Lesson 3 – Investigation of the effects of particle size
In these lessons students will investigate:
- The bonding model of metals and how this is responsible for the properties of metals at the Macro scale.
- How metal properties can be modified through the preparation of alloys.
- Learn how the bonding model is responsible for properties of metals.
- See how the ideas discussed can be observed and investigated during simple experiments.

Review the students understanding of the key points in lesson 2.
Investigation – Students investigate how the properties of materials can change as we change the particle size. Experiment (3.1) – Burning steel wool when open and packed, Experiment (3.2) – Burning methylated spirits when liquid or in a spray, Experiment (3.3) – Optical properties of raw sugar when crushed.
Investigation – Teacher introduces PowerPoint – Understanding metals.pptx. Resources
Discussion – Students discuss the ideas of different sorts of bonding and properties of metals as seen in the PowerPoint – Understanding metals.pptx.
Collaboration – Students brainstorm by working on the Metal Lotus diagram.docx. Resources
Reflection – Students divide into breakout groups and identify links between the ideas in the video, PowerPoint and the experimental demonstrations and discuss. Resources
Students work on developing a media file of applications of Nanoscience encountered in reports of local media reports. Media file is shared on NVSES network.
