Отрывок из книги
WELCOME TO EXPERIMENTING WITH SCIENCE. I am so excited to guide you in your scientific journey as you test, explore, learn, have fun, and, yes, experiment. My goal is for you to experience the thrill of scientific discovery.
SO WHAT IS SCIENCE? Science is the study of the world around you – or even the world inside of you. In this book, you learn about many scientific disciplines, so get ready to make some reactions, trick your brain, harness magnetic forces, combine science and art, and more!
.....
You can then follow the instructions to start your project. While you’re working, make sure that you make observations of what you see, hear, feel, or even smell! I encourage you to make predictions of what you think will happen in your experiment. If you want to keep track of your predictions and data, go online to www.dummies.com/go/experimentingwithscience to find guidelines for making your own lab notebook.
When you complete your experiment, read about the science at the end of each project. This information helps you understand what you just observed. Some of these concepts are pretty crazy! See whether the explanations are consistent with your observations and experimental results.
