Pacing: 3 weeks

Stage 1 Desired Results

Established Goals:

• Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration (HS-PS2-1).

Transfer

Students will be able to independently use their learning to….

Meaning

Understandings

Students will understand…

• Newton’s second law accurately predicts changes in the motion of macroscopic objects (DCI - PS2.A).

Essential Questions

Students will keep considering…

• How can tools, technologies, and/or models be analyzed in order to make valid and reliable scientific claims or determine an optimal design solution? (SEP #4)
• How can empirical evidence be used to differentiate between cause and correlation and make claims about specific causes and effects? (CCC-Cause and Effect).
