[Free Registration/Login may be required to access all resource tools.] Covers reversible and nonreversible changes.

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

In this activity, learners investigate physical and chemical changes in the states of matter for water. They collect data and record their observations.

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.

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

Explains the difference between chemical and physical changes.

Learners will create an endothermic chemical reaction by making ice cream. They will observe, describe, and measure the ingredients. After making ice cream, students will measure the temperature of the ice cream and the ice/salt mixture....
