This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag and evaluate the evaporation rate. Consider having older learners record the actual time taken for complete evaporation and then combining data with the rest of the class and creating a graph of results. Not only can this be used in a physical science setting, but also as part of your water cycle curriculum in earth science.
Fourth graders examine the concepts of evaporation and the water cycle. They describe the relationship between heat energy, evaporation and condensation of water on Earth and identify the sun as the source of energy that evaporates water from the surface of Earth.
Fourth graders study the water cycle and the different processes involved, specifically evaporation. They explore the processes of evaporation through hands-on collaborative activities and relate learning to life through experimentation with evaporation.
Learners explore the concept of evaporation rates in this evaporation rates lesson. They will try to identify the chemical that began a fire, perform an experiment where they use the evaporation rates to determine the unknown liquid, and graph the data using their graphing calculator.
Students analyze physical science by conducting an in-class experiment. In this evaporation lesson, students identify the use of heat to attract water and utilize canning jars, a pitcher of water, and markers to conduct an evaporation experiment. Students complete a worksheet and define a list of vocabulary terms as well.
Learners explain and demonstrate the process of evaporation and conduct an experiment that lead to better understanding of the variables that affect evaporation.
The 3 steps of the water cycle, evaporation, condensation, and precipitation, are the focus of this lesson. After a neat demonstration of rain using hot water, a pie tin, and ice cubes, young scientists observe and discuss the elements of the water cycle. Questions are supplied to prompt discussion; these questions could also be assigned for written work. At the end of the lesson, class members draw the water cycle, labeling their drawings. A useful online resource link is included.
Students study the stages of the water cycle and evaporation. In this water cycle lesson, students read Water Cycles and color a diagram of the water cycle. Students review related terms and sing a song about the Water Cycle. Students then complete a water cycle experiment to study evaporation.
Students review the steps of the scientific method and participate in a three day experiment. They observe water evaporation over time.
First graders explore, analyze, document and study weather and the water cycle. They observe the weather and begin a weather journal. Each student interacts with the concepts of evaporation, condensation and precipitation, clouds, temperature, measuring tools and the effects that weather has on the environment.
Second graders explore water formations by conducting an experiment in class. In this evaporation lesson, 2nd graders utilize Styrofoam plates, water, sponges and crayons to test an evaporation theory while letting their water soak up in the sun. Students discuss their observations and take an Internet quiz based on their understanding of evaporation.
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 of water vary.
Learners 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 weight.
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 hang them to dry while tracking the drying time for different sizes. Note that there are no lab sheets provided; consider having older learners draw up a data table prior to experimenting. Another variation for this experiment would be to compare different types of same-sized paper towel t-shirts.
New! 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 up and asking your class to try explaining how it works. You could also hold the bird's abdomen, warming it with your hand to increase pressure and drive fluid into the head.
Students explore the process of evaporation and the effect of the presence of salt on the process. The water cycle, incorporating evaporation and condensation forms the basis of this lesson.
Young scholars 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.
Fifth graders demonstrate the concept of evaporation by conducting their own experiments, recording their observations. They draw conclusions from their results.
Third graders are presented with the problem of: Do all liquids evaporate at the same rate? The lesson contains adequate background information for the teacher. They participate in a lab experiment in order to test the scientific concept. Observations are made and a summary is written of experimental outcomes in simple terms.
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 the middle, cover bowl with plastic wrap, and leave it in the sun for a few hours. When you check back later in the day, the cup will contain clean, clear water. In the upper elementary and middle school grade levels, this demonsteration would make a perfect addition to an earth science unit on the water cycle.
