Explains what a chemical change is and how to identify one. Provides examples of chemical changes that are often seen in organic and inorganic compounds.

Chemical change is a section of a larger overview on Chemistry, covering a variety of aspects. This section focuses on chemical change including the difference between chemical change and physical change.

Dynamics of chemical change is a section of a larger overview on Chemistry, which covers a variety of aspects. This particular section focuses on kinetics and mechanism, kinetics, and catalysts. Examples, formulas, and pictures are...

Energetics of chemical change is a section of a larger overview on Chemistry, which covers a variety of aspects. This section focuses on energetics and equilibrium, and chemical energetics. Examples, formulas, and pictures are provided.

In this activity, students will observe another aspect of a chemical change which is a change in temperature. In this reaction, students will experiment with an endothermic reaction.

Students will observe an exothermic reaction in this activity where they add calcium chloride to a baking soda solution. This increase in temperature is due to the chemical change that has occurred.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...

Understand the rates and mechanisms of chemical change. These topics stand in contrast to the subjects of equilibrium and thermodynamics that control the direction of chemical change.

Learn about color change and pH as it relates to chemical changes.

The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter.

Students will conduct two chemical reactions: endothermic and exothermic. They will see an animation that shows that it takes energy to break bonds and that energy is released when new bonds are formed, and use that animation to explain...

Students will use scientific methods in creating and observing a chemical reaction.

An activity that allows students to discover the active ingredients in baking powder by studying chemical change. Lab activity includes both teacher and student instructions.

See how temperature changes affect dissolving and the molecular bonds in a water molecule.

Using an illustrated example, the difference between an endothermic and an exothermic reaction is described. The concept of enthalpy, or heat energy change, is explained, and the energy diagrams of reactions are presented.

What's the Matter? is a guided inquiry lesson on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson: (a) concentration game for definitions and (b)...

Use these demostration video clips to help understand the energy changes in some chemical reactions.

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This lesson is used early in the Chemistry course. The students love it. This...

Explains how Le Chatelier's Principle is used to predict how a temperature change affects a system's chemical equilibrium and presents a virtual experiment where the effect is explored. Requires Java.

Energy can be described as being in different "stores". It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways. There are seven main stores of energy: magnetic, internal (thermal), chemical,...

Explains how Le Chatelier's Principle is used to predict how a volume change affects a system's chemical equilibrium and presents a virtual experiment where the effect is explored. Requires Java.

Explanation of Noble gases and of how atoms attempt to fill their outermost valence shells for stability.

This site provides an excellent overview of the solution process. Content includes a focus on how a solution is formed, energy changes and solution formation, spontaneity and disorder, and solution formation and chemical reactions.

Neurotransmitters can either stimulate the next neuron to send a signal or inhibit that neuron from sending a signal. Certain chemicals change the way signals are sent and received. In this lesson young scholars will understand this...
