Year 9
Density
Use the density equation, determine volume for regular and irregular objects, and apply density experimentally to solids, liquids, and gases.
Part of Year 9 Physics Foundations.
Topic Overview
What students will cover
This topic is highly practical. You need repeated practice in choosing the right method for the material in front of you, then linking your measurements to the density equation.
Keep the distinction between regular objects, irregular objects, liquids, and gases clear as you work.
