Deserts are amazing ecosystems and ecosystems are an intrigal part of STEM. Deserts may have very little water, but they are home to many plants and animals. Young children are introduced to one desert food chain and are encouraged to learn more and draw a food chain of their own. Also see Food Chains In The Forest to help round out this topic.
Most of us use water all day, every day, without thinking about it. But how does it get to our homes? From the pitter patter of raindrops to the whoosh of water from the shower, this book follows the journey from the source to the resource. Water is one of the most vital natural resources for humans, and we use it in abundance for more than just drinking water. It is used in household chores, leisure activities, and in work and industry. Readers will learn about where water comes from and the water cycle, as well as how water is stored, treated, and pumped around the country and into our homes. Real-world examples consider the environmental impact of our water use and how we can reduce consumption in our daily lives, and how many people live in places around the world that do not have a reliable water supply and rely on local methods to clean water that is in short supply.
Most of us eat three full meals a day, but where does the food that reaches our plates, stocks our fridges, and fills the supermarket shelves come from? This informative book shows how methods of growing, using, and delivering food - one of the most vital resources to humans - have developed and changed throughout time. Find out about the history of food production and present-day methods of farming. Learn about food delivery, the processes used to preserve and store food to make it last longer, how different foods are prepared, and food safety. Real-world examples encourage discussion of the ethics and worldwide impact of the production, distribution, and consumption of this global resource.
This timely book looks at the world's production of oil and our dependence on this natural resource. The majority of today's forms of transportation run on fuel that comes from oil, and hundreds of thousands of the items we use every day come from oil or oil-based products. Readers will find out about the origins of oil and its first use in industry, and learn how it is found, mined, and processed into many different products that are used all over the world. Real-world examples also consider the environmental and human disasters related to oil, encouraging discussion of the ethics and worldwide impact of the production, distribution, and consumption of this global resource. Possible alternatives to using oil are also discussed now that this important, non-renewable natural resource is running out.
What happens when you flip a light switch or press the power button on the TV? Electricity flows to the device and it turns on. Most of us use electrical gadgets all day, every day, without thinking about it. This book follows the journey from source to resource of solar power, one of the most exciting forms of renewable energy today. Readers will learn how electricity is made and collected directly from the sun and how it reaches us to power our modern world. Other sources of energy are also examined, as well as how grids work to move electricity across land and sea, and how it is fed into our homes. Real-world examples look at solar farms, solar furnaces, solar towers, and even solar transportation. With the world's nonrenewable resources such as oil running out, the advantages and disadvantages of solar power as a renewable alternative are discussed.
Imagine your family had to choose between sending you to school or having enough food to eat. This book tells how William Kamkwamba was forced to drop out of his school in Wimbe, Malawi, when a famine struck his village and his family, who relied on farming, could no longer afford his tuition fee. Instead of giving up on his education, William visited his local library often. It was here that he read a book about wind power. At the age of 14, William used what he learned from the book to build a windmill that brought power to his family’s home. He has since built his village’s first drinking water pump. William’s ingenuity, perseverance, and initiative are an inspiration to many people around the world.
This exciting book explains how the shape of Earth can change with the sudden movement of Earth's crust or when molten rock explodes out of an opening in Earth's surface. Young readers will be fascinated to discover how volcanoes form - destroying the landscape and creating new landforms at the same time. They will also learn about tectonic plates and fault lines, the damage earthquakes can cause, and how to stay safe when an earthquake happens.
This fascinating book explains how the shape of Earth is changed by weathering and erosion - the breaking down of rocks and minerals which are then carried from one place to another by water, ice, wind, and gravity. It is this movement that carves out valleys, causes trees to topple over, and creates or destroys good farmland. Examples of changes to landforms help show young readers the effects of weathering and erosion, which can happen quickly or sometimes take centuries!
Earth's surface is constantly being changed by heat, water, ice, salt, plants, and animals. Sometimes the changes are destructive to human activities such as farming and the building of structures. This interesting title shows the different ways people try to stop or reduce this change in the land. Examples feature such structures as dikes to hold back water and windbreaks, and adding shrubs, grass, and trees to an area of land to prevent erosion. Teacher’s guide available.
This informative book explains how Earth is covered by landforms and bodies of water, all of which change shape over time. Interesting images feature landforms such as mountains, valleys, and sand dunes, as well as waterways such as oceans, rivers, and ponds. Children will learn how they develop and why they change.

One evening at dusk a wind current carries a lone firefly out over the sea. Glancing down into the water, the insect is mesmerized by the glowing bioluminescence, mistaking it for other fireflies. Seeking company, the firefly plunges into the waves. Luckily, there are human bystanders who can lend a hand. Based on an event witnessed by nature writer and ecologist Rachel Carson (The Sea Around Us and Silent Spring) where a firefly attempts to join its "family" in the ocean, this lyrical story written in verse perfectly illustrates the wonder and delight the natural world offers those who pay close enough attention. Back matter includes science facts about fireflies and bioluminescence, as well as information about Carson's life.
For decades, as the monarch butterflies swooped through every year like clockwork, people from Canada to the United States to Mexico wondered, "Where do they go?" In 1976 the world learned the answer: after migrating thousands of miles, the monarchs roost by the millions in an oyamel grove in Central Mexico's mountains. But who solved this mystery? Was it the scientist or the American adventurer? The citizen scientists or the teacher or his students? Winged Wonders shows that the mystery could only be solved when they all worked as a team--and reminds readers that there's another monarch mystery today, one that we all must work together to solve.
