Pure substances and mixtures, the properties that separate them, and the first laboratory techniques.
These are the statements the Science Year 7 syllabus makes about Chemical World. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.

Year 7 Assessment Task Shape is 50 marks in 75 minutes. Questions on Chemical World are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Science Year 7 uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Chemical World is module 2 of 4 in Science Year 7. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Science Year 7 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
