CHAPTER 1 INTRODUCTION One might think that chemists are a bunch of boring scientists who wear lab coats and look at beakers all day, but did you know that many toys you play with are made using chemistry? Some of your favorite toys like Gak, Slime and Silly Putty started out as chemistry experiments. In fact, some of your favorite toys may have been invented by chemists who work for toy companies like: Crayola, Play-Doh or Mattell. Chemistry is the study of matter, and how different elements of matter interact. There are many different kids of matter, which need to be described using the concept of properties. Toys like silly putty are unique because of they have distinct properties that are different from the properties of other types of matter. There are two different kinds of properties, chemical properties and physical properties. Chemical properties are qualities that can be observed during a chemical reaction, like when vinegar reacts with baking soda. Physical properties are qualities that can be observed during physical change in the absence of a chemical reaction, like the melting of an ice cube. Physical properties can be used to describe the state of a chemical, which can be a solid, liquid or a gas. The physical and chemical properties of Silly Putty are what make it so much fun because it is a polymer that is stretchy and bouncy! Scientists use properties to describe all of the unique qualities of a chemical or a mixture of chemicals. To do this they use descriptive language, or words that are used to describe objects. Some descriptive words used to describe a chemical might be: hot, cold, squishy, hard, soft, crystalline, granular,
