Higher:
Is able to conduct a test on different materials to see if they are attracted to magnets
Middle:
Can identify materials that can be attracted to magnets
Lower:
Is able to find out about the history of magnets
Lesson Recap Starter: Think back to the last lesson. What does the word property mean?
Lesson Starter: Watch the clip of the magnets being attracted to one another.
Can children identify some places in the home or in school where magnets are used?
Presentation - Starter Slide.
Run through the presentation on magnets, magnetism and where we may find magnets being used.
Watch the Challenge Film. What objects can children identify and what materials are they made from? Can they guess which object might use a magnet in some way?
Stop the presentation at the relevant slides: Talk Partners; AfLs; Songs.
Take part in the Choral Response Questions activity (see Assessment section) after the Keywords/Rocket Words slide.
Key Concept:
During this unit, each lesson contains a key concept question housed in the '30 Second Challenge' slide. To help children master this content so the knowledge moves from their short term memory to their long term memory, at the beginning of the follow on lesson the question from the previous lesson is revisited.
The questions covered during this unit include:
1. Describe cotton. Describe wood. Describe cotton. Describe metal.
2. What does the word property mean?
3. How can a magnet be used?
4. What metals does material need to contain for a magnet to attract it?
5. What two actions can a magnet create on another material which contains iron?
6. What is the difference between natural and man-made materials?

Magnets in Objects
The lesson assignment video shows several examples of magnets being used.
The children must identify how the magnets are being used.
You can then explain that magnets are found in objects that contain an electric motor, make sounds (speaker) or record sounds.
Encourage them to find objects around the room that might fit that description.
Then get them to complete the Handout.
Magnets in Objects
Objects that contains magnets (optional)
Video
Handout
When all groups have completed their task, a representative from each group will state their predictions and their findings and the similarities of the items that they were able to pick up with the magnet.
Have a group discussion about the results, and why they think there predictions were correct or incorrect.
Quiz
With their talk partners, the children are to go through the quiz at the end of the presentation and answer the questions.
Quiz in presentation
Are children able to recognise material which are made from wood, metal and plastic?
Are children able to identify materials which are magnetic or non-magnetic?
What words are children using to describe the materials and their properties?
Quizzes available in pupil zone.
Unit knowledge organisers and tests available in unit / lesson documents area.
Magnets can pick up...(metal)
Magnets are useful because...
Some materials are more (magnetic) than others, such as...
You can test if a material is magnetised by...
The Science Behind the Science
Magnetism is created by the motion of electrical atoms. When all of the electrons in an element spin in the same direction, they have the potential to become magnetic. They can only become magnetic, however, when they enter the magnetic field of another magnet, so an existing magnet is needed to create a new magnet.
Iron is magnetic, therefore any alloy, such as steel which contains iron, is also magnetic. Other metals which are magnetic are nickel, cobalt, and a few rare earth metals.
Some animals can sense magnetism and use it to navigate around the world.
Fun fact: Farmers feed cows "cow magnets" to collect pieces of scrap metal that the cow may have swallowed by accident.
To identify and name a variety of everyday materials, including wood, plastic, glass, metal, water, and rock.
Planet Earth - Energy sources and sustainability - I am aware of different types of energy around me and can show their importance to everyday life and my survival. SCN 1-04a Forces, electricity and waves - Forces - By exploring the forces exerted by magnets on other magnets and magnetic materials, I can contribute to the design of a game. SCN 1-08a
Forces and Energy: the study of energy, its origin, storage and transfer and the work it can do; the study of forces; the application of scientific understanding through inventions and machines.

Cross Curricular Link for Mathematics: Measurement: Ask pupils to describe the mass/weight [for example, heavy/light, heavier than, lighter than] of the different objects they are exploring.
Grade 2 - Force, Work and Energy
List the magnets of different shapes commonly used in life Observation describes the basic characteristics of common objects, identifying common materials in life, knowing common forces.
