Key Graphing Vocabulary

These are the graphing words you will see on the California Science Test (CAST). Use this page to build clear, simple notes in your science notebook.

Goal for this page

• Learn what each graphing word means in student-friendly language.
• Practice using phrases like "According to the data..." and "The graph shows...".
• Get ready to read graphs, build graphs, and answer CAST-style questions.

Notebook Task

• Write each starred term and its definition.
• Next to some terms, copy a mini-sketch or tiny graph that fits the word.
• Leave space to add examples from class labs later.

Definition & Notebook Note

Use this panel while you write notes. Keep your sentences short, clear, and in your own words.

Notebook idea: Draw a small blank graph and label the x-axis and y-axis. Leave room to fill in real data later.

Evidence Language Bank
Use these sentence starters in your notes and answers:
The graph shows that..., According to the data..., Based on the trend..., The evidence suggests...

Build Your Own Graph (for your notebook)

• Make a quick table: time (minutes) vs. temperature (°C) for a cooling drink.
• Choose the correct graph type (line, bar, scatter, pie) and draw a small sketch.
• Below your sketch, write two sentences using the language bank to describe the trend.

Practice – CAST-Style Questions

Answer these based on the vocabulary you just studied.

1. A graph shows enzyme activity on the y-axis and temperature on the x-axis. Which phrase correctly uses graphing language?

I think the line is kind of cool. According to the data, enzyme activity increases as temperature rises up to 37 °C. The x-axis is probably time. The dots are just random pictures.

2. A scatter plot shows a negative correlation between pH and reaction rate. What does this mean?

The reaction rate does not change. Both pH and reaction rate increase together. As pH increases, the reaction rate tends to decrease. One point is far away from the others.
