Above is a link to a lesson plan I created revolving around the use of modeling and technology. The technology uses are stop watches and video recorders. The main technology focus is the use of the video recorders where students will use them to document their work. Students will create models during the activity which will represent the data collected from their experiments of dropping bouncy balls and calculating time between two bounces and the max height in between those two bounces. If stop watches are not available then you can measure the distance between the two bounces instead.
