In case you were wondering, here’s how to make the three types of rock:

To make an igneous rock using Starbursts, you stack three Starbursts and microwave them until they resemble bubbling lava! As the children found out, this smells delightful!

To make a metamorphic rock, you squish together three Starbursts until they melt in your hands and roll into a rock shape.

To make a sedimentary rock, you stack three Starbursts and squish using all your might!

Another tempting task for Year 3, but no eating in the Sky Lab please!
