Scope and Sequence
Stardust to Storytellers: Prehistory is designed for learners in grades 2 through 7 and functions as a full-year science survey course. It can be flexible to work for kids in grade levels outside of these. The curriculum covers approximately 32 weeks of instruction at the pace of one lesson per week. No prior science background is required for either the learner or the instructor.

What’s Included: This curriculum includes three components: the Teacher's Guide, the Student Workbook, and the Lab Book. You do not need to use all three. The Teacher's Guide is the only essential piece. The workbook and lab book are included because many families find them useful, but they are entirely optional.

Subject areas covered: astronomy, Earth science, geology, paleontology, evolutionary biology, and early human history.

Recommended grade range: 2 through 6 (adaptable for younger or older learners with guidance from the Tips for Different Learners section).

Seat time: Approximately 2 to 5 hours per week depending on which optional components are included.

Prerequisites: None.

Week-by-WeekThe table below shows the science topics covered in each lesson. This is meant to help you plan ahead, identify areas where your learner already has background knowledge, and see how the curriculum builds over the year.
