P3.2.4 – circular motion Title: Analysing circular motion Text book Collins further 158-159 Specification c) The centripetal needed to make an object perform circular motion increases as: the mass of the object increases the of the object increases the radius of the circle decreases. Objective: To see how the centripetal on an object changes when we change 3 variables. HSW: AF2 – Understanding the applications and implications of science Outcomes: ALL use a simulator to describe circlar motion MOST change Mass; Speed; and the distance from the centre of the circle – the Radius and record results. SOME write conclusions based on the simulation Starter Review circular motion Main Activities Use the worksheet and the simulator: to see how changing speed, mass and radius effects centripetal force Plenary – Discuss the conclusions made Additional Resources and web links – Computer room Differentiation: Outcome and assistances in practical V – PowerPoint on screen and practical simulation A – discussion K – Practical L – discussion R/W – excel Key skills: observing, recording, analysing, PLTS:. Team workers – Work collaboratively with others. ECM: stay safe – how to identify and minimize risk Assessment – Teacher assessment in plenary Q & A assessment throughout HW: homework doddle – Safety: Keywords Force, Centripetal force, orbit, speed, velocity Activity and Resources.

P3.2.1 – centre of mass Title: Investigating pendulums Text book Collins further 160-161 Specification P3.2.1 Centre of mass d) For a simple pendulum: T = 1/f e) The time period depends on the length of a pendulum. Objective: Be able to carry out a practical to investigate pendulums. HSW: AF2 – Understanding the applications and implications of science Outcomes: All Must measure time period and frequency for a pendulum oscillation. Most Should carry out a practical safely and make a conclusion. Some Could explain how the period of a pendulum changes with the length of the pendulum. Starter What did you learn yesterday?

P3.3.1 – The motor effect Title: Electromagnets Text book Collins further pages 172-173 Specification P3.3 Keeping things moving P3.3.1 The motor effect a) When a current flows through a wire a magnetic field is produced around the wire. b) The motor effect and its use. c) The size of the force can be increased by: increasing the strength of the magnetic field increasing the size of the current. d) The conductor will not experience a force if it is parallel to the magnetic field. e) The direction of the force is reversed if either the direction of the current or the direction of the magnetic field is reversed. Objective: Be able to describe how to change the strength of an electromagnet. HSW: AF2 – Understanding the applications and implications of science Outcomes: All Must Describe how to make an electromagnet Most Should Describe how to make an electromagnet stronger Some could Describe the motor effect Starter What can you remember from KS3? Make an electromagnet? Make it stronger. Write a description of how to make an electromagnet and how to make it stronger.
