Frottage: Discovering Hidden Patterns
Exploring the technique of frottage to discover and capture hidden patterns and textures from various surfaces in the school environment.
Key Questions
- Predict how the underlying surface will dictate the final image created through frottage.
- Analyze the effects of layering different textures on top of each other using frottage.
- Explain how found textures can be integrated to build a larger, cohesive composition.
National Curriculum Attainment Targets
About This Topic
The study of magnetic poles and the Earth connects the small-scale classroom experiments with the large-scale reality of our planet. Year 3 students learn that every magnet has two poles and that the Earth itself acts like a giant bar magnet. This topic is essential for understanding navigation and the history of exploration, fulfilling the curriculum goal of describing magnets as having two poles.
Students explore why a suspended magnet always aligns itself in a North-South direction, leading to the discovery of the compass. This topic provides a brilliant opportunity to link science with geography and history. This topic comes alive when students can physically model the patterns of the Earth's magnetic field using their own handmade compasses.
Active Learning Ideas
Inquiry Circle: Making a Compass
Students magnetise a needle by stroking it with a magnet, then float it on a cork in water. They compare the direction their needle points with their classmates' needles to find 'North'.
Role Play: The Human Compass
One student acts as the 'Earth' with a giant magnet. Others act as 'Compasses' holding bar magnets, moving around the 'Earth' and showing how their magnet poles react to the Earth's position.
Think-Pair-Share: Lost at Sea
Students are given a scenario where they are lost in a forest or at sea. They must discuss in pairs how a magnet and a piece of string could help them find their way home.
Watch Out for These Misconceptions
Common MisconceptionIf you break a magnet in half, you get a separate North pole and South pole.
What to Teach Instead
Every piece of a magnet, no matter how small, always has both a North and a South pole. If you snap a magnet, you simply have two smaller magnets. Modelling this with 'magnetic tiles' or diagrams helps students grasp this concept.
Common MisconceptionMagnets point to the North Pole because it is cold there.
What to Teach Instead
The North Pole of a magnet is attracted to the Earth's magnetic North, which is a result of the Earth's iron core, not the weather. Using a globe and a bar magnet helps students visualise the internal 'giant magnet' of the Earth.
