Which guide helps a rolling ball reach a marked target?
Analyzing and interpreting data · Related lesson: Kindergarten, Push and Pull Forces
Investigate, model, explain and improve a design.
These projects address previously unmapped NGSS references: 14 elementary, 15 middle-school and 35 high-school expectations. Each includes an idea explanation, evidence or model inputs, a task, reasoning checks and a teacher rubric. Three include interactive models.
Project availability is not evidence that every student has mastered the expectation or that the complete curriculum is covered. Other mapped expectations still require review of full instruction and assessment. State-specific crosswalks remain incomplete.
