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.

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.

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 instructional activity is used early in the Chemistry course. The students...

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.

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...

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.

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)...

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

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.

In this lesson, students learn about physical and chemical changes during digestion through a variety of activities.

An individual organism's genes determine its physical and behavioral traits. When individuals reproduce, they pass along unique combinations of genes to their offspring. Different environments favor individuals with different physical...
