# Overview
|
||
|
||
## Science Concept
|
||
|
||
### 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.

||
## Project Goal
|
||
|
||
Give students real world experience with coding, collecting data, analyzing data, and reporting results using [MakeCode’s](https://makecode.com) block programming and a [micro:bit](http://microbit.org) 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.
