Ask testable questions, make evidence-based predictions, and identify cause-and-effect relationships from observations and science stories.

Compare natural water bodies, distinguish freshwater from saltwater, and practice protecting and conserving water.

Construct physical models and engineering prototypes to represent natural phenomena, solve problems, and identify model strengths and limitations.

Understand that complex objects are systems of interacting parts that can be taken apart and rebuilt.
