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 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 resource introduces natural selection and three key examples of rapid changes in species brought about by evolution: bacterial resistance to antibiotics, pesticide resistance in insects, and the peppered moth before, during and after the industrial revolution. I use the first slide to introduce the process of natural selection. I then use an incredibly useful resource, available for download from TES on “sticky dogs”, which I get the class to evaluate. I then introduce the peppered moth example, before getting the students to complete the 6 mark past paper question to time. We go through the mark scheme to this question together before I introduce bacterial resistance and pesticide resistance. The students then complete the tasks set on the final slide.

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.

This resource covers the control of blood sugar and what happens if you are unable to produce enough insulin. It includes useful links to animations on blood glucose control and questions for students to answer.

This resource introduces the water cycle, the key terms relating to the water cycle, and how polluted water effects the water cycle. The resource includes activities for the students to complete, for example students describe the journey of a water molecule from a river high in the mountains, through the atmosphere and eventually back to the starting point. The resource also includes an experiment that students could complete to investigating the effect of pollution (acid rain) on seed germination.

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 lesson begins with a ‘graph description’ activity and opportunity for students to make scientific predictions. Included in the first couple of slides are links to useful video resources for the topic. There is then an option of two different practical investigations. The first invites students to design an experiment testing how the gradient of a ramp effects the speed of the car, whilst the second asks how the height you drop the ball from effect the height of the bounce.
