How to Be a Scientist Scientists learn about the world around us by doing experiments. This book is full of experiments you can do in your bathroom. You won’t need any special equipment. You’ll probably have everything you’ll need at home already. Remember to ask a grown-up before using anything. Before you begin, always read through the whole experiment to make sure you have everything you will need.
BE SAFE! Never play with the medicines or cleaning products you might have in your bathroom.
