Exploring Cell Phone Usage versus GPA With This Graphing Activity

Are you a science teacher looking for engaging ways to incorporate real-world data into your lessons? This Cell Phone Graphing activity is a fantastic way for students to explore the relationship between cell phone usage and academic performance through hands-on data analysis. By graphing actual research findings, students will gain valuable insights into the scientific process and strengthen their graphing skills. Let’s dive into how this biology graphing activity can be an impactful addition to your curriculum!

Scenario Overview

In this activity, students will analyze data from a hypothetical study that investigates whether there is a correlation between cell phone usage and academic performance among college students. This setup helps students explore questions related to the impact of screen time on GPA—a relevant topic in today’s digital age.

Background and Relevance

As smartphones have become integral to daily life, researchers have raised concerns about the potential effects of screen time on academic outcomes. This study specifically examines whether the time spent on cell phones correlates with students’ GPA. By diving into this investigation, students will better understand how lifestyle choices can impact educational performance, making the data both relatable and relevant.

Experimental Design in Focus

For this activity, students will work with data collected from a sample of college students who participated in an experiment:

  1. Data Collection: Each participant’s cell phone usage was automatically logged using an app installed on their phone, tracking hours per day spent on the device.
  2. Academic Performance Measurement: Students’ GPAs were recorded as a measure of their academic performance.
  3. Controlled Variables: To ensure consistency, participants reported having similar study habits and extracurricular commitments, providing more reliable data for analysis.

Student Graphing Task

Using the data provided on cell phone usage and GPA, students will graph the results to visualize potential trends and correlations. They will learn how to interpret the graph’s structure, identify patterns, and discuss any observed relationships between the variables.

Teaching Objectives

This biology graphing activity aligns with core educational objectives in science:

  • Data Interpretation Skills: Students will practice interpreting theoretical data by plotting hours of cell phone use against GPA, which encourages critical thinking.
  • Understanding Correlation: This activity introduces the concept of correlation versus causation, helping students recognize that even if a trend exists, it may not imply causation.
  • Real-Life Application of Biology Concepts: By examining the impact of technology on biological behaviors like study patterns, students will see relevance to everyday life.

Graphing Worksheet

Graphing Worksheet

In this weeks free worksheet I wanted to share with you a graphing  worksheet. We all know our students need more time and practice graphing.

In this graphing worksheet  students watch the videos on graphing from Paul Anderson at Bozeman Science. Students follow along in the video and answer questions on the Graphing Worksheet that I created to go along with the videos. Students  create their own graph and compare it to the one in the video and record their differences.

This activity is a great way to introduce graphing to your students. Sometimes as teachers we just expect that students come to us with these skills but  we need to teach it to them or at least remind them of the proper way to set up and read a graph.
