The design of this privately developed site shows its age, but users will find abundant content and visuals here. It just takes a little work. The site covers the evolution of technologies ranging from the earliest wax recordings to today's DVDs. Along the way, users can learn about the people and processes that have helped sound and video recording develop.

tag(s): inventors and inventions (99)

Teachers may want to guide their students' use of this site. This site is a little text-heavy, but would be a great way to show the progression of the music industry over the modern era. Share this site on an interactive whiteboard or projector as an introduction to this unit or as review.

Here's one that will tie your brain in knots. Some of these logic puzzles will challenge even advanced high school students, but both solutions and discussion are readily available for those who struggle. There are many different puzzle types, and new content seems to appear regularly. Note, however, that the ad banner space occasionally displays content that some might not deem appropriate for school use.

Teachers will find this one a great source for "extra point stumpers."
