Engineering Interact is a wonderful series of sites created by the University of Cambridge. There are several sites on different science topics. Each topic has its own little game, or story mystery that must be played through and solved, complete with interactive puzzles and information. The students are enthralled when they are taking part, and in some ways the activities are very difficult because if you do not read the directions carefully it is impossible to complete the tasks, making the click and jump through crowd unable to progress. Today we played Ocean Oydessy which is an underwater adventure about sound. The Grade 4 class seemed to have a great time, and because it was sound based we did have to wear ear phones so everyone could hear some of their own clues.
