# Overview
|
||
|
||
## Science Concept
|
||
|
||
Surveys of different characteristics in a population can be done in several different ways. If it is people responding to a survey it could be done orally, on paper, or electronically to collect the data. If it is done by observation, it could be done with tally marks on a paper. If 2 different characteristics are being observed it is really hard to mentally keep track of 2 counts in a person’s head. It could be done on a @boardname@ using the **A** and **B** buttons as increment counters. The @boardname@ could also be programmed to show the 2 tallys and the total number observed.
|
||
|
||
The strands and standards in 7th grade SEEd 7.5 talk about “... variation and the proportion of traits within a population can change over time…” Observing current traits in a population is a start to looking at changes in a population overtime. Standard 7.5.2 “Analyze and interpret data for patterns...” Possible observations could include: blond vs non blond, male vs female, cars vs trucks, right handed vs left handed, etc.

|
||
## Project Goal
|
||
|
||
Learn coding with math concepts to create a microbit 2 trait counter.
|
||
|
||
## Prior Knowledge
|
||
|
||
Students need to:
|
||
|
||
* Have a basic knowledge of how to code using block style programming (Scratch, Code.org, etc.)
|
||
* Basis knowledge of the MakeCode programming environment.
|
||
* Knowledge of using variables and basic math in coding the microbit.
|
||
* Knowledge file management skills in Windows.
|
||
* How to download a program and copy it to a microbit. Checkout this guide: [Using a Microbit in 5 easy steps](http://microbit.org/guide/quick/).
|
||
|
||
## Student Outcomes
|
||
|
||
Students will:
|
||
|
||
* Create experiments to collect data using a microbit to collect and count 2 types of data.
|
||
* Setup different experiments to observe the gravity effect.
|
||
* Code the microbit using variables, counters, and math to collect and display data.
|
||
* Analyze report on the data collected.
|
||
|
||
## Materials Needed
|
||
|
||
* 1 @boardname@ with battery connected
|
||
* Windows 10 MakeCode app or [MakeCode](@homeurl@) in a browser.
