Observing Movement on Surfaces
Students will investigate how objects move differently on various surfaces, observing how some surfaces make things slow down or stop more easily.
Key Questions
- Compare how objects move on different surfaces and identify patterns in their motion.
- Explain what causes some toys to slide further on wood than on carpet.
- Predict which surface would make a toy car travel the shortest distance.
National Curriculum Attainment Targets
About This Topic
Magnetic attraction and repulsion introduce Year 3 students to the concept of non-contact forces. This topic covers how magnets can pull or push objects without touching them, a concept that often feels like magic to young learners. Under the National Curriculum, students must observe how magnets attract or repel each other and attract some materials but not others.
This unit builds the foundation for understanding fields and forces that act at a distance. Students learn to distinguish between magnetic and non-magnetic materials, discovering that not all metals are attracted to magnets. Students grasp this concept faster through structured discussion and peer explanation as they try to predict which objects will react to the magnet's pull.
Active Learning Ideas
Gallery Walk: Magnetic or Not?
Place various items around the room (coins, clips, foil, plastic). Students move in pairs with a magnet, predicting which are magnetic, testing them, and recording results on a shared class chart.
Simulation Game: The Invisible Maze
Students place a paperclip on top of a piece of card and move a magnet underneath to guide the clip through a drawn maze. This demonstrates how magnetic force acts through materials without direct contact.
Peer Teaching: Attraction vs Repulsion
In pairs, one student acts as the 'North Pole' and the other as the 'South Pole' using bar magnets. They demonstrate and explain to another pair the rules of 'like poles repel' and 'opposite poles attract'.
Watch Out for These Misconceptions
Common MisconceptionAll metals are magnetic.
What to Teach Instead
Only certain metals like iron, nickel, and cobalt are magnetic. Many common metals like copper, aluminium, and gold are not. Hands-on sorting tasks with various metal objects help students see this distinction clearly.
Common MisconceptionBigger magnets are always stronger.
What to Teach Instead
The strength of a magnet depends on its material and how it was made, not just its size. A small neodymium magnet can be much stronger than a large ceramic one. Testing different sized magnets to see how many paperclips they can pick up helps correct this.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.

Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
