"Doing science": making home-made edible rocks. And while we're at it, we're learning about the three types of rocks and the rock cycle.
Igneous rocks (volcanic) are formed through the cooling and solidification of magma or lava.

Lollypops cooked up to 310 degrees and cooled to room temperature. |
Sedimentary rocks (layered) are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans. The sediment is compressed over a long period of time before consolidating into solid layers of rock.

Layers of vanilla wafers, butterscotch chips, chocolate chips and nuts. |
Metamorphic rocks (changed) have been changed over time by extreme pressure and heat.
Ready to bake for 20 minutes to make soft cookies.
And then sliced and cooked for another 10 minutes to "morph" into metamorphic cookies.
The best part: eating rocks!
