Rock, rattle and roll - video demonstration

This video demonstrates our latest Earthlearningidea; click here to view the activity, 'Rock, rattle and roll'. We have also published the video on the website. As you can see from the video, shaking the granite has produced very little dust, the slate a bit more, but shaking the sandstone has made a lot of sand. Granite is the most resistant rock of the three and the sandstone is the least resistant. Children like this activity very much; teachers less so as it is very noisy! Do try it out.
