This resource covers pyramids of biomass and calculating the efficiency of biomass transfer. It explains how pyramids of biomass are draw, why biomass decreases at each topic level, and the equation for calculating the efficiency of biomass transfer.

This resource explains the difference between pure and impure substances, challenges students to compare graphs of pure and impure substances, and explains what is happening at a particle level during heating. Students then complete a simple practical where they measure the temperature of a substance as they heat it and then use a graph of their results to conclude whether or not the substance was pure or impure.

This resource provides a useful visual aid for introducing and comparing the processes of meiosis and mitosis. The resource includes links to videos on the topic, questions for students to answer, and a true false quiz. One of the tasks instructs students to create a video, poster, or model on mitosis or meiosis. This activity could either be completed during lessons or as a homework.

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 resource provides an easy-to-use visual aid and activities on the structure of the eye and structure of the camera. It explains how the eye works and how the pinhole camera works, before challenging students to answer the 6 mark question “Compare the eye and the camera”. The resource includes a mark scheme for this question as well as additional questions that could be answered through investigations with a pinhole camera.

This PowerPoint provides a useful and easy-to-use visual aid for discussing the similarities and differences between molecules and compounds. It follows on from my ‘Atoms and Elements’ lesson (available on TES) and introduces the idea that compounds have different properties to the elements that make them up.

This PowerPoint provides a fun and easy-to-use introduction to forces, interactional pairs, contact and non-contact forces, and how forces are measured and represented.

This creative, fun and easy-to-use resource helps explain the difference between heat energy and temperature. It includes questions for students to answer and a link to a useful video on the topic.

This engaging and easy to use resource provides a useful visual aid for introducing the changes that occur in lungs during during inhalation and exhalation, how lung volume can be measured and the factors that effect it. If you have a bell jar model of the lungs available to you, then the lesson is supported well with a demonstration.

This creative and easy-to-use resource introduces leaf structure and function. It begins with a discussion about adaptions and the structures that make leaves specially adapted for their function. It includes cross-sectional diagrams through the leaf for students to label, before inviting students to design an experiment to investigate whether plants lose more water from the upper or lower leaf surface. It includes a writing frame to help support students as they design, carry out and evaluate their experiments, as well as a true or false quiz to finish.

This resource provides an incredibly useful visual aid for the topic of ‘colours of light’. It covers everything from refraction and dispersion, to colour filters and explanations for why objects appear differently in different colours of light.

This resource introduces the phrases of the moon and how solar and lunar eclipses form. It is an incredibly useful visual aid and includes a series of questions about eclipses for students to respond to.

This resource introduces the limiting factors and the factors that affect the rate of photosynthesis. Students describe and explain a series of graphs before discussing why greenhouses are used to optimise conditions for photosynthesis.

This resource introduces negative feedback in the context of the endocrine system, using the example of thyroxine and the thyroid gland.

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.
