After learning about the 3 States of Matter, students can be tested using a pop quiz to check for understanding of the subject, how they transfer from one state to another and also how they are able to illustrates the states of matter either through a drawing of a real life example of the state of matter or the state of matter as a particle. (3.P.2.1, 3.P.2.2, 3.P.2.3)

In this activity students test a variety of liquids and solutions to see which conduct electricity. Note: This is designed for use in a science museum or education center and may need to be modified for classroom use.

This article aligns the concepts of Essential Principle 2 of the Climate Sciences to the K-5 content standards of the National Science Education Standards. The author also identifies common misconceptions about heat and the greenhouse gases effect and offers resources for assessing students' understanding of interactions among components of the Earth system. This article continues the examination of the climate sciences and climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured.

In this lesson, students will observe the differences between solids, liquids and gases. They sort different liquids as to their physical properties. Finally, they observe how food coloring mixes in water, club soda, and salt water.

Students add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules. Students watch molecular model animations to make further observations and then draw their own molecular model.

This article explains how the ice and snow of the polar regions fit in the global water cycle and includes links to professional development resources.

Four unit plans provide opportunities for in-depth explorations of important foundational climate concepts -- weather, water as a solid, liquid and gas, and the water cycle -- that are appropriate for K-2 and 3-5 learners. These unit plans incorporate many of the lessons highlighted in other articles in this issue of the online magazine Beyond Weather and the Water Cycle. The magazine is structured around the essential principles of the climate sciences.

This is an encyclopedia entry for the term "rain." Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Text for this entry is appropriate for the middle and high school grade levels.
