Investigate the properties of a strange substance which acts like a liquid and a solid. This simple experiment can be done with corn starch and water.

This set of interactive flashcards focuses on 20 terms related to Solids, Liquids, and Gases (the three states of matter).

This interactive assessment features 7 matching, 7 multiple-choice, and 6 true/false questions over 20 terms related to Solids, Liquids, and Gases (the three states of matter).

Kid's learn about the science of melting and boiling. How matter changes state from solids to liquids to gases.

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Kid's learn about the science of states of matter. Solids, liquids, gases, and even plasma.

A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

In this lab experiment, students will use 4 solids and 6 liquids to create colorful, layered rows demonstrating that less dense materials will float on top of the more dense materials.
