Lesson 6 – Nitinol and carbon nanotubes explained
In these lessons students will investigate:
- The properties of Nitinol alloy.
- How electric current can be used to change the shape of memory alloys.
- The properties and structure of Carbon Nanotubes.
- Memory shape alloys have the potential to be used in a variety of engineering applications.
- Carbon Nanotubes can be used to produce very strong and useful structures.

Review the students understanding of the key points in lesson 5.
Investigation – Students explore how passing a current through a memory shape alloy can heat it to realign to its heated state and the potential applications of this property. Teacher demonstration.
Investigation – Teacher introduces and discusses the YouTube Heatmobile and YouTube - WTF Paperclip Nitinol. Resources
Investigation – Students view PowerPoint 6.1 Carbon Nanotubes.pptx. Resources
Reflection – Students view YouTube – Nanotechnology Today and discuss the ideas presented. Resources
Discussion – Students divide into breakout groups and given a range of short articles on carbon Nanotubes to read and discuss. Their findings are shared on a Padlet page. Resources
Movie: Using Padlet (3:46mins)
Students work on developing a media file of applications of Nanoscience encountered in reports of local media items for the final week. Media file is shared on NVSES network.
