Current and Resistance in an Electrical Circuit The Relationship Explained KS3
What happens to the current when the resistance in an electrical circuit increases? This fully resourced lesson comes with a PowerPoint which uses animations to demonstrate current as a flow of electrons, metal ions as the cause of resistance and conductors having high and low resistance, then guides the student through planning an investigation to discover what happens to the current when the resistance is increased. If the apparatus is not available for a lab, a set of results is provided for students to use to draw a conclusion.
What’s Covered
Resistance is the result of electrons colliding with the metal ions in a conductor.
Resistance increases with the number of metal ions such as in a longer wire.
Plan experiment to investigate the relationship between resistance and current by adding lamps to a circuit and predict the outcome.
Draw up a results table.
Draw a bar graph of the results of the experiment.
Draw a conclusion

Current Electricity - Comparing Lamps in Series Circuits and Parallel Circuits KS3
Pupils learn that, while a parallel circuit has branches, a series circuit does not. By experiment, they will learn that all the lamps in a series circuit are equally bright as indeed they are in a parallel circuit but that identical lamps are brighter when connected in parallel than in series. Lastly, they will show experimentally that lamps in parallel remain on when one is removed but go out when one is removed from a series circuit.
Objective
To know that as lamps are added in a series circuit the lamps become dimmer.
To know that as identical lamps are added in a parallel circuit the brightness of the lamps does not change.
To know that if the lamps in a series circuit are identical, all the lamps are of equal brightness.
To know that if a lamp is removed or breaks in a series circuit, the others will go out.
To know that if a lamp is removed or breaks in a parallel circuit, the others will stay on.

Current Electricity - Current Voltage and Resistance Explained KS3
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.
Objective
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 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.

Current Electricity KS3 - The Complete Module
This one-stop-shop for current electricity at KS3 takes pupils from understanding the terms current, voltage and resistance and the relationship between them, through current and voltage in series and parallel circuits, the resistance of conductors and insulators and how this is used to create components and finishes with Ohms Law.
A free bonus package of a board game, card sort and smart board quiz are included.
The module is divided into 11 fully-resourced, differentiated and engaging topics with the 11 animated PowerPoints and 147 assorted printables making even the more difficult concepts easy to understand. In ten of the topics, after explaining the concept, the PowerPoint takes pupils through conducting and, where appropriate, designing an experiment with results tables. Pupils then explain their results using the theory they were taught at the start. Each PowerPoint ends with an animated class exit ticket quiz giving instant feedback on learning to both teacher and pupil.
In the 39 worksheets/homeworks emphasis is placed on assessment for learning as each module comes with a detailed answer/mark scheme PowerPoint which make self-assessment and peer assessment easy. Each topic comes with a checklist for pupils to assess their progress on completion of the topic.
Each topic comes with a one-page flow-chart lesson plan showing where logical choices between resources can be made enabling the teacher to totally bespoke lessons according to pupil ability, time available for the topic and focus of departmental/school policy. Resources not used in the lesson can be additional homework or used for pre-examination revision. Many activities place an emphasis on literacy and oracy. These are identified on the flow-charts.

KS3 Forces Enquiry/Investigation
The A to Z of an enquiry. This is a fully differentiated and resourced enquiry/investigation into how the surface affects the amount of friction. It is suitable for UK levels 3 to 5 and some elements will start more able pupils thinking about some aspects of level 6 work. It consists of a 27 - slide slideshow and systematically takes the pupils through the stages of planning, developing and reflecting. The whole slideshow contains enough material for 3 to 4, one hour lessons depending on ability. The whole slideshow need not be covered and has been designed so that it is easy to select any sections that are required. It has also been designed so that there are challenging questions for more able pupils but clicking to the next slide provides support for those who need it. Many of the slides are animated.
The resource has been designed to be sufficiently versatile so as to be suitable as not only as an introduction to enquiry/investigation at secondary level but also for those pupils starting upon the transition from level 5 to level 6. It is full of tips on how to tackle the various parts of an enquiry which pupils will find beneficial for those enquiries they tackle in the future and for coping with enquiry-type questions in examinations.
The lessons are easy to follow, enjoyable and easy to teach.
Apparatus needed per group is a newtonmeter and a 1Kg mass. I suggest you have an idea of the 5 surfaces to be used in advance and have a selection of different size newtonmeters available. I use the lab floor, the bench, the carpet in the corridor, a wooden dissection board and a Perspex safety screen. Groups of 3 or 4 are ideal.
Content
Definitions of independent, dependent and control variable, fair test and reliability.
The problem posed is “Does surface affect the amount of friction”.
Planning the enquiry with a worksheet to accompany which includes peer assessment and pupil response to assessment.
Identification of variables
Writing a prediction
Writing success criteria
Designing a table
What is an anomalous result and how to recognise it.
Improvements
Selection of the correct type of graph
How to draw the perfect bar graph (animated)
Reliability and bias
Reflecting on success criteria and learning strategies.
I hope your classes enjoy this and do as well as mine.
