Episode 35: Teaching Graphing Skills to High School Science Students: A Step-by-Step Approach

Have you ever asked your students to make a graph, only to discover that they have absolutely no idea where to start? Yep, that happened in my classroom! 😅

After years of teaching students who already knew how to graph, I realized that many of my current freshmen were struggling with some pretty basic graphing skills. Choosing an appropriate scale, plotting points, calculating averages, and using data to support a claim were much harder for them than I expected.

So, instead of continuing to hand out graphing assignments and hoping for the best, I decided to slow things down and teach the process one step at a time.

In this episode of The Confident Chemistry Teacher Podcast, I'm sharing how I broke a graphing activity into five manageable lessons, what actually happened when I tried it with my Biology students, and how I'm planning to incorporate more explicit graphing instruction into my high school chemistry classroom.

🧪 In This Episode, You'll Learn:

• Why we can't always assume high school science students already know how to construct and interpret graphs.

• How I broke teaching graphing skills into five short lessons, from identifying independent and dependent variables to choosing scales, plotting points, and analyzing data.

• Which graphing skills my freshmen struggled with the most—and what I'm doing to help them improve.

• How scientific graphing activities can strengthen mathematical reasoning, data analysis, and claim-evidence-reasoning (CER) skills.

• Practical ways to incorporate graphing into chemistry lessons on density, atomic structure, periodic trends, chemical reactions, gas laws, and solutions.

📊 Graphing Skills: It's Not Just About Making the Graph!

One of my biggest takeaways from this experience was that students weren't unwilling to graph. Many of them genuinely didn't know how, and they needed someone to walk them through the process.

By breaking graphing into smaller steps, my students were able to build confidence and focus on one skill at a time. And guess what? Several of them even asked for more practice!

I'm also realizing that graphing shouldn't be something we teach once and then forget about. Whether students are creating a density graph in Chemistry, analyzing population growth in Biology, or interpreting data in AP Environmental Science, these skills need to be practiced throughout the school year.

My goal moving forward is to make graphing a more intentional part of my science lessons, so students can become more independent and confident when working with scientific data.

Not sure where to start when teaching graphing skills? I've put together a Scientific Graphing Reference Sheet to help students understand the different types of graphs and when to use each one.

It's a handy resource to keep available as students work through graphing activities in your chemistry or science classroom!
