Sensor data collection for class projects

RPi-Logo-Stacked-SCREEN

Collect data with sensors for classroom exploration.

Involving students in the first step of the data collection process promotes engagement and interest.

It’s hard to collect accurate data in the real world. Students must learn to be aware of different variables that impact readings and to harness their critical thinking skills to troubleshoot often.


Raspberry Pi
Raspberry Pi is a small, microcomputer processor with an average cost of $25-$35. This simplistic device can be outfitted with different sensors, including those that measure temperature, moisture, humidity, and so much more.

Without a keyboard or monitor, the Raspberry Pi can be set up in any location in a classroom and take measurements of sensor data at requested intervals.

Once collected, data can be downloaded and used for analysis.

Hawkes is using these devices to set up several experiments to provide a live data feed for free use, and you can too!


Here are 3 ideas for experiments that we have in the works using Raspberry Pi:

1. Bamboo growth
Follow how quickly different bamboo plants are growing and what impacts their growth. You can also check out the cool sensor data PiPlanter is collecting, including soil humidity and ambient light, to create a clever irrigation device!

2. Air quality control
Track carbon monoxide emissions and see how the readings change as distance to humans varies.

3. Temperature
Assess temperature in different locations of the room. Watch out for variables such as air conditioning drafts, sunlight, and proximity to people and computers.

You focus on teaching. Let us provide the data.

The new Discovering Statistics and Data text offers 36 (and counting!) real data sets for free download.

Data Set Obesity

The companion website to the new Discovering Statistics and Data textbook, stat.hawkeslearning.com, supplies updated and relevant data sets, instructions on computational technologies, and access to data visualization tools and websites.

These large data sets expose students to the kind of real-world data they will encounter in their future careers. With so many variables and data points included, students must learn to work the data and make meaning from all the information provided.

This free online resource from trusted sources shows how interesting exploring data can be. Students will learn to work with raw data and draw meaningful conclusions.

Exercises in the new Discovering Statistics and Data textbook refer to the data sets provided on this curated website.

5 Ways to Get Students Interested in Statistics

Creating a universally engaging classroom environment can be challenging, but having the right tools that make lesson content relevant to students helps! Below are 5 ways to get your students more excited about statistics:

1. Interesting Data
Finding data on topics students think are fun, like beers and breweries across the country, might pique interest. Use this spreadsheet from the U.S. Census to show them socioeconomic trends they may witness themselves in their own demographic (or age bracket).

2. Visualization Tools
Seeing is believing. The free online resource Gapminder offers a graphical simulator depicting 5 dimensions of real-world data in 2D. Students can change the relationships between demographic, economic, and societal variables animated over time to see some pretty neat relationships in motion.

3. Applications Challenge
Knowing the immediate value of the lesson they’re learning gives students more encouragement to commit the content to memory. Asking students to find their own data sets on their favorite sports team or something they connect with might engage their interest and help them truly grasp the concepts.

5 ways to makes stats more relevent

4. Games
You know statistics can (and is!) fun, and who doesn’t like to win? Interacting with a game and trying to win it make learning more exciting. View some examples of statistics games here.

5. Simulations
Help students grasp key concepts through simulations that hold their attention! Use simulations in class and encourage students to work through as a group to liven up the lecture time. Check out fun simulations here.

EXPLORE MORE ENGAGING APPLICATIONS OF STATISTICS


 

Discover relationships with this data visualization teaching tool.

Statistics instructors, have you explored Gapminder yet? It’s one of our favorite data visualization resources! It’s a free site offering many videos and tools, including a graphical simulator depicting 5 dimensions of real-world data in 2D.

Check out how you can use this tool in your classroom to show students the changing relationships between demographic, economic, and societal variables animated over time.

Change the variables to include life expectancy, average income, population, unemployment rate, CO2 emissions, amount of cell phone users, and more. Pinpoint specific historical events to discover their impact through data visualization.

 

  • Correlating development data
    Select Chart and compare different indicators, such as Life Expectancy and Income. What correlations can be found?
  • Analyzing trends
    Try choosing Life Expectancy and analyzing changes over time (select Time for the x axis.) Track selected countries by selecting them, clicking the Trails box, and playing the animation.
  • Mapping development indicators
    Select Map and look for patterns by selecting different development indicators for the countries.
