Cornerstone’s Cycle 1 Base Kit provides durable science materials designed to pass from class to class, plus consumable supplies for one class of 8 students and 1 tutor using the Classical Conversations Cycle 1 curriculum. This kit forms the foundation for Cycle 1 science activities and supports consistent instruction across your community.
The Base Kit is ideal for hands-on science, community classroom use, and long-term stewardship of resources.
Purchasing Guidance
How many should I order?
We recommend purchasing one Base Kit for each of the first classes doing science simultaneously in your community. Next, purchase as many Class Packs (LINK) as you have additional science classes that will follow afterward.
-
Number of classes starting the day = number of Base Kits
-
Number of additional classes = number of Class Packs
Examples:
A community with 24 students where one class begins science first and two follow later will need one Base Kit and two Class Packs.
A community with 48 students where two classes begin science simultaneously and four follow later will need two Base Kits and four Class Packs.
