Fun Free Science Lesson Link

This was sent to my email and I found it interesting so I want to share this here:

We would like to bring to your attention a hands-on science lesson that captures students̢۪ attention when they used crystals that disappear when placed in water and reappear when removed from the water. These crystals (actually a hydro-gel) are used to teach the concept of refraction of light and the basic chemistry of crystal growth. The lesson is written for teachers of upper elementary and middle school age students. The activity is posted on a commercial education products website, but the lesson plan is free for use by teachers. To view the lesson visit
