After finding inspiration to learn about crystals in a gem shop, Barbie and her friend visit a natural history museum. A geologist teaches them about the rock cycle and then takes their whole science class on a field trip to find and identify real mineral specimens. As you read the story, you can perform experiments alongside Barbie to learn about geology. Use special tools to excavate three real mineral specimens from a plaster block. Conduct mineral identification tests on them to find out what they are. Then, mount the mineral specimens onto rings you can keep and wear. Learn about the geological science of how minerals form, the rock cycle, and mineral identification tests.
