The Core Knowledge Science (CKSci) program includes the comprehensive elementary science curriculum, plus additional resources for teachers and students in Kindergarten through grade 5.
The curriculum, which follows the Core Knowledge approach, provides students with a firm basis in the factual knowledge of the sciences and engineering design specified in the Core Knowledge Science Sequence. Additionally, this program has been informed by many positive aspects of the Next Generation Science Standards (NGSS).
CKSci Curriculum Components
For each grade level, you’ll find a range of titles to cover during the school year with each year building upon the knowledge learned in the previous year. The Core Knowledge Science program includes what you’ll need to begin implementing the curriculum at your school or at home.
- Student Readers: engagingly written to bring the wonders of the world right into your classroom, also available as e-books
- Teacher Guides: with detailed lesson plans and activity page masters, including student investigation guides and assessments and notes for NGSS Performance Expectations
- Online Resources Guides: with links to resources that support learning and engagement with the core ideas in science and engineering

Featured Title: Electricity and Magnetism
In this Grade 2 Core Knowledge Science unit, students will trace the path of electricity from the power plant, through their home, and to wall sockets.
Integrating Science Curriculum With Additional Subjects
CKSci follows our approach to knowledge-based schooling. It allows students to build and deepen their knowledge grade by grade and to make cross-curricular connections across subjects.
CKSci and Language Arts
Core Knowledge Language Arts (CKLA) offers early exposure to many of the same core ideas as CKSci, supporting a student’s learning progression toward an ever more complex understanding of science.
CKLA lays a foundation of knowledge and literacy about a topic before students are expected to investigate phenomena through the lens of scientific practices and crosscutting concepts. It covers many of the same topics as CKSci, like light, sound, habitats, and astronomy, specifically for the purpose of building background knowledge and literacy with informational texts.
