Year 3 had fun this week with chocolate rocks!

We used flake bars to represent sedimentary rocks as they have lots of layers.

We pretended we were the Earth and put lots of pressure on the chocolate and observed what happened.

Our pressure and heat changed the shape of the flake bar rocks and made them much smoother.

This is how metamorphic rocks are made deep underground.

We had lots of fun in this lesson but weren’t allowed to eat the chocolate!
