Opis

With concern for the environment increasing, ecologically sound projects are more in demand. Providing a variety of experiments, both traditional and unique to this book, this study aims to help children to develop an understanding of the growth and life of plants. The projects are organized by topic and include studies on phototropism, aeration and fertilizers, as well as more unusual experiments on hydroponics and chemical growth regulators. All of these experiments can be conducted at home, with no special equipment required.
