Alternative Conceptions
When doing the experiments about sedimentary and metamorphic rock, we don’t want students to build misconceptions. Make sure the kids know whats up!
Sedimentary rocks are made in a short period of time?
NO
They are made over thousands even millions of years!
_____________________________________________________________
Rocks are made out of play dough and there is only one way sedimentary and metamorphic rocks can look?
NO
Show them real world pictures, let them know that its the process not the appearance that makes the rocks metamorphic or sedimentary!
_____________________________________________________________
It’s just a colourful rainbow swirl?
NO
The experiment is a representation! Beyond the Explore phase, emphasise this!
