# Overview
|
||
|
||
## Science Concept
|
||
|
||
### Soil, Moisture, Ecosystems, Electricity, and Analog vs Digital
|
||
|
||
Water also moves through the living organisms. Plants soak up large amounts of water through their roots. The water then moves up the plant and evaporates from the leaves in a process called transpiration. Another name for transpiration is evapotranspiration. The process of transpiration, like evaporation, returns water back into the atmosphere ([ck12.org - Processes of the Water Cycle](https://www.ck12.org/book/CK-12-Earth-Science-Concepts-For-Middle-School/section/6.3/)). This project uses electricity to measure how dry soil has become because of evaporation and transpiration.

||
## 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 micro:bit.
|
||
|
||
## Student Outcomes
|
||
|
||
Students will:
|
||
|
||
* create experiments to collect data using microbits and reading the voltage on pin(0).
|
||
* setup different experiments to observe the moisture in soil.
|
||
* analyze the data collected.
|
||
* report on the experiment and the data collected.
|
||
|
||
## Materials Needed
|
||
|
||
* 1 @boardname@ with batteries connected
|
||
* Wires to make or connect to soil probes
|
||
* Spreadsheet for data analysis
|
||
* Word processor for reporting results
