Year 3 – CBOL Session 10: Forces (Magnets)

This fully resourced outdoor science session explores both contact and non-contact forces, focusing on magnetism and strength through structured team challenges and fair testing investigations.

🧲 Core Learning:

Students learn:

• A magnet produces an invisible force
• The force is strongest at the poles
• Opposite poles attract
• Like poles repel
• Only certain metals (iron/steel, nickel, cobalt) are magnetic
• The Earth has a magnetic field
• A compass works because of Earth’s iron core
• Strength can be measured through comparative testing

🚀 What’s Included:

✔ Detailed Teacher Guide with structured session script
✔ Laminated Magnet Behaviour Cards (Attract, Repel, North, South, Pole, Magnet)
✔ Laminated Magnetic Materials Cards (Magnetic, Non-magnetic, Iron, Metal, Field, Strength)
✔ Iron Detective Sorting Challenge Plan
✔ Magnetic Poles Command Game Instructions
✔ Compass Investigation Worksheet
✔ Magnet Strength Fair Test Investigation Sheet
✔ Equipment & Setup Checklist

🔬 Investigation 1: Compass & Direction

Enquiry Question:
How can a magnetic compass help us find North, East, South and West?

Students:

• Hold the compass flat
• Align the needle to North
• Rotate 90° clockwise to find East, South and West
• Record landmarks
• Analyse directional accuracy

They apply:

• Control variables
• Accurate observation
• Real-world navigation skills

🔬 Investigation 2: Magnet Strength (Comparative Test)

Enquiry Question:
How does the type of magnet affect its strength?

Students:

• Test different magnets (disc, bar, horseshoe, ring)
• Add identical paperclips one at a time
• Record how many each magnet can hold
• Compare results
• Draw evidence-based conclusions

Independent Variable: Type of magnet
Dependent Variable: Number of paperclips held
Control Variables: Same objects, same method, same surface

This lesson builds:

• Scientific vocabulary retention
• Enquiry structure (Prediction → Method → Record → Conclusion)
• Teamwork development
• Logical reasoning
• Data comparison skills

And most importantly…

Children leave understanding that not all forces require contact.

Some forces work invisibly.

Description

This is the lesson where children realise…

Magnets don’t need to touch.

In Session 10, your Year 3 pupils act out attraction and repulsion — physically linking arms as North and South, pushing apart as North and North.

They don’t just memorise “attract” and “repel.”

They become the poles.

Then comes the Iron Detective challenge.

Because here’s the misconception:

“All metals are magnetic.”

Nope.

Aluminium? No.
Copper coin? No.
Steel paperclip? Yes.

They test.
They predict.
They correct their thinking.

Then it gets even better.

Each child uses a real compass.

They discover that the needle always finds North — not because it’s magic, but because of the Earth’s magnetic field.

And finally…

They investigate strength.

Which magnet holds the most paperclips?
Does size matter?
Is a horseshoe stronger than a disc?

They measure.
They compare.
They conclude.

This isn’t just a magnet lesson.

It’s vocabulary mastery.
Fair testing.
Real scientific reasoning.

Structured.
Active.
Curriculum aligned.

📥 Ready to buy. Ready to teach. Ready to unlock invisible forces.
