 This lesson introduces the student to using the @boardname@ to take measurements and report the results. A few brief experiments are presented and data collected from the experiments is graphed in the MakeCode editor. The data is then available to download to a spreadsheet program for further analysis.

 ## micro:bit setup and coding concepts
 
-This document describes different methods using micro:bits to collect and record data for science experiments. There are several ways to collect data from an experiment. The simplest is having the data display on the LED screen and manually record the data on a paper. Data can also be collected using the Window’s 10 MakeCode app. The third way is using 2 micro:bits with one observing the data and then radioing the results to a second micro:bit so it can allow the remote collection of data.

 Patterns occur everywhere in nature. Certain characteristics in a populations are called traits. Surveys are used to record and help to understand these traits. In this lesson, the @boardname@ is used as a survey tool to count traits. The @boardname@ saves the counts and reports them on the display when asked.

 Not only does water flow across the ground and into soil, 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. This project uses electricity to measure how dry soil has become because of evaporation and transpiration.

 ## Background
 
 This project will use 2 pins on the @boardname@ to measure the voltage between the **3V** pin and the pin **0** as the current travels through the soil. Wires or alligator clips are used to connect to the @boardname@. In the soil nails or larger wires are used as probes in the soil. The nutrients along with the moisture in the soil will allow an electrical current to travel through the soil. The more moisture in the soil the greater the voltage that is measured. Wet soil should have a reading around `1000` on a scale of 0 - 1024. Dry soil will give a reading of around `250`.

 This project will start with one @boardname@ and program it to use the @boardname@’s temperature sensor to collect and display the current temperature in Celsius on the @boardname@’s LED display. The data collected can be recorded manually on a paper with a pencil.
