Play dough Landforms
We are going to use play dough to help you
understand how these landforms are made. To do this
you must abide by the rules and produce a piece of
writing afterwards to explain how the landform was
used.
1. Do not throw or mix the play dough
2. Follow instructions first time
3. Do not eat the play dough
Breaking these rules will result in the play dough
being taken away from you and you will just write
instead.
