Solids, Liquids, and Gases

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Here is the recipe for making ice cream in a couple of zip-top plastic bags. It is a fun way to demonstrate phase changes, especially when the weather is hot! Use this in your elementary science curriculum when introducing the states of...

In this fascinating episode, Mr. Spangler uses cornstarch and water to create a solution known as "non-Newtonian" solution, meaning that the solution doesn't behave in the way that Newton's laws would expect it to. This is one of the...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

There are four states of matter: solid, liquid, gas, and plasma. As this clip describes, the key to changing the states of matter is the addition or subtraction of energy. Learn about molecules, heat, plasma, and the science behind...

Learners complete activities to study the properties of solids and liquids. For this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Learners melt the substances and...

In this fascinating episode, Mr. Spangler uses cornstarch and water to create a solution known as "non-Newtonian" solution, meaning that the solution doesn't behave in the way that Newton's laws would expect it to. This is one of the...
