PowerPoint that covers power and the cost of electricity for a KS3 level class. The starter revisits efficiency and energy stores from previous lessons to enhance memory recall. The power equation (power = energy transferred / time) is covered with an example of how to show working out. Slides include rearranging the equation and unit conversions. The cost equation (cost = power x time x cost per kWh) is also covered. Answers are included.

Describe the difference between mass and weight. Describe the forces acting on an object falling through a fluid. Explain what terminal velocity is and when it is reached.

PowerPoint that covers the following learning objectives: Investigate how light travels through a lens. Describe the difference between a convex lens and a concave lens. Identify the focal point in a light ray diagram of a convex lens. This is made for a KS3 science class. Includes questions, answers, diagrams and link to a virtual simulation.

Learning objective: Describe the magnetic field produced by a current-carrying wire and use the corkscrew rule to determine the direction of the field around it.

PowerPoint that covers generating electricity by combusting fossil fuels. Includes how fossil fuels are formed, what we use them for, how electricity is generated and the advantages and disadvantages. This is made for a KS3 level class. The starter activity revisits efficiency and power from previous lessons to enhance memory recall.

PowerPoint that covers the following learning objectives: Describe and explain what happens when light is refracted. Draw a refraction diagram. Includes diagrams, explanations, questions and answers. If you could spare 5 minutes, please review this resource, to help my online presence grow! :)
