Water Purification by Evaporation and Condensation
This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

How Can Clouds Keep the Air Warmer?
Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...
Oceanic Research Group
Heat Transfer and Cooling
Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...
American Chemical Society
Condensation Station
Where does the water come from? Pupils conduct an experiment to learn more about condensation. Scholars fill two cups with ice water and isolate one from the surrounding air. They then use a coffee filter to compare the amount of water...
American Chemical Society
Evaporation Sensation
Where did the water go? Learners conduct an experiment to see how the difference in temperature affects evaporation rates. Scholars continue to investigate evaporation by comparing water and alcohol evaporation rates. Pupils experiment...

Physical Changes and States of Matter - Two
Here's a wonderful lesson on how substances change states. Groups of learners are given trays with a chocolate bar, a piece of paper, an ice cube, and a balloon. During the activity, the groups closely observe the changes that each...
Fuse School
Quiz: Solids, Liquids and Gases
Time to show what they know! Module five in a 14-part series about solids, liquids, and gases redirects to an interactive quiz. Learners test their skills on topics such as states of matter, phase changes, and Brownian Motion. With...
Curated OER
Evaporation and Condensation
Young scholars explore how temperature affects the processes of evaporation and condensation.
Curated OER
Water Changes and Moves
Students explore the three forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson.

Study Jams! The Water Cycle
Will tomorrow's soccer game be rained out? That depends on the water cycle. An animated feature explains precipitation, evaporation, transpiration, and condensation with diagrams and dialogue between Sam and RJ as they huddle under a...
Curated OER
Evaporation and Condensation
Students explore how temperature effects the processes of evaporation and condensation and how the air may be polluted by the evaporation of certain compounds. In this temperature lesson students complete a lab and a worksheet.
Exploratorium
The Dipping Bird
If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...

Physical Changes and States of Matter
Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...
Baylor College
What Is the Water Cycle?
Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...
