Step 4: Showing off.
If your class have followed an existing Instructable, they will still have pride in their work and want to show off their achievements to the world.
This is a perfect excuse to produce a slideshow on the site.
Take photographs of your students' work, and upload them all into a single slideshow - you and they can share the URL of the project with their friends and family, post it in their blogs or on social networks.
This use is also very suited to the work of younger children, who are less able to take step-by-step photos themselves, and so have to rely on you to take photos of their finished work.
