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...

Here is a terrific earth science lesson on the water cycle that's designed for grades two to five. In it, understanding of the water cycle will be enhanced. The lesson focuses primarily on evaporation, and what happens to the water vapor...

Sixth graders explore the factors the effect evaporation.  In this evaporation lesson, 6th graders work in groups to experiment with various plants to find the water contained in it.  Students answer questions based on their inquiry....

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...

First grade scientists learn about changes in the state of matter, but here is a presentation that explains it at a high school level. Illuminating graphics and photos enhance understanding, and the information is disclosed in an order...

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.

What are the properties of water? Lead your class through a series of activities to answer this question. Discuss findings and interpretations with the class as a whole, encouraging them to speak in complete sentences and to make...

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,...

The water cycle is a fascinating process! Introduce young scientists to the water cycle using a colorful worksheet. Complete with "before reading," "during reading," and "after reading" questions, this presents the water cycle to...

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. Learners sing about the water cycle and discuss what...

Vapor pressure is the focus of this chemistry video. Sal explains that, when molecules are "sticking together" a substance takes on a liquid, or a solid form. But when kinetic energy is increased, the molecules are forced apart and a...

Discuss where we find water and the source of rain with your kindergartners. The basics of the water cycle will become more clear as they sing songs and participate in an experiment where they see the stages in the water cycle.

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...

The water cycle is the focus of this technology and Earth Science lesson. Third graders complete a webquest to gain understanding of the water cycle. As they navigate through the Web Quest, they also begin the process of creating a...

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...
