Graph annotations help students make sense of complex data by labeling important points and providing context. With annotations, students can understand relationships between different data sets and draw their own conclusions. Graph annotations are a powerful tool for science. Put simply, annotations are labels, notes, or symbols that are added to a graph to provide more information and context.
What are graph annotations?
Annotations highlight key data points, explain trends, or add clarity to complex information. And, they come in many forms, including text labels, arrows, shapes, or even images. By adding them to a graph, you can make it more informative and easier to understand. Overall, graph annotations take your data analysis to the next level.
How to Annotate a Graph
Students add a wide range of marks to make their graphs easier to read. These can include arrows that point out specific data points, boxes that highlight important sections of the graph, and text boxes that explain the meaning of the data.
However, it’s best to develop a shared set of symbols and marks for the class to use. This helps students to understand what is expected in a graph annotation. Also, by standardizing these symbols and marks, students create clearer and more consistent annotations. As a result, this makes it easier for them and their classmates to understand the graphs presented in class.
Scaffolds for Graph Annotations
To scaffold graph annotations, there are several methods that educators can use.
For example, provide students with arrows pointing to specific data points and blank text boxes to fill in. This provides students with a clear indication of what they need to explain and what types of annotations are required. And, by scaffolding them in this way, teachers help students to develop the skills they need to interpret and communicate data effectively.
Alternatively provide students with a guiding question. This helps students to focus their annotations on specific aspects of the data.
As with all scaffolds, choose the lowest level of support that students need in order to be successful. Then, when students are comfortable with annotations, remove these scaffolds.
Digital Graph Annotations
Presentation software (including online platforms like Google Slides™) allows students to freely move items around their page. In contrast, word processing software uses an in-line format. So, this limits the ability to add annotations.
Check out this video to see how it works.
Alternatives to Google Slides
Microsoft Powerpoint is a similar platform. It would give students the ability to move items around on their page. Also, Google Drawings provides additional features to help with graph annotations. However, I find students have more difficulty annotating their graphs in Google Drawings.
Graph Annotations and the NGSS
Graph annotations play an important role in helping students meet the Next Generation Science Standards (NGSS). They help students develop their ability to communicate their findings in a clear and concise manner, which is another important skill emphasized in the NGSS. By requiring students to create and interpret annotations, educators help students build the scientific literacy they need to succeed in the 21st century.
Connections to the Science and Engineering Practices
Analyzing and interpreting data is a key practice of NGSS. Scientists must collect, organize, and interpret data effectively. NGSS aims to help students develop these same skills. Graph annotations are a powerful tool for helping students understand scientific data.
Using Graph Annotations to Support an Argument
Graph annotations can be a valuable tool for helping students learn to engage in scientific arguments. By having students create annotations that identify specific parts of a graph and explain both what they see and what it means, educators can help students to develop the skills needed to support their claims with evidence and reasoning.
When I have students create graph annotations, I use the prompt “What do you see? What does it mean?” from this resource created by Nicole VanTassel of iExplore Science. And, this scaffold works for developing scientific arguments. The items that they “see” are used as evidence. When they explain “what it means” they are developing reasoning.

What else can you annotate?
Annotations aren’t just limited to graphs. This strategy works for all types of data. For example, this strategy also works when students are reviewing maps.
Graph annotations help students understand complex data. There are many ways to annotate a graph, including creating a shared set of symbols. Also, these annotations help students meet NGSS standards and develop the skills needed to engage in scientific arguments. Ultimately, graph annotations are a powerful tool for making data visualizations more accessible and engaging for students.
