Properties of Matter

Here, students can learn more about how the microscopic behaviour of particles gives rise to macroscopic behaviour; they can...

Teaching Guidance 16-19

Class practical: Students observe brittle fracture during compression of a Crunchie bar, and take measurements to calculate...

Practical Activity 14-16

Class practical: Students make their own springs and use them for investigations involving simple graph construction.

Practical Activity 14-16

Class practical: Though we might claim to know, intuitively, the difference between a large force and small force, we resort...

Practical Activity 14-16

Class practical: The behaviour of springs provides a topic through which students can learn about simple relationships between...

Practical Activity 14-16

Demonstration: The behaviour of a metal when it is subject to a stretching force reveals clues about the forces between its...

Practical Activity 14-16

Demonstration: With a little ingenuity, even a small change in length of a wire becomes measurable.

Practical Activity 14-16

Class practical: To look at a material that does not obey Hooke’s law.

Practical Activity 14-16

Demonstration: By stretching confectionery laces, students learn that extension is not always proportional to load. They also...

Practical Activity 14-16

Demonstration

Practical Activity 14-16

Class practical: As with a spring, force is required to compress or to expand a gas.

Practical Activity 14-16

Demonstration: This experiment is quite elaborate, but it yields quantitative results. A beam balance weighs the pressure.
