DIMENSION 3: CORE IDEAS IN FOUR DISCIPLINARY AREAS
PS 1: Matter and its interactions
PS 2: Motion and stability: Forces and interactions
PS 3: Energy
PS 4: Waves and their applications in technologies for information transfer
LS 1: From molecules to organisms: Structures and processes
LS 2: Ecosystems: Interactions, energy, and dynamics
LS 3: Heredity: Inheritance and variation of traits
LS 4: Biological Evolution: Unity and diversity
Earth and Space Sciences
ESS 1: Earth's place in the universe
ESS 2: Earth's systems
ESS 3: Earth and human activity
Engineering, Technology, and the Applications of Science
ETS 1: Engineering design
ETS 2: Links among engineering, technology, science, and society
The framework includes core ideas for the physical sciences, life sciences, and earth and space sciences
because these are the disciplines typically included in science education in K-12 schools. Engineering
and technology are featured alongside these disciplines for two critical reasons: to reflect the importance
of understanding the human-built world and to recognize the value of better integrating the teaching and
learning of science, engineering, and technology. The focus on a limited number of core ideas in science and engineering is designed to allow sufficient time for teachers and students to explore each idea in depth and thus with understanding.
The full report provides detailed descriptions of each core idea, as well as descriptions of what aspects
of each idea should be learned by the end of grades 2, 5, 8 and 12. Establishing limits for what is to be
learned about each core idea for each grade band clarifies the most important ideas that students should
Short Introduction to Dimension 3 Classroom teacher Paul Anderson gives a short video overview of the Disciplinary Core Ideas found in these four domains.
- Physical Sciene,
- Life Science,
- Earth/Space Science
- Engineering, Technology, and the Applications of Science
