Pupil outcome: I can describe how to make a magnet using an electric current. Key learning points: - When there is an electric current in a wire, there is a magnetic field around the wire. - When there is an electric current in a coil of...

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...

There’s a common movie trope of an actor wiping their fingerprints off a gun. It seems like a simple wipe with a cloth eliminates any trace of a criminal’s guilt, but that isn’t actually the case! Scientists have developed a method that...
