KS3 Science Unit – 3
Topic: Forces, Magnets, Solar system & Gravity
Activity: Lesson 9 - Magnetism
NC Refs:
Sets:1 lesson for top 2 sets 2 lessons for set 3/4
Yearly objectives:
Range & Content: recognise that magnetic forces act on magnetic materials, recognise magnetism as a force at a distance
HSW describe patterns and trends in results and link these to conclusions,use a model to describe a magnetic field
Outcomes:
All: Describe what happens when a magnetic material approaches a magnet using appropriate scientific terminology, Name three strongly magnetic metals
Most: Describe the shape of a magnetic field around a bar magnet
Some: Explain the difference between a magnet and a magnetic object, Explain what is meant by a ‘magnetic field’
Suggested Activities (including specific refs to HSW):
Starter:
List 3 everyday objects that have magnet in them
9.4Activity 1 Navigation with magnets – Before the invention of GPS, how would ships at sea find their way? Students use bar magnets on string as basic compasses. Ask students to explain observations to provide a basis for reviewing magnet keywords. OR pots of materials can be used to ask pupils if the contents will be magnetic or not.
Main:
• 9.4Activity 2 Magnetic fields – Students remove iron filings from sand as a reminder of the magnetic nature of iron. This also demonstrates part of the magnetic field pattern (see PowerPoint 1) around a bar magnet. Students also try other metals to allow observation that only certain metals are magnetic.
• 9.4Activity 3 Field lines – Introduce idea of field lines by using an electric fan. Paper, on a string, is introduced to the invisible air stream. The movement of the paper is analogous to the force felt by magnetic materials when they are placed in a magnetic field.
Teacher explanation that diagrams can be drawn of the invisible field by using arrows to show the direction of force felt. Students make a diagram of field lines around a bar magnet using small compasses. Confirm pattern using textbook 9.4, p. 109 and on PowerPoint 2.
Plenary:
9.4Activity 4 Permanent vs. temporary magnets – Students use bar magnet to pick up iron nails and steel pins. Students observe difference in behaviour. Link to the difference between permanent and temporary magnets (see textbook 9.4, p. 108).

KS3 Science Unit – 3
Topic: Forces, Magnets, Solar system & Gravity
Activity: Lesson 3 – Gravity and Weight
Yearly objectives:
Range & Content: recognise that there are contact forces and forces that act at a distance
HSW plan an appropriate approach to answer a scientific question making relevant observations, describe patterns and trends in results and link these to conclusions
Outcomes: All: recognise weight is a force measured in N and mass is measured in kg
Most: explain floating and sinking in terms of balanced and unbalanced forces
Some: calculate weight, mass or gravity from data
Suggested Activities (including specific refs to HSW):
Starter:
11.4 Activity 1 Guess the weight of the chocolate bar – Students guess the weight of chocolate bars and establish the difference between mass and weight.
11.4 Activity 2 Weight and mass – A card sort activity which distinguishes mass units from weight units.
Main:
• 11.4Activity 3 What is weight and how can we calculate it? – A demonstration that links weight with gravity and introduces students to the equation for calculating weight.
• 11.4Video Walking on the Moon
• 11.4 Vi.deo Dropping things on the Moon
Two video clips that introduce the idea that weight can change due to gravity. Students calculate the weight of various objects on the Moon.
11.4 Activity 4 Weight in different liquids – Students investigate the effect of different liquids on the weight of an iron block.
