Google Inside Search will give you access to a lot of neat features from Google. You can explore different tips and tricks, search stories, learn how Google Search works and follow different blogs etc. My personal favorite though is Google Playground where you can access Google A Day, or find past Google Doodles, view demo slams and you can even get a snapshot of a days worth of Google searches around the world. Hopefully you can find something that pertains to your class if not this site is a neat time filler that has a lot of information.
