc. There are simple animations which show the route of the impulse. Synapses are not covered in detail as they are not needed for double award syllabus (edexcel IGCSE).

A lesson which introduces the idea of electrical activity in the heart, including the roles of SAN; AVN and bundles of His. It also includes how to interpret an ECG. This a complete lesson - possibly could take 2 lessons. It contains worksheets, video clips and exam questions. All answers provided in PPT so students can self assess their own work.

A PPT which includes all the activities of the lesson. Starter activity - students watch a brief video of sprinting and discuss what type of muscle fibres are likely to be present. The presentation takes them through the process of anaerobic respiration and there are check points along the way which promote discussion and check understanding. Finally, exam questions and mark scheme for self/peer assessment.
