Water – Changing States (Part 2)
Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one...
National Institute of Food and Agriculture
Water Supply
Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

Physical Changes and States of Matter
Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Chemical Changes to Matter
Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.

Water in the Atmosphere
A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...
Curated OER
Physical Changes to Matter
Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Investigating Physical and Chemical Changes
Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Water Cycle Reading and Writing
After listening to a story about the water cycle, learners create their own versions of this tale. This is a great way to have your class review the concepts of evaporation, condensation, precipitation, and runoff.

The Water Cycle
Fourth graders explore changes in water forms. In this water cycle instructional activity, 4th graders build a water cycle model and monitor it for 2 weeks in order to understand that water changes state as it moves through the cycle.
Curated OER
Water Supply
Fourth graders complete three activities. In this water supply lesson, 4th graders learn that water can exist in different forms and watch a demonstration of each form. Students explore the water cycle and make a water cycle using the...
