Welcome toGOd’SDESIgN®fOR chEMISTRy & eCOLOgy ou are about to start an exciting series of lessons on chemistry and ecology. God’sDesign® for Chemistry & Ecologyconsists of three books:Properties of Matter,Properties of Atoms and Mol-Y ecules,andof Ecosystems Properties. Each of these books will give you insight into how God designed and created our world and the universe in which we live. No matter what grade you are in, third through eighth grade, you can use this book. 3RD–5tH GRàDe Read the lesson and then do the activity in thebox (the worksheets will be provided by your teacher). After you complete the activity, test your understanding by answering the questions in the box. Be sure to read the special features and do the final project. 6tH–8tH GRàDe Read the lesson and then do the activity in thebox. After you complete the activity, test your understanding by answering the questions in thebox. Also do the “Challenge” section in the box. is part of the lesson will challenge you to do more advanced activities and learn additional interest-ing information. Be sure to read the special features and do the final project. ere are also unit quizzes and a final test to take. roughout this book you will see special icons like the one to the right. ese icons tell you how the information in the lessons fit into the Seven C’s of History:Creation, Cor-ruption, Catastrophe, Confusion, Christ, Cross, Consummation. Your teacher will explain these to you. When you truly understand how God has designed everything in our universe to work together, and how He is working out His plans, then you will enjoy the world around you even more. So let’s get started!

The study of matter and molecules
lesson 1
What is chemistry?
WoRDs to know: chemistry matter chemist
hemistry may sound like a big word and a difficult subject to study, but it’s not.Chemistryis simply the study of matter, andmatterC is anything that has mass and takes up space. Some examples of matter are water, wood, air, food, paper, your pet skunk, or your little brother. So if you are interested in learning more about anything around you, then you are ready to learn about chemistry. Chemistsare scientists who study what things are made of, how they react to each other, and how they react to their environment.Chemistry is the study of the basic building blocks of life and the world. In chemistry you will learn about atoms and molecules. You will learn about how substances combine to make other substances. You will find out how a sub-stance changes form and you will discover that God created our world with such intricate designs that we may never fully understand how everything works. God has established laws that govern how chemicals react and how matter changes. Many of these laws seem mysterious because they happen on an atomic level. Although these changes cannot be seen with the naked eye, the results of these laws can be seen all around us. As you study atoms and molecules you will begin to understand these laws and appreciate the beauty of God’s design on the atomic level.

As you will learn in the upcoming lessons, some materials are very stable and do not change easily Other materials are very reactive and easily combine with other sub-stances to make a new substance PuRpose:To see a chemical reaction

MàteRIàls:baking soda, drinking cup, vinegar PRoceDuRe: Place teaspoon of baking soda in a drinking cup 2 Pour tablespoon of vinegar into the cup Now watch the reaction!
ConclusIon:Vinegar is an acid and baking soda is a base Acids and bases easily combine together to form salts In this reaction they also produce a gas Can you guess what that gas might be? It is carbon diox-ide
TaKiNg iT fUrThEr •Would you expect to see the same reac-tion each time you combine baking soda and vinegar?
