Thanks for positive comments

Thank you for the positive comments Pete and for the ideas for further development of Quake Shake. Using objects of varying shape to investigate stability will lead to yet more fruitful discussion amongst pupils. Hopefully, each activity we publish will generate some good ideas which we intend to add in a 'blog feedback' file to each activity.

Thanks also Dawn for your encouraging comments about Earth Learning Idea. It is great to know we have the support of the Earth Science Teachers' Association.
