Heat and Temperature — Vocabulary Match

About this worksheet

This vocabulary match printable supports K-2 learners working on Heat and Temperature. A two-column matching activity where students draw lines from each science vocabulary word to its student-friendly definition. Excellent as a warm-up or end-of-unit review. Use it as guided practice during your unit, as a take-home review, or as a quick formative check before moving on to the next concept. The activity is aligned to NGSS performance expectation 2-PS1-4 and pairs cleanly with hands-on demonstrations, picture books, and short videos already in your classroom rotation. An answer key with teacher notes appears at the bottom of this page so you can grade in seconds and identify common misconceptions before they harden.

Learning objectives

• Compare hot and cold using a thermometer.
• Explain that heat moves from warmer to cooler.

Practice exercises (10 questions)

Print this section for students. Reveal the answer key below for grading.

1. In your own words, a thermometer measures temperature.
2. State the learning objective for Heat and Temperature in your own words.
3. Give one real-world example that shows some materials trap heat better than others.
4. Why is it important for a scientist to know that a thermometer measures temperature?
5. How would you explain to a younger student that heat moves from warmer to cooler objects?
6. Draw a quick sketch that shows some materials trap heat better than others. Label two parts.
7. Compare a thermometer measures temperature with one other idea you have learned in this unit.
8. Which everyday observation would best support the idea that heat moves from warmer to cooler objects?
9. Predict what would happen if some materials trap heat better than others were not true.
10. Write one new question you still have about a thermometer measures temperature.

Teacher notes

Watch for these common misconceptions: A thermometer measures temperature. Many students will guess based on appearance instead of evidence — encourage them to point to a specific clue from the passage or diagram. For early finishers, ask them to draw their own example or write a one-sentence summary on the back of the page.

How to use in class

Print one copy per student, or project the page on your board for a whole-class discussion. The vocabulary match format works well as a 10-15 minute activity within a 45-minute science block. Younger students may need the directions read aloud the first time you use this format; once they have done one or two, they can usually start independently. For early finishers, ask them to flip the page over and either draw an example from real life or write one new question they still wonder about. Both options stretch their thinking without requiring extra prep from you.

If you are teaching this unit in a multi-grade classroom or a homeschool setting with siblings of different ages, scaffold by reading the first two questions aloud with the whole group, then release younger students to work in pairs while older students complete the printable independently. The reveal-on-click answer key keeps the page free of distractions while students are working.
