Everything around us changes, but scientists classify the ways matter changes as either a physical or chemical change. This unit helps students understand the difference between these two kinds of changes and explores common examples of each. Additional chemistry concepts such as boiling point, freezing point, melting point, condensation, sublimation, oxidation, and the first two laws of thermodynamics are also explored. Numerous diagrams are given to help make these concepts accessible and easier to understand.
At the end of the unit, students can review 14 vocabulary words and enjoy a review activity. Answer keys are provided. 17 pages total. Ages 11-13.
All measurements are given in both English and metric. This title does not discuss origins or the age of the earth. If you would like to explore the topics in this book from a Creation science worldview, free downloadable discussion helps are available.
