Evaporation and Condensation gives Grade 4 students focused physical science practice with two important changes of state. Students explore how liquid water becomes water vapor through evaporation and how a gas cools and changes back into liquid through condensation.

Changes of State in Action

This resource helps students connect changes of state to what happens at the particle level. They describe evaporation as liquid water changing into water vapor as particles escape into the air, then explain condensation as a gas cooling and forming liquid again on cooler surfaces.

Students also compare evaporation and condensation by linking each process to temperature changes. Key vocabulary is used throughout the activities so students can complete sentences and answer questions using accurate language about changes of state.

Practice and Scientific Reasoning

The worksheet combines multiple-choice questions, true-or-false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. Students identify processes, compare changes of state, apply vocabulary, interpret information, and explain scientific ideas in written responses.

Included Resources

• ✅ Grade 4 physical science worksheet on evaporation and condensation
• ✅ Student Notes lines at the bottom of the worksheet
• ✅ Separate Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Application

Use this Grade 4 science worksheet after teaching changes of state, as independent practice, during a physical science lesson, or as a review activity. The combination of selected-response, reading, diagram, and written tasks gives students multiple opportunities to describe and compare evaporation and condensation.

The accompanying Teacher Guide supports instruction with learning objectives, teaching tips, discussion questions, and common mistakes. It can help teachers reinforce the connection between cooling, heating-related temperature changes, particle movement, and the transition between liquid and gas.

Key Vocabulary and Concepts

Students work directly with evaporation, condensation, water vapor, particles, temperature, cooling, liquid, and gas while explaining how matter changes state. The resource uses a General framework and is designed for Grade 4 physical science instruction.
