A task which is suitable for students in class but also during home schooling. It covers GCSE/IGCSE Photosynthesis specification looking at: photosynthesis equation limiting factors structure of the leaf mineral ions photosynthesis practicals The task is set as a spy mission. Students are directed to different websites which included images, videos and information. Students collect the information and use to complete a mission grid which helps them crack the code. In total there are 15 clues, building up their knowledge of photosynthesis. The PPT includes an answer sheet (remove from powerpoint before sharing with students!) My students loved this activity and it gave them a good introduction to photosynthesis.

A series of activities for students to complete in class or at home in preparation for the unit 1 examination. It is most useful to use before they attempt exam past papers. Resources include: A learning grid with focused questions to ensure students cover main topics in unit 1 (18 pages). This includes biological molecules; Heart and cardiac cycle; Blood transport system; CVD; Cell membranes; Movement across membranes; Gas exchange; Inheritance; DNA replication; Protein synthesis; Mutations Also with questions focused towards core practicals. Exam command words reminder

A series of activities for students to complete in class or at home in preparation for the unit 4 examination. It is most useful to use before they attempt exam past papers Resources include: A tick sheet for revision A learning grid with focused questions to ensure students cover main topics in unit 4 (11 pages). This includes photosynthesis; global warming; evolution; GPP and NPP; microorganisms and how they reproduce; the immune response; immunity ; PCR; DNA profiling and forensics. Vocabulary reinforcer Exam command words reminder

A series of lessons which support the Pearson textbook for the international AS level (edexcel). These resources are also useful for online lessons to aid student’s understanding at home. Covered in these lessons: The need for a circulatory system The importance of surface area to volume ratio The advantage of a double circulatory system The structure and function of blood The role of platelets in blood clotting The role of haemoglobin in transport of oxygen and carbon dioxide The structure of the heart and the cardiac cycle Atherosclerosis I have included different activities, some individual and some which could be within a group or with a partner. Plus exam questions and tasks to check understanding.

A series of lessons that students can complete in class or at home. It is an introduction to the first units studied and builds on previous knowledge learned at GCSE. Lessons include: Describe the structure of the atom and atomic particles Calculate mass number and atomic number Define the term isotope Explain what is relativity and why do we compare to carbon 12 Define relative isotopic mass, relative atomic mass, relative molecular mass and relative formula mass

A complete lesson which introduces the terminology used in Ecology lessons. We also explore how abiotic and biotic factors can affect a habitat. There are questions to check understanding of knowledge learnt plus independent learning activities. Learning outcomes Recall what is meant by the terms population, community, habitat and ecosystem Understand that the numbers and distribution of organisms in a habitat are controlled by biotic and abiotic factors Understand how the concept of a niche accounts for the distribution and abundance of organisms in a habitat

A level biology lesson exploring how a changing climate can lead to the evolution of a species. Learning outcomes Understand how evolution can come about through gene mutations and natural selection Understand how isolation reduces gene flow between populations, leading to allopatric or sympatric speciation This is a complete lesson which includes individual and group tasks for students. There are also exam questions to check understanding.

A level Biology lesson looking at the structure of ATP and its role in cells Lesson objectives: Describe the structure of the molecule ATP Explain why ATP is used by organisms Describe the role ATP plays in the cell There are a series of exam questions included to check understanding

A series of complete lessons covering the syllabus content for the IAL Biology topic 8B. This includes the structure and function of the mammalian nervous system. The structure of the spinal cord and brain. The peripheral nervous system How we investigate the structure and functions of the brain The effect of drugs on synapses Chemical control in plants Phytochrome and seed germination/flowering I have tried to include various methods for both independent and group learning. There are also short assessment questions to check understanding.

IAL Edexcel Topic 8A Included in this chapter: The structure and function of the mammalian nervous system Nervous transmission Resting and action potential Myelinated neurones and saltatory conduction Synapses Effects of drugs on synapse The detection of light Habituation Included in this selection of powerpoints are videos, exam questions plus tasks throughout the lesson to generate discussion and independent learning.

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

A series of lessons which focus on homeostasis and muscles. Students will study the structure of skeletal muscle Fast and slow twitch muscle fibres The sliding filament theory The role of actin, myosin and ATP The myogenic nature of the heart ECGs Homeostasis and negative feedback Control of heart and breathing rate

This series of lessons covers: The basic principles of cellular respiration The importance of cellular respiration in the production of ATP The site of glycolysis, krebs cycle and oxidative phosphorylation The main stages of glycolysis, Krebs cycle and oxidative phosphorylation. Anaerobic respiration Respiratory substrates and respiratory quotient. Each power point is a complete lesson which includes activities and exam style questions to check understanding.

Edexcel Specification 6.17 - 6.19 Two lessons which takes students through the process of how the polymerase chain reaction works and how gel electrophoresis can produces banding patterns. There are opportunities for class discussion and tasks for the students to complete. I have also included a video which discusses DNA fingerprinting.

Edexcel Spec Link - 6.16 and 6.20 Three lessons which focus on the forensic science element of the topic. The first lesson looks at the role of microorganisms in decomposition. This is a recap session, looking at the carbon cycle. Lesson 2 introduces the idea of using body temperature and rigor mortis to determine time of death. lesson 3 finishes the topic looking at the role of bacteria and insects in decomposition. This links to succession which had been studied previously. There are many different student activities including questions and answers on the topic.

Tow power point lessons which look at the action of antibiotics on bacteria - bacteriostatic and bactericidal. Also, how natural selection has made certain bacteria resistant to antibiotics and why this has occurred. There are activities for the students to promote active learning plus video resources and questions.
