There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

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...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Here is part two of a two-part lesson plan 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...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

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...

Here's a wonderful lesson on how substances change states. Groups of learners are given trays with a chocolate bar, a piece of paper, an ice cube, and a balloon. During the activity, the groups closely observe the changes that each...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...
