The Energy of Evaporation
Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

Dry My Laundry!
Meant to be a pre-field trip lesson, this can also serve as a cute and simple activity to use when your little ones are learning about evaporation or surface area. The children cut tiny t-shirts out of paper towel material, wet them, and...

Worksheet 3: Earth's Climate System II
A diagram of a mountain range and the prevailing winds is shown at the top of the page. Meteorology pupils describe the weather conditions at different points on the diagram. They explain the El Nino effect and why evaporation and...

Why Does a Puddle Shrink?
Fourth graders describe the relationship between heat energy, evaporation and condensation of water on Earth. They compare evaporation rates when the back of the hand and an equal area of a paper towel are moistened with the wet swab.

A Day at the Beach
Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

It's Clean, Fresh and only Three Billion Years Old - Water!
Students engage in a lesson which explores the wate cycle. They get to see some very entertaining video, do fun hands-on activities and gain a better understanding of evaporation, condensation, precipitation and collection.

Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

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,...

Evaporation Pans & Related Rates
Students calculate evaporation rate using differential equations. In this calculus lesson, students explain how pan evaporation works. They complete a worksheet to sum up the lesson.
Curated OER
The Atmosphere and Flight
Students investigate evaporation and condensation, and apply the concepts to understanding cloud formation.

Evaporation
Students break into small groups with four or five students per group. Each is given a styrofoam plate on which they write their group name on and 2 teaspoons of warm water. They place their plate on a paper towel somewhere in the room...

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...
