Humans live longer now than they ever have in their more than three hundred thousand years of existence on earth. And most (if not all) of the advances that have permitted the human lifespan to double have happened in living memory. Extra Life looks at vaccines, seat belts, pesticides, and more, and how each of our scientific advancements have prolonged human life.

Sure, almost all kids know Benjamin Franklin as one of America's Founding Fathers, a man with a hand in both the Declaration of Independence and the US Constitution. And they may even have some vague idea that he once flew a kite during a lightning storm. What Kathleen Krull sets out to do in this very different biography is show Ben Franklin as the natural philosopher (the term for scientists back in the 1700s), whose experiments led to important discoveries about the nature of electricity - including his famous demonstration that electricity and lightning were one and the same.

All his life, Charles Darwin hated controversy. Yet he takes his place among the Giants of Science for what remains an immensely controversial subject: the theory of evolution. Darwin began piecing together his explanation for how all living things change or adapt during his five-year voyage on the HMS Beagle. But it took him 20 years to go public, for fear of the backlash his theory would cause.

Ernest Everett Just was not like other scientists of his time. He saw the whole, where others saw only parts. He noticed details others failed to see. He persisted in his research despite the discrimination and limitations imposed on him as an African American. His keen observations of sea creatures revealed new insights about egg cells and the origins of life.

The book Scripts and Songs on Science and Math 2 is a collection for school-age students that covers the variety of topics in science with the help of musical theatrical plays and material. They were created to help learn science by singing. It includes scripts about the creation of the periodic table of the chemical elements by Mendeleyev, the invention of the microscope by A. Leeuwenhoek in biology, the discovery of Newton’s Laws, developing Algebra, and other science-math topics. The songs and scripts speak to both the mind and heart.

A lively exploration into the life of Charles Darwin, One Beetle Too Many recounts both Darwin’s childhood and his time on the Beagle as a naturalist. This adventurous tale explores Darwin’s discoveries in geology, paleontology, and animal anatomy that led to his famous theory of evolution.

From the team that created the ALA Notable Book The Cod's Tale comes the fascinating history of salt, which has been the object of wars and revolutions and is vital for life. Based on Mark Kurlansky's critically acclaimed best seller Salt: A World History, this handsome picture book explores every aspect of salt: The many ways it's gathered from the Earth and sea; how ancient emperors in China, Egypt, and Rome used it to keep their subjects happy; why salt was key to the Age of Exploration; what salt meant to the American Revolution; and even how the search for salt eventually led to oil.

Katherine knew it was wrong that African Americans didn't have the same rights as others - as wrong as 5+5=12. She knew it was wrong that people thought women could only be teachers or nurses - as wrong as 10-5=3. And she proved everyone wrong by zooming ahead of her classmates, starting college at 15, and eventually joining NASA, where her calculations helped pioneer America's first manned flight into space, its first manned orbit of Earth, and the world's first trip to the moon!

Did you know that it’s believed Galileo was scolded by the Roman Inquisition for sassing his mom? That Isaac Newton loved to examine soap bubbles? That Albert Einstein loved to collect joke books, and that geneticist Barbara McClintock wore a Groucho Marx disguise in public? With juicy tidbits about everything from favorite foods to first loves, the subjects of Kathleen Krull and Kathryn Hewitt’s Lives of the Scientists: Experiments, Explosions (and What the Neighbors Thought) are revealed as creative, bold, sometimes eccentric - and anything but dull.

In 1752, the sky in Philadelphia, Pennsylvania, darkened. A thunderstorm was coming. Benjamin Franklin was ready to perform an experiment. He wanted to show the electrical nature of lightning. His experiment was a success, but he didn’t discover electricity that day. Myths about Franklin and his experiment have been told for years. Discover what’s real and what’s fiction through infographics, primary sources, and expertly leveled text.

Thomas Edison was a famous American inventor in the late 1800s. His work with light bulbs got a lot of attention. Over time, many stories were told about this work, including that he invented the light bulb. But this isn’t true! Discover what’s real and what’s fiction.

Solid wax is somehow changed into light and heat. But how? Travel back in time to December 28, 1848 in London, England to one of the most famous juvenile science Christmas lectures at the Royal Institution. British scientist Michael Faraday (1791-1867) encouraged kids to carefully observe a candle and to try to figure out how it burned. Known as one of the best science experimenters ever, Faraday’s passion was always to answer the basic questions of science: “What is the cause? Why does it occur?”

Today, everyone is familiar with Neil Armstrong's famous words as he first set foot on the moon: "one small step for man; one giant leap for mankind." But America's journey to the moon was anything but simple. In 1957, the Soviet Union launched Sputnik, the world's first satellite, into orbit; later that year, America's first attempt was such a failure that the media nicknamed it "Kaputnik." Still, we didn't give up. With each failure, we gleaned valuable information about what went wrong, and how to avoid it in the future. So we tried again. And again. And each time we failed, we failed a little bit better.

Inspired by Nathaniel Rich’s Losing Earth: A Recent History, the acclaimed book that grew out of an August 2018 issue of the New York Times Magazine solely dedicated to it, Saving Earth tells the human story of the climate-change conversation from the recent past into the present day. It wrestles with the long shadow of our failures, what might be ahead for today’s generation, and crucial questions of how we understand the world we live in—and how we can work together to change the outlook for the better.

The Earth is definitely getting warmer. There's no argument about that, but who, or what, is the cause? While the vast majority of scientists who study the environment agree that humans play a large part in climate change, there is a counterargument. Author Gail Herman presents both sides of the debate in this fact-based, fair-minded, and well-researched book that looks at the subject from many perspectives, including scientific, social, and political.

On 24th November 1859, Charles Darwin’s On the Origin of Species was first published, selling out almost immediately. Describing the now well known theory that humans evolved through a process called natural selection, it cemented Darwin as one of the greatest biologists of all time. However, he couldn’t have done it without the support and advice from those who believed in him. None more so than Joseph Hooker. Hooker, too, had his own adventures and made his own discoveries—many of which not only aided Darwin, but went on to change what the world knew about plants.

In 1915, British astronomer Arthur Stanley Eddington was fascinated with Einstein's new theory of general relativity. The theory talks about how forces push and pull objects in space. Einstein said that the sun's gravity could pull and bend light.

Is planet Earth flat? Is California an island? Can you mix other metals to make gold? At one time science supported wild notions like these! But later studies proved these ideas were nonsense. Discover science's biggest mistakes and oddest assumptions about geology and ecology, and see how scientific thought changed over time.

In 1841, a quiet, curious boy who stuttered when nervous committed to becoming a surgeon—a profession then more feared than respected. Through study, persistence, and careful research, Joseph Lister proved that unsanitary conditions contribute to infections. Despite others scoffing at his ideas, Lister slowly changed the way all surgeons work, saving countless lives.

This is the exciting story of a soil scientist confronting politicians to encourage them to pass a law to protect the land, the soil. When the US Congress passed a law establishing the Soil Conservation Service, it was the first government agency in the world dedicated to protecting the land, to protecting the Earth.
