Lesson Objectives Objective: To learn the basic structure of waves, the associated equations and terminology Lesson Outcomes Core: Define the terms frequency, period, amplitude and wavelength of a wave. Challenge: Explain what is meant by phase and phase difference. Aspire: Use the equation c= fL in calculations

Objective: To learn why circular motion is an accelerated motion and needs a centripetal force. Lesson Outcomes Core: Recall that circular motion is a system that is always accelerating Challenge: Understand that circular motion requires a force that acts towards the centre of motion Aspire: Analyse different areas systems to show the relationship between the different components of the circular motion equation.

Lesson Objective To learn about forces, the work that they do and how to measure it. Lesson Outcomes Core level 4: State that energy is measured in joules (J). Calculate the work done by a force. Measure the work done by a force experimentally. Challenge level 6: Describe the action of frictional forces on objects and the associated heating effect. Use the equation for work done to calculate distances or size of forces. Use repeat values to measure the work done by a force experimentally. Aspire Level 8: Use the principle of conservation of energy and forces to explain why objects become heated by frictional forces. Apply the equation for work done in a wide range of contexts. Evaluate in detail an experiment to measure work done, explaining why there is variation in the measurements.
