This resources provides a fun and colourful introduction to enzymes. It is both a useful visual aid and includes past paper questions for students to answer. The resource defines enzymes as biological catalysts, made of protein, and breaks this definition down so that it is easy to understand. It introduces the lock and key theory as well as denaturation.

This resource introduces diffusion and the factors that effect the rate of diffusion, in a fun and interactive way. The lesson includes a simple experiment to test how temperature effects the rate of diffusion.

This resource introduces a series of experiments relating to the reactants and products of photosynthesis. The experiments provide evidence that carbon dioxide, chlorophyll and sunlight are required for photosynthesis to occur, and that oxygen and glucose are produced.

This resource introduces standard form, what it is and why it is useful. It includes a useful link to an animation on the topic, and questions with answers to give students practice on writing numbers in standard form.

This PowerPoint resource provides a useful visual aid for a lesson on the discovery and structure of DNA. It includes activities, questions and video links. I usually begin the lesson by inviting students to write down everything they already know about DNA in a black pen. I then introduce Watson and Crick, and the structure of DNA, using all the key terms on the slide. I then give my students minutes to answer the 6 mark question on the structure of DNA. Students then self-mark their answer using the mark scheme included in the PowerPoint, and show me on their fingers how many marks out of 6 they achieved for the question. If students have access to their own laptops I then invite students to watch a few of the video links that go into slightly greater detail about the structure of DNA. At the end of the lesson I ask the students to return to the list they made at the beginning of the lesson about everything they already knew about DNA. I invite the students to spend a couple of minutes adding to their list in a green pen with everything they now know about DNA.

This provides a useful visual resource, with written summaries, of the main stages in transcription and translation. I use it with my lower ability students who benefit from visual stimuli, as it goes through the processes step by step.

The following resource provides a helpful scaffold for students when designing, completing, recording, analysing and evaluating science experiments. I change the image and question on the first slide, depending on the experiment I plan on carrying out with my class. The second and third slides remain the same every time. This resource is adaptable, easy to use, and appropriate for KS3 and KS4 students.

This easy to use resource provides a useful visual aid and series of activities to help students understand the levels of organisation in multicellular organisms.

This creative resource introduces the structure and function of the lungs. It includes useful activities that are engaging for students and helps them master the topic.

This resource encourages students to research the human genome project. It includes a series of questions to guide their research as well as answers to the questions.

This resource provides an easy to use visual aid for a lesson introducing muscles, joints and antagonistic muscles.

This resource considers four factors that effect the rate of an enzyme-catalysed reaction: temperature, pH, concentration of enzyme, and concentration of substrate. This resource includes enough information and visual aids to fill 2 or 3 lessons. When I teach this topic, my students carry out a simple experiment, looking at the rate of hydrogen peroxide decomposition, to provide experimental evidence for the effect of pH and temperature on enzyme (catalase) activity.

This resource introduces thermoregulation and the actions or behaviours that increase or decrease heat loss. The resource includes a quick quiz and activity intstructing students to produce an A4 summary diagram explaining thermoregulation in humans.

This resource begins by introducing stem cells and their uses, before inviting students to write a clearly balanced account of the arguments surrounding the use of stem cells in research. It then moves on to introduce designer babies and encourages students to write a clearly balanced account of the arguments surrounding designer babies. This lesson provides excellent opportunities for class discussions on ethically challenging topics and an opportunity for students to complete extended pieces of writing. The resource includes links to useful videos on the topic.

This resource begins with a useful visual to introduce the topic of mutations and initiate discussion on point mutations. Students are then invited to watch two videos (links provided) before researching and answering a series of questions about mutations. I usually allow 20 minutes for the students to answer the questions on the worksheet, before going through the answers as a class (using the PowerPoint slides). If there is time, I then explain how mutations in bacteria enable them to become resistant to antibiotics.

This two slide PowerPoint resource provides a simple and easy to use stimulus for a lesson on reducing our carbon footprints. It includes a couple of useful web links and encourages students to complete their own carbon footprint reduction plan.

This creative, fun and easy-to-use resource introduces the process of diffusion. It includes a fun starter and plenary, useful video link and framework for a simple diffusion experiment.

This resource introduces the structure of the heart and double circulatory system. The second slide can be used both to introduce the different parts of the heart or as an assessment-for-learning activity at the end of the lesson. The third slide includes a worksheet that can be printed off and handed out to the students, for them to complete before the heart dissection. I usually project the fourth slide during the heart dissection to help students identify the different parts of the heart as they carry out their dissections. If there is time at the end of the lesson, I introduce the double circulatory system via an active learning activity, where students circulate around the classroom, holding either blue or red counters to represent deoxygenated and oxygenated red blood cells.
