101 science experiments.

Description

One hundred and one experiments that answer student's questions concerning basic scientific concepts. Illa Podendorf is a science teacher who encourages children to work on their own and to investigate and solve problems as scientists do. Doing experiments, like the ones outlined in this book not only helps children develop better concepts but, incidentally, improves reading skill and the capacity to follow directions intelligently. Thus children become equipped to explore the ever-expanding world of knowledge to which science leads. By doing the experiments in this book, children see or hear or otherwise observe what happens in certain situations. When they learn what happens in a very small part of the universe they get understandings that help explain events in a larger universe. Doing these experiments is fun. This is a good reason to do them for children can learn while having fun. But there is a more basic reason. Through experiments children get first-hand knowledge that certain things do indeed take place. The knowledge gained through experimenting, supplemented with other types of learning, enables children to build concepts with which to interpret the world around them. Paul E.

First Sentence

Most people like to experiment—to try something which they have never tried before—and see what happens. Scientists do a great deal of experimenting. They experiment to find the right answers to questions and to find ways of making new things. When scientists do an experiment, they look, listen, read and make records. They are almost sure to plan an experiment if an experiment is the best way to find an answer to a question or to something which they wish to know. Experiments are important but scientists also use other ways of getting accurate information. They may watch growing plants or animals for a period of time and make careful records of what happens. They may collect and look at things. They may listen to different sounds. They read what other people have written about the subject that interests them. Scientists may use several ways to find answers to their many questions. When a scientist does an experiment, there are certain things which he is almost sure to do. He first decides what his question is—what it is that he wants to find out. Then he decides upon a plan for doing the experiment and gathers the materials which he will need. As he thinks about the experiment, he will most likely form an opinion about what will happen. Then he will do the experiment. He will watch everything that happens and, if it is necessary, he will make a record of it. He will note whether his opinion was correct or not. He may need to repeat the experiment several times before he can be sure of the answer to his question.
