# 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.
#### 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](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.
