Here are a few options:
- Use it as a presentation tool.
- Use interactive group software (taking turns followed by group discussion).
- Use it as a learning station (for resource or for reward).
- Use it for teacher productivity.
If you have a school library or your students all have access to a home computer and the internet then you can do webquests and scavenger hunts. Both use the internet to do an activity that draws information from the web. A webquest is more involved and is based off of a culminating activity, uses higher order thinking and is very structured. A scavenger hunt is knowledge based, doesn't require higher order thinking and is not structured.
By clicking on sites like http://faculty.usiouxfalls.edu/arpeterson/scavenger_hunts.htm for scavenger hunts, and http://www.bestwebquests.com/ for webquests you can get an idea as to what they look like and how they function as classroom/homework activities.
Trust me, they are fun and students like to do them, so give them a whirl and see what happens. Just make sure they compliment your lesson(s) and you teach students how to do them before assigning them.
Enjoy surfing and hunting on the web!
