This book examines bacteria that are found in virtually every environmentincluding those that are characterized by extreme heat, cold, and depthand, of course, bacteria that are found inside our bodies. Case studies examine the development of new vaccines against bacterial diseases and the use of bacteria to help fight pollution.
Taking information out of one living thing and putting it into another is what genetic engineering is all about. How do scientists do it? Why do they do it? What are the results of their experiments with these amazing genetic materials? Through colorful photos, diagrams, and stories, you can understand the basics of genetic engineering. You can even see what the future of this science holds, from Enviropigs to designer pets!
From a stalk of corn to a pine tree, every plant is made of plant cells. What material is in these cells? How do they hold together? How do growers use their knowledge of cell growth to create new plants? What's next in plant science? You can see the hidden secrets of cell life in the fascinating photos, diagrams, and text inside.
Who are we, really? We share traits with our parents, but our genetic makeup is unique. Each one of us is a one-and-only creation. Through colorful photos, diagrams, and text, you can learn about genetics. See how the simple pea plant taught us the rules of inheritance. Find out how our genetic code is unlocking the mystery of where we came from and our connections with all living things.
Everywhere you go, there are things to explore in nature. What do you think you'll see?
How Is Soil Made introduces children to the concepts of organic and inorganic parts of soil, the nutrient cycles of plants, and decomposition. Complex processes such as weathering, erosion, and deposition are also made easy to understand.
Young readers will be astounded by the tiny organisms that live in soil, their ecological roles, and how they adapt to living there. Children will learn the value of even the smallest bacteria and be amazed by the impact that soil degradation has on an entire ecosystem.
