Description
Designed with middle school students in mind, this activity simplifies NGSS MS-PS4-3 to essential understandings. After this lesson, students will be able to:
- differentiate between the basics of analog and digital signals
- compare the advantages and disadvantages (including reliability) of each
First, students READ the 2-page article. The reading is clear, straightforward, and written for a middle school audience. Topics include:
- Basics of analog and digital signals
- Devices that use each type of signal
- Advantages and disadvantages of each
Second, students ANSWER text-dependent and analysis questions based on the text.
Third, students GRAPH data points for an analog wave and data points for a digital wave. (The Google version of the activity does NOT include this graphing piece. this is only in the print version.) The graphing is very simple, designed not to be a challenging graphing activity but rather to highlight how the two signals graphs are different. A few analysis questions follow the graphs to bring students' attention to the major characteristics of each wave type.
Both PRINT and GOOGLE versions are included!
