Overview:
The goal of this lesson is to apply NGSS science and engineering practices, disciplinary core idea, and crosscutting concepts to investigating the way in which EV3 sensors work. Students make a claim about how sensors work then must design an investigation to prove they are correct.
SEPs used:
Questioning
Developing models
Planning and carrying out an investigation
Analyzing and interpreting data
Using mathematics
Constructing explanations
Engaging in argument from evidence
Communicating information
DCIs addressed for Middle School grades 6-8:
ps4-1 Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
ps4-2 Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
ps4-3 Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
CCs discussed:
Cause and Effect
System and System Models
Structure and Function
Patterns
