This one is tough to categorize. Enter a day of the year, and this site will tell you about important events, births, and deaths that have happened on that day. Try using this one to create a list of important events - covering a variety of subject areas - for an entire week.

tag(s): quiz (88)

In the Classroom

This site would make for a great creative writing project for students in a high school english class. Have students search for their birth date, and find one person on that list that they can focus their paper on. Have students research their historical person, eventually writing a analytical paper about the similarities and differences between their own life and that of their selected person. Teachers can focus more on similarities to make it more difficult and interesting - but it is a great way to get students thinking about comparing and contrasting.

OK, this one's mostly for fun, and we're showing our age. Still, the online version of the famous drawing toy performs much as the original did. Try this one on your students as an example of what high tech was thirty years ago. Just don't try to clear your screen by turning it upside down and shaking it! Operate the game using the arrow keys on your keyboard.

tag(s): drawing (83)

In the Classroom

Have young ones practice left and right by working with a partner at classroom computers, with one partner directing "left" or "right, "up" or "down" while the other operates the keys. Together they can make a drawing! Older students will be amused by the simplicity. See what they can create with just one continuous line.

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 (94)

In the Classroom

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.
