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...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

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...

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.

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

Practice comparing and contrasting details in informational text with a reading passage about whales. It explains the ways that fish and whales are similar, as well as the ways they are different, and specific characteristics of various...

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

[Free Registration/Login may be required to access all resource tools.] Provides the definitions of physical and chemical changes in matter and gives examples. The law of conservation of mass is also described.

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...

Can you distinguish physical changes from chemical changes? After reading a brief summary of both types of changes, you'll be presented with some examples and asked to identify them.

Can you distinguish physical changes from chemical reactions? You'll be presented with a number of pictures and asked to identify those which are examples of chemical reactions.

In this lesson, students match a substance with its state of matter, identify what state something is, and learn about temporary and permanent changes in matter.

Students will learn the difference between physical and chemical properties of matter.

[Free Registration/Login may be required to access all resource tools.] What happens in a chemical reaction is explained, along with how it is represented by a chemical equation. In a chemical reaction, the law of conservation of matter...

A series of interactive applets use scientific models to teach some basic concepts of matter, including states of matter and physical and chemical changes.

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, young scholars use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

A comprehensive lesson plan site that contains a number of activities to aid in teaching about the states and properties of matter and the difference between a physical and chemical change.
