Measuring and Observing with Science Tools

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

Plan step-by-step descriptive investigations, change one condition at a time, and conduct fair tests safely.

Select and use rulers, pan balances, thermometers, rain gauges, and hand lenses to gather sensory and quantitative data.

Apply safety rules, recognize hazard symbols, follow emergency procedures, and stay safe during outdoor field explorations and weather events.

Record observations with drawings, words, and tallies, organize numbers into charts and bar graphs, and find patterns in scientific data.

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

Construct evidence-based explanations, communicate scientific ideas using science vocabulary, collaborate respectfully, and explore how science helps society.
