[Free Registration/Login may be required to access all resource tools.] Discusses refraction of light in matter and how light changes its speed and angle of refraction according to the type of medium it is travelling through.

Students will use their prior knowledge about changes of matter to develop a hypothesis to test the physical properties of materials such as plastic (polymers) and how its chemical properties allow it to have unique physical properties.

Learners are given a scenario for this lesson where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an experiment with...

This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

With an overview of the various properties of the states of matter, this 18 page pdf file provides a series of topics related to liquids including special physical properties of liquids, changes of state, and more.

A very descriptive site that allows students to understand the different states of matter at the atomic level. Also discusses the process of phase changes and displays phase change graphs. Thermochemistry is also touched upon for high...

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

[Free Registration/Login may be required to access all resource tools.] Refraction of light in matter and how light changes its speed and angle of refraction according to the type of medium it is travelling through.

This lab is designed to have students find the relationship between the number of pulleys used and the force required to lift a mass. Students will see that it is not actually the number of pulleys that matter, but the number of strings...

This site provides a lesson plan using candy making to demonstrate physical and chemical changes in matter. Includes directions to make caramel and rock candy.

The chemical change of matter is illustrated in this lab experiment when spaghetti is placed in a solution of baking soda and vinegar. Watch the spaghetti rise to the surface and sink again once the gas is released.

In this experiment, three reactions are performed in a sealed Ziploc bag so that they can be observed. Students identify whether physical or chemical change has taken place.

Find out your or your students' basic knowledge of concepts like matter, molecules and open and closed systems. Afterwards you can see how others answered the questions.

[Free Registration/Login Required] An informational text about how cooking causes changes in matter. A question sheet is available to help students build skills in reading comprehension.

A module that provides the definition of chemical property and examples of the chemical properties of matter using explanations, pictures, and review questions.

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

At this resource discover the difference between solids, liquids, and gases. Practice what you just learned with included review questions.

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