Have you seen a dodo bird recently? Do you have mastodons playing in your back yard? Not likely-these species are both extinct, which means the entire population has died out. More than 99 percent of all species, or about 5 billion, have gone extinct since life first formed on Earth 4.5 billion years ago. Some of those species went extinct at the same time in an event know as a mass extinction.What type of event could cause such a massive die off? This is a question that scientists have asked for decades as they explore the causes of extinction. In Extinction: What Happened to the Dinosaurs, Mastodons, and Dodo Birds? readers ages 9 to 12 learn about the scientific investigative work necessary to answer these questions and find the culprit behind mass extinctions. Follow the scientists as they look at all potential reasons for extinction, including asteroid impacts, massive volcanic eruptions, excessive gases in the atmosphere, climate change, and more. Where do scientists find clues to help them answer their questions? In rocks-scientists travel the globe to excavate the evidence. They look for fossils that might tell them what lived before an extinction and what lived after. They also examine the chemical elements in rocks at the boundaries between geologic eras, as well as the structure of rocks. As they follow the evidence, the pieces of the puzzle come together to form a clearer picture of events that happened millions of years ago, whether it's an asteroid strike or a massive volcanic eruption.Extinction is not just a thing of the past. It is happening right now, at a higher rate than is typical. Because of this, there is debate about whether or not the presence of humans on Earth is having the same effect as an asteroid strike or a massive volcanic eruption. Are we currently experiencing the sixth mass extinction? And if so, what are the causes? Can we stop it? Extinction: What Happened to the Dinosaurs, Mastodons, and Dodo Birds? includes hands-on activities and critical thinking exercises to encourage readers to consider humans' role in the current extinction, what we can learn from past extinction events, and how they can be part of efforts to prevent extinction. Hands-on activities, a fun narrative style, interesting facts, species spotlights, and links to primary sources combine to bring the subject of extinction to life in a fun and engaging way.

Look around you--biodiversity is everywhere From the tallest tree to the smallest microbe, Earth is home to more than 1.5 million known species of plants, animals, fungi, bacteria, and microorganisms. And scientists estimate there could be millions, if not billions, more that have not yet been identified. Biodiversity: Explore the Diversity of Life on Earth with Science Activities for Kids introduces middle schoolers to the evolution of life on Earth, beginning with the first single-celled organisms that emerged 3.8 billion years ago to the complex, multi-celled organisms that exist today and make up the tree of life. Biodiversity is found everywhere on the planet--on land, in the water, and even in extreme environments such as ice and volcanoes. Biodiversity can also be discovered by looking through a microscope at tiny worlds of organisms that can't be seen with the human eye. There are whole microbiomes beneath our feet, in puddles, and even in our belly buttons All of this biodiversity on Earth helps keep the planet in balance. Biodiversity is also important to humans because it provides food, shelter, clothing, medicines, and more. However, the rates of biodiversity loss are increasing because of human activities. Climate change, pollution, habitat destruction, over-exploitation--these are all critical threats to biodiversity. There are, however, ways to slow or stop this loss through conservation and sustainable development. Biodiversity includes hands-on STEM activities and critical thinking exercises to encourage readers to consider the threat to biodiversity and figure out ways to be part of the solution. Fun facts, links to online primary sources and other supplemental material, and essential questions take readers on an exploration of the incredible biodiversity on Earth. Biodiversity is part of a set of four Build It Environmental Science books that explore the history and science of the planet and all that live on it through hands-on STEM activities and real-life environmental connections. Other titles in this series are Planet Earth, Garbage, and Biomes. Nomad Press books integrate content with participation.

Combining content with inquiry-based projects stimulates learning and makes it active and alive. Nomad's unique approach simultaneously grounds kids in factual knowledge while allowing them the space to be curious, creative, and critical thinkers.

An exciting book about the chain reaction world of Rube Goldberg for middle schoolers, including 25 engineering design projects that get middle schoolers applying the laws of physics to their own inventions as they learn the scientific principles behind the actions and reactions they create. Why use a simple hand motion to wipe your mouth when you can build a machine to do it for you? Toppling dominoes, rolling marbles, racing balloon cars, springing catapults, and whizzing zip-lines are all elements used to build Rube Goldberg machines in Crazy Contraptions: Build Machines that Swoop, Spin, Stack, and Swivel with Hands-On Engineering Activities. The book introduces kids ages 9-12 (and beyond ) to the wacky machines designed by Goldberg, which were based on complicated chain reactions used to accomplish very simple, sometimes ridiculous, tasks. - Through contraptions, the book discusses the basics of physics, including force, motion, and work. Each chapter introduces one of the six simple machines and how they can be used in Rube Goldberg contraptions--inclined planes, levers, wheels and axles, wedges, screws, and pulleys. - Kids are challenged to design, build, and evaluate dozens of increasingly complex contraptions that do things like unscrew a lid, turn the page of a book, and pop a balloon. - Projects use materials already in most homes--reimagining and repurposing everyday items, as well as mining the recycling - Contraption hints, essential questions, short sidebars, and links to online primary resources help readers learn the basics of force, work, motion, and simple machines, while exploring their creativity as they design and build their own crazy contraptions. About the Build It Engineering set and Nomad Press Crazy Contraptions is part of a set of two Build It Engineering books that explore the engineering technology behind our daily lives. The other titles in this series is Bots Robotic Engineering with Hands-On Makerspace Activities. Nomad Press books in the Build It series integrate content with participation.
