Chemistry is the study of the way materials are put together and their behavior under different conditions Matter makes up everything in the universe Chemists study matter to learn what it is made of and how it reacts The people who decide to work in the field of chemistry have a variety of careers to choose from Food chemists study the ingredients in what we eat doctors study biochemistry and the reactions that take place in the body and forensic chemists work with crime scene evidence All of these people have something in common they are constantly asking questions to learn even more about chemistry This book is a collection of science experiments about chemistry Why are ice pops softer than ice How does soap clean dirty dishes Can you test the hardness of water You will find the answers to these and many other questions by doing the experiments in this book How to Use This Book You will be rewarded with successful experiments if you read each experiment carefully follow the steps in order and do not substitute materials The following sections are included for all the experiments 4 Janice VanCleave’s Crazy Kooky and Quirky Chemistry Experiments IntroduCtIon
Purpose The basic goals for the experiment Materials A list of supplies you will need You will experience less frustration and more fun if you gather all the necessary materials for the experiments before you begin You lose your train of thought when you have to stop and search for supplies Procedure Step-by-step instructions on how to perform the experiment Follow each step very carefully never skip steps and do not add your own Safety is of the utmost importance and by reading the experiment before starting then following the instructions exactly you can feel confident that no unexpected results will occur Ask an adult to help you when you are working with anything sharp or hot If adult supervision is required it will be noted in the experiment Results An explanation stating exactly what is expected to happen This is an immediate learning tool If the expected results are achieved you will know that you did the experiment correctly If your results are not the same as described in the experiment carefully read the instructions and start over from the first step Why An explanation of why the results were achieved 5 Introduction
