Look at Nature's Cycles

As Earth moves around the sun, the seasons on Earth change. The movement of the moon affects the tides in Earth's oceans. What happens in space has an influence on our lives. In this book, readers explore the cycles in the space that most affect us and the space science taught in upper elementary science classes. Accessible language and simple explanations make this the perfect introduction to Earth's cycles for readers struggling with traditional textbooks. Diagrams of each cycle provide a great review of each cycle as well as another way to understand each concept.

Understanding the water cycle provides a solid foundation for comprehending weather and even some climate change topics. It's also a part of many elementary science curricula and important for everyone to understand, even struggling readers. This book aims to bring all learners up to speed on the basics of the water cycle, from precipitation to evaporation, and includes fact boxes to provide more vocabulary and concept context. Diagrams and full-color photographs complement the low-level text and simply stated science information.

Life on Earth depends on carbon. In fact, about 18.5 percent of a human body's mass is carbon. How carbon is taking in and given off through animals' breathing, the burning of fossil fuels, and more can be shown in the model known as the carbon cycle. Though this concept can be confusing, all readers have a chance to understand this concept through the text and simple diagrams in this book. Both struggling readers and those looking for review can find the most important components and vocabulary of the carbon cycle in low-level, accessible text.

There are many steps in the nitrogen cycle that include difficult concepts and words: denitrification, prokaryotes, ammonia, and more. With the help of this understandable book, even struggling readers will grasp this cycle of nature. Low-level language, fact boxes, and an extended glossary provide readers with essential vocabulary explanations that allow them to further understand each step of the cycle. Full-color diagrams aid readers' comprehension as they move through the cycle from start to finish, and then around again.

The movement of oxygen from product of photosynthesis, through the human system, water, and Earth's atmosphere is a scientific model called the oxygen cycle. And it's essential for life on Earth to continue. Through accessible language and full-color diagrams and photographs, this book explains an important natural cycle to readers of all levels, particularly those struggling to understand a standard text book. Fact boxes and an extended glossary allow for the inclusion of the most important science vocabulary so all readers have the ability to understand, speak, and write about the topic.

All organisms in an ecosystem are connected. Some are predator, some are prey, and others are just there to help decomposition. What's more, food chains and food webs are a crucial part of the Earth and life science curricula. Written for struggling upper elementary readers, the main content highlights the most important points, as well as the essential vocabulary relating to food chains and webs. Full-color diagrams aid readers' comprehension.
