Introduction to Dissolved Oxygen and Demonstration of a Simple Test Procedure

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...

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...

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...

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...

Curious physical scientists follow a activity on the properties of water with this activity on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

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...

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...

Young scientists get their feet wet as they learn about the water cycle in this series of activities. Whether they are observing how evaporation causes puddles to dry up, or how plants put water into the atmosphere through...

A website links you to several water cycle worksheets geared toward an upper elementary or middle school level. Diagrams, word search, crossword, and fill-in-the-blank worksheets are available. As an added bonus, there are links to...
