Unit / Theme
NGSS Disciplinary Core Idea (DCI)
Performance Expectations (PEs)
Key Concepts
Unit 1: All About Us – Body and Senses
LS1.A: Structure and Function
K-LS1-1
Using senses to explore environment
Use senses to gather information
Unit 2: Living and Non-Living Things
LS1.C: Organization for Matter and Energy Flow in Organisms LS4.C: Adaptation LS1.A: Structure and Function
Living vs. nonliving, basic needs of plants/animals Animal features, where animals live Plant parts, how plants grow
Observing, comparing Construct explanations Making observations, sequencing
Unit 3: Our World – Earth, Sun, and Moon Unit 4: States of Matter
Unit 5: Forces and Motion
K-LS1-1 K-ESS3-1
Science and Engineering Practices (SEPs)
Crosscutting Concepts (CCCs)
Focus Questions
Real-life Connections
Systems and System Models
How do our body parts and senses help us?
Use senses during class activities (e.g., hearing music, smelling flowers, touching textures).
Structure and function Patterns
How do we know something is living or not? Where do camels live? How does a seed grow?
Classify toys, pets, and plants as living or non-living in the classroom. Where do camels live? Plant a seed till it grows.
What do we see in the sky?
Daily drawings of the sky, noticing changes between day and night. What can we build with rocks, wood, etc?
What are solids, liquids, and gases?
Sort objects during nature walk by material type (e.g., rocks, water, air balloons).
How do we make things move? What makes sound?
Rolling balls, pulling wagons, and pushing toy cars in different directions.

Template Notes: • • • •
Performance Expectations (PEs) are taken from Kindergarten-level NGSS, as Pre-K is considered a foundational, exploratory stage that builds readiness. Science and Engineering Practices (SEPs) and Crosscutting Concepts (CCCs) are simplified for early learners but kept consistent with NGSS. Time frames can be adjusted based on the number of school weeks or local curriculum pacing. Each unit includes sample driving questions or hands-on ideas to guide instruction.
