Curated OER
Physical Changes and States of Matter
Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

The First Farmers
Students show how constant irrigation, with repeated evaporation of water that left salts in the soil, eventually ruined much farming land in southern Mesopotamia. They discuss the idea that with the development of irrigation people...

Biocomplexity Lab Activity: Creating Salt Water
The lesson plan seeks to intorduce to students the properties of salt water and how to create salt water. Teacher gives backgound information about salt water to students. From that point, students dscuss what elements are in salt...

Lose Some Weight- Evaporate!
Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...
Curated OER
The Rain Maker
Second graders work in small groups with a cup each of several materials. Students layer the gravel, sand, and water into a resealable bag. They draw a picture of this bag in their water journal. Students place their sealed bags in a...
Curated OER
Lesson 4 Lesson 2(cont.) Its a Small World (Day 4)
Students watch and discuss observations of condensation on the plastic "sky" of the container. They draw a sketch of what they see and record their observations on the Its a Small World mini booklet. Sudents investigate evaporation...
Curated OER
How Effective is Perspiration at Cooling?
Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.
Curated OER
Factors affecting infiltration and runoff
Young scholars investigate some of the factors that determine the amount of runoff. They are reminded that infiltration and runoff tend to work oppositely. When conditions are bad for infiltration they usually lead to runoff.
Curated OER
The Water Cycle
Middle schoolers describe the water cycle. Students identify the processess in the water cycle. They draw an illustration of the water cycel with arrows showing the path water takes through the cycle. Middle schoolers label condesation,...
Curated OER
Weather and the Water Cycle
Second graders discover the causes of different types of weather. They draw pictures of the water cycle steps and answer worksheet questions. Students observe teacher-conducted demonstrations exemplifying condensation and evaporation.
Curated OER
Water/Agua
Third graders complete water activities including vocabulary, visualization and performing activities. They study water vocabulary words in both English and Spanish. They listen to a read aloud of Jane Yolen's, Letting Swift River Go,...
Curated OER
Ecology
Pupils identify and describe three states of water. They predict how water will change states.
Curated OER
Rain, Rain, Go Away
Young scholars conduct a number of experiments involving evaporation and condensation. They view and discuss a video about the water cycle and then design posters about the rain based on the book "Cloudy With A Chance of Meatballs".
Curated OER
Watercycle
Third graders examine the natural circulation of water from oceans, lakes, and rivers to evaporation into the air, and then to condensation to produce rain falling back to the soil as components of the water cycle.
Curated OER
Miniature Water Cycles
Fourth graders create a biome of their choosing in a terrarium. Terrariums are observed and results recorded daily for 2 weeks. They observe/record changes in the water within their terrarium and use the data to write sentences...
Curated OER
Earth: The Water Planet
Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.
Curated OER
Water Cycle
Students perform experiments with water to observe the principles of evaporation and condensation. They make models of the water cycle and discuss the processes that occurred in their experiments with their jars of water.
Curated OER
Evaporation Marathon
Students review the steps of the scientific method and participate in a three day experiment. They observe water evaporation over time.
Curated OER
EVAPORATION/HUMIDITY
Third graders generate ideas as to where water goes when it disappears, predict what happen to water left on a plate overnight according to its' location, the evaporation of water on plates and come to a conclusion as to why the amounts...
Curated OER
Water Into Gas
Students investigate how temperature and pressure cause a material to change phase. They heat water to reclaim a gas. They demonstrate that different liquids evaporate at different temperatures.
Curated OER
The Atmosphere and Flight
Students investigate evaporation and condensation, and apply the concepts to understanding cloud formation.
Curated OER
Sunken Millions: 3rd Grade
In this PowerPoint, students participate in a game with a quiz show format in which they answer questions about water. Topics include the water cycle, bodies of water, characteristics of water, and how water relates to weather...
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.
