Magnetic forces can act at a distance when some materials are placed between the magnet and the magnetic material
Scientists can carry out investigations to test which materials allow magnetic force to pass through
Sometimes the results of an investigation are different to what was expected or predicted

Magnets can exert a force through paper, but not wood, a table, or other thick materials.

Explicit teaching and investigation will clarify that magnetic force can act through a range of materials.

Magnetic force - Magnetic force is the force caused by a magnet.
Block - To block something is to stop it from moving or having an effect.
Non-contact force - A non-contact force is a force which occurs when objects are not touching each other.
Material - A material is the thing that objects are made from such as wood.
Predict - To predict is to say what you think will happen.
