The Nervous System Communicates with Muscles through Electrical Waves
Electrical impulses from the brain to the muscles can be observed, measured, and recorded as waves to show that there is a relationship between the circulatory, respiratory, muscular, and nervous systems of the human body.
Sample micro:bit body electrical data graph
Project Goal
Give students real world experience with coding, collecting data, analyzing data, and reporting results using MakeCode’s block programming and a micro:bit with its sensors.
Prior Knowledge
Students need to have a basic knowledge of how to code using block style programming (micro:bit using the Windows 10 MakeCode app) and download a program to a @boardname@.
Student Outcomes
Students will:
- Create experiments to collect data using @boardname@s and measure voltage in the human body.
- Setup different experiments to observe the bodies electrical effect.
- Code the @boardname@s to collect data remotely over the @boardname@ radios.
- Analyze the data collected.
- Report on the findings of the experiments.
Materials Needed
- 2 @boardname@s with batteries connected
- A longer USB microbit cable
- Spreadsheet for data analysis
- 2 long (36-48” or 100-130 cm) thin wires for electrical body sensors (wire from an old network cable works quite well).
- Painters tape to tape the wires to the skin on the body.
