We tend to make a big deal out of Presidential elections on K-12 campuses, but sometimes leave out the midterms. Use this historic midterm election season to illustrate how STEM concepts are inextricably linked to campaigns and elections.  Here are three ways to do this in your classrooms or at home.

 1.  STEM-ify Your Mock Election  

Probability and Statistics: Collecting that Exit Poll Data!

Have your students devise an efficient system for collecting exit poll data during a mock election. Start by explaining that even though elections outcomes aren’t official until the polls close, exit polling is used to project outcomes as media organizations want to begin announcing winners as soon as possible. Additionally, exit poll data is used to analyze outcomes post-elections (e.g. why or how a certain demographic group voted overall).  

Ask your students:

    • Do you think it would be possible to collect data from every single voter? Why?
    • What is a representative sample? How would you determine a representative sample? For example, if you know that 50% of voters in your mock election are in 4th grade, and 40% are in 5th, then what would your representative sample have to include? Upper grades: you can also discuss margin of error- what it means and why it is used.
    • What is the most efficient method for collecting exit poll data? Will you use low-tech (e.g. paper survey or phone bank), or high-tech (e.g. touch-screen device such as an iPad)? Why? What are the potential benefits to each?
    • What outcomes do you predict based on the data you collected? How will you choose to present this data?
    • Compare: How did your exit poll predictions compare to actual election results? If different, where were the errors in your polling methodology? How can they be corrected?
    • What are the benefits of polling? Potential issues? Here is a short article on Polling Pitfalls.

Graph it!

Post mock-election, have your students choose their own way to graph the results. For example, depending on the data collected, they may break down results by demographics such as gender, race or ethnicity, grade level, etc. They may choose a scatter plot, bar graph, line graph, Histogram or other method of representing the data. Have students share their graphs with the class and ask guiding questions such as

  • How does the way information is presented on a graph change our interpretation of it?
  • Why might you choose one type of graph to represent your data over another?
  • What surprised you about this graph? Why?What types of unsolicited political ads do they see, if any?

2Instagram Videos and Algorithms this Election Season

Algorithms are problem-solving operations used by social media channels such as Instagram or Snapchat to process user data collected by companies and apply it to what posts, advertisements or stories they see in their feed and how they are able to interact with them.
Explain that these algorithms impact what types of political ads or news stories students may see on their feeds. As a homework assignment, have them analyze their own social media feed channels (or a family member’s if they don’t have their own) and consider the following questions in a journal entry:

  • What have they posted on their feed or what groups do they follow that their social media feed may have collected data about?
  • Do the political ads or stories align to their personal beliefs? If so, what assumptions might they make about other people who support similar candidates or issues?

Here is a short article on Instagram’s feed.

  3. Civics STEM PBL

This is a great time to demonstrate to your students that our lived world is an interdisciplinary one.  Plan some fun activities with social studies teachers.
