The 3 types of rocks
and how they are formed
Sedimentary rocks
Igneous rocks
Metamorphic rocks
I remember reading about taking
core samples from cupcakes to show the kids how core samples are
taken from the Earth and studied. I decided it would be fun to
try it on a sandwich with more possible layers than a cake. So
I googled it and came up with
this. Sounded fun! We tried it last night but it
didn't turn out as I had hoped. I think the cakes would work
much better. The sandwich just all squished together and we
couldn't tell each layer apart but it did do the trick and the kids
understand about core samples, etc.
I wanted my sample to look like this
but mine didn't.
