Very cool search engine. You can ask for upper elem to college results. Divides the results into websites, videos and images and if you create an account you can save the items you "pin". If you create a class you can see where your students have been searching. There are even quizzes over material searched.
make sure it works on student computers, uses flash
You could have a worksheet for the student's to fill out as they read answering the online questions.
