Rock, rattle and roll

Please view our latest Earthlearningidea, 'Rock, rattle and roll; investigating the resistance of rocks by shaking in a plastic container'. Ask your pupils why they think some areas are hilly and others are low lying. Such differences in relief are often caused by the relative resistance to erosion of the rocks; the more resistant rocks usually form higher areas. You can use your local rocks for this activity and then rank them in order of resistance to erosion. A video demonstration can be seen in the post below this.
