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...

Crystallize the answer to the question that has been investigated since the first of four lessons: What is the unknown crystal? Pupils have examined, crushed, and dissolved four samples plus an unknown as an exploration of the properties...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

Incorporate art and poetry into an early elementary science lesson about cloud formation. With fun and engaging activities that follow a natural learning progression, youngsters will develop key vocabulary and conceptual understanding...

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...

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

Fifth graders explore the major components of the water cycle. They pay close attention to evaporation, condensation, and precipitation. A water cycle kit is set up in the classroom, which learners observe for a couple of days before the...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Diagrams bring barometers to light in this PowerPoint. Several slides explain the structure and function of this apparatus. The relationship of air pressure to the processes of evaporation and boiling are also explained. This would be an...

Students investigate the water cycle by performing a simple hands-on activity using a plastic container, plastic cup, a rock, and a reflector lamp. They observe the model and measure the water level from time to time.

Young scientists investigate the water cycle through a lettuce seed experiment. For this experiment, learners plant lettuce seeds inside of a ziplock bag in order to create a small greenhouse. They observe condensation and precipitation,...

After conducting experiments with a sponge, ice water, and a soda bottle your young scientists become familiar with the water cycle through experiment, song, hand motions and drawing. Students sing about the water cycle and discuss what...

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

To prepare for a performance task assessment, class members review the stages of the water cycle and then individuals assume the roles of drops of water for a Reader's Theater exercise. The script, a graphic depicting the water cycle,...

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...

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...

Use this as a pop quiz when covering the water cycle with your elementary earth scientists. There are five blanks to fill in, including the three main steps (evaporation, condensation, and precipitation), and also transpiration and...

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...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

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...

Students analyze the impact of climate variability and change utilizing a broad span of topics over a wide range of grade levels. This three lesson unit is easily adapted for the various instructional levels listed.

Here are the instructions for leading your advanced chemists though the process of measuring the nonvolatile components in a sample of paint. No student handout is provided, so you may want to create one based on the procedure explained....

As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity....

An inventive and interesting lesson on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved in the...
