Every year in Namibia, about two thousand zebras suddenly disappear from their grazing area along the Chobe River. Months later, the herd returns. Where do they go? And why? Thanks to satellite-tracking collars, scientists were able to solve the mystery, but several questions remain. Award-winning science author Sandra Markle reveals the process scientists used to study the zebras, and she also delves into the science of migration, exploring how animals know where to go, how to get there, and when to leave.
In the history of life on this planet, 99.9 percent of all species have gone extinct. But a few have survived almost unchanged. Author Rebecca E. Hirsch introduces readers to six living fossils, including the chambered nautilus, the horseshoe crab with its sticky blue blood, and venomous platypuses that sting, as well as a comprehensive explanation of evolution and extinction for readers who may not be familiar with the terms yet. Readers will also discover a a spectacular timeline of the history of animal life on Earth. Dive into the stories of these incredible animals and find out how they help scientists piece together evolutionary history.
Apples, blueberries, peppers, cucumbers, coffee, and vanilla. Do you like to eat and drink? Then you might want to thank a bee. Bees pollinate 75 percent of the fruits, vegetables, and nuts grown in the United States. Around the world, bees pollinate $24 billion worth of crops each year. Without bees, humans would face a drastically reduced diet. We need bees to grow the foods that keep us healthy. But numbers of bees are falling, and that has scientists alarmed. What's causing the decline? Diseases, pesticides, climate change, and loss of habitat are all threatening bee populations. Some bee species teeter on the brink of extinction. Learn about the many bee species on Earth—their nests, their colonies, their life cycles, and their vital connection to flowering plants. Most importantly, find out how you can help these important pollinators.
Burmese pythons are native to Southeast Asia, so when one showed up dead along the side of a Florida highway in 1979, scientists wondered where it came from. No one knew the snakes had launched a full-scale invasion. Pet pythons that escaped or were released by their owners started breeding in the wild, and these enormous predators began eating every animal in their path. Today a group of scientists at the Conservancy of Southwest Florida is tracking Burmese pythons to find ways to stop their spread. Page Plus links lead to video clips and photos of the scientists working in the field. Delve into the science of pythons and their role as invasive predators.

Containing 97 percent of Earth's water supply, the ocean plays a huge role in regulating global temperatures, supporting plant and animal life, and contributing to the livelihoods of millions of people. But in spite of all this, the ocean remains drastically unexplored, and the details of its impact on human lives aren't fully understood. Scientists from around the world are realizing that to address issues plaguing the ocean, such as dead zones, coral bleaching, and climate change, we need to better understand this incredible, unique feature of our planet. With a range of impressive, cutting-edge technologies at their disposal, oceanographers have set out to measure, sample, and analyze at every turn. Every day, mysteries about the ocean are being solved, and every day, new questions come to light. The more scientists learn, the better they are able to answer these new questions. What lies in the deep? And who is at the forefront of these exciting discoveries? The scientists and research included in this book shed light on the most pressing issues currently facing oceanographers and point us in the right direction to solving these challenges.
Snowmen droop / Cardinals swoop, Rabbits bounce / Foxes pounce In the early days of spring when the snow begins to melt, plants and animals stir to life.

On April 22, 1970, an estimated twenty million people held in a teach-in to show their support for environmental protections. This new celebration, Earth Day, brought together previously fragmented issues under the same banner. It was the largest nationwide event ever, and lawmakers took notice. But one day didn't change everything. Fifty years after the first Earth Day, climate change remains a dire concern. The divide between political parties continues to widen, and environmental policy has become an increasingly partisan issue. The spread of disinformation has also made climate change a debatable idea, rather than scientific fact. A new generation of advocates continue the fight to make environmental policy a top priority for the United States and for nations around the globe
