Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

What a great resource! This presentation is informative as is, but there are links provided to some great resources that can help learners explore the states of matter in greater depth. For example, there is a link to a website that...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

This presentation gives information about the kinetic theory behind particle motion at different energy levels and states.  The effect of temperature on energy content and the resulting changes in state are covered at a molecular...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

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....

A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

A somewhat strangely formatted slide show that contains multiple examples of matter types. The classification and state explanations given would be useful as practice of substance identification and the heating curve may prove to be...

The states of water are the focus of this PowerPoint. The presentation includes definitions of liquids, solids, and vapors. It also includes examples and illustrations of each of the states of water and information about how water can...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

This PowerPoint enables students to review concepts about the states of matter. This interactive review game provides students with an opportunity to demonstrate their knowledge of subject specific vocabulary.

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...

Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

By viewing this PowerPoint your students' understanding of molecular energy should increase. The properties and inter-particular forces are summarized. The logical progression of information is useful, but more data to demonstrate...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

How does matter change and what are its properties? This presentation is a bit scattered and attempts to infuse humor in place of concrete definitions. In order to make this worthwhile for classroom use, you will need to add to it.

Some scientists argue that air pollution now causes more deaths than smoking. The second unit in a six-part series focuses on air quality. Scholars learn what's in the air, how clean the air around their school is, and what they can do...
