Description

This action-packed lesson introduces current as a flow of electrons and explains the relationship between current, voltage and resistance using the analogy of a diver using up energy obtained from food and giving off heat as they swim through pipes filled either with water (low resistance) or water and rocks (high resistance). The food as a source of energy is then replaced by the battery, the diver by the electron and the rocks by metal ions. Both scenarios are animated in the PowerPoint. This explanation is then extended to compare the resistance of long, short, thick and thin wires. The practical explores the conditions needed for current to flow in a circuit.

Objectives

To know that current is a flow of electrons through a conductor when they are given energy or pushed by a voltage from the battery.
To know that and explain how metal ions cause resistance.
To know and explain the comparative resistance of wires according to length and thickness.
To explain why electrons lose more heat passing through a high resistance conductor.
To know the conditions needed for current to flow in a circuit.

With 14 original, enjoyable and engaging pupil resources and two PowerPoints, this pack is designed to be totally bespoked by the teacher to perfectly match pupil ability, time allowed for the topic and departmental focus. Depending on the resources chosen teaching time can take between 50 minutes and two hours. Resources not used in the lesson can be utilized for homework and pre-exam revision/review.

There are 14 differentiated learning outcomes – please see preview.

A clear and concise one-page flow-chart lesson suggested lesson plan is included showing the logical places where choices between resources can be made. Instructions for use are clearly explained on each resource.

Resources include elements of literacy, oracy, self-assessment, peer assessment and teacher assessment which are clearly identified on the flow-chart.

One PowerPoint is richly animated and is the backbone of the lesson. The other is the answer/mark scheme for all assessment material so that self-assessment and peer assessment is extremely easy. Facility is also made for pupils to reflect on their performance.

This pack part of an 11 topic module. Please follow the link below to my shop or the links to other resources in this series.
