RET Teaching Module 13: mixedSignals -  Analog vs Digital

Overview

In this module, students will expand their knowledge of energy, electrons, circuitry, and waves to explore their connections in the technology. Students will start honing in on familiar topics that have nanoscale connection: electron flow, circuitry, and computers. The lesson will culminate with students building and programming an electrophysiological sensor. They will use a program that displays data collected from the electrophysiological sensor. They will then analyze the data in the output. After students interact with the data, they will then use a program that takes the data produced from the electrophysiological sensorand converts it to a digital and analog signals to complete a given task.At the end, there is an enrichment activity with a brief introduction to nanotechnology. Students will use multiple forms of media to broadly explore topics in nanotechnology. The technology used in the lesson can be used to spark discussion during the nanotechnology enrichment.

After completing this module, student should be able to:

• Assemble and program an electrophysiological sensor
• Collect and analyze data
• Observe how analog signals can be converted to digital signals for functionality purposes
• Claim and support with evidence why digital signals are more reliable than analog signals
• ENRICHMENT: Give examples and explain the importance of several technologies possible because of nanotechnology
