Experiments with soft drinks demonstrate the properties of liquids, gas, and acids.

Takes readers deep inside the secret world of corporate science, where powerful companies and allied academic scientists mold research to meet industry needs. The 1990s were tough times for the soda industry. In the United States, obesity rates were exploding. Public health critics pointed to sugary soda as a main culprit and advocated for soda taxes that might decrease the consumption of sweetened beverages—and threaten the revenues of the giant soda companies. Soda Science tells the story of how industry leader Coca-Cola mobilized allies in academia to create a soda-defense science that would protect profits by advocating exercise, not dietary restraint, as the priority solution to obesity, a view few experts accept. Anthropologist and science studies specialist Susan Greenhalgh discovers a hidden world of science-making—with distinctive organizations, social networks, knowledge-making practices, and ethical claims—dedicated to creating industry-friendly science and keeping it under wraps. By tracing the birth, maturation, death, and afterlife of the science they made, Greenhalgh shows how corporate science has managed to gain such a hold over our lives. Spanning twenty years, her investigation takes her from the US, where the science was made, to China, a key market for sugary soda. In the US, soda science was a critical force in the making of today’s society of step-counting, fitness-tracking, weight-obsessed citizens. In China, this distorted science has left its mark not just on national obesity policies but on the apparatus for managing chronic disease generally. By following the scientists and their ambitious schemes to make the world safe for Coke, Greenhalgh offers an account that is more global—and yet more human—than the story that dominates public understanding today. Coke’s research isn’t fake science, Greenhalgh argues; it was real science, conducted by real and eminent scientists, but distorted by its aim. Her gripping book raises crucial questions about conflicts of interest in scientific research, the funding behind familiar messages about health, and the cunning ways giant corporations come to shape our diets, lifestyles, and health to their own needs.

Sodas are astonishing products. Little more than flavored sugar-water, these drinks cost practically nothing to produce or buy, yet have turned their makers--principally Coca-Cola and PepsiCo--into a multibillion-dollar industry with global recognition, distribution, and political power. Billed as "refreshing," "tasty," "crisp," and "the real thing," sodas also happen to be so well established to contribute to poor dental hygiene, higher calorie intake, obesity, and type-2 diabetes that the first line of defense against any of these conditions is to simply stop drinking them. Habitually drinking large volumes of soda not only harms individual health, but also burdens societies with runaway healthcare costs. So how did products containing absurdly inexpensive ingredients become multibillion dollar industries and international brand icons, while also having a devastating impact on public health? In Soda Politics, the 2016 James Beard Award for Writing & Literature Winner, Dr. Marion Nestle answers this question by detailing all of the ways that the soft drink industry works overtime to make drinking soda as common and accepted as drinking water, for adults and children. Dr. Nestle, a renowned food and nutrition policy expert and public health advocate, shows how sodas are principally miracles of advertising; Coca-Cola and PepsiCo spend billions of dollars each year to promote their sale to children, minorities, and low-income populations, in developing as well as industrialized nations. And once they have stimulated that demand, they leave no stone unturned to protect profits. That includes lobbying to prevent any measures that would discourage soda sales, strategically donating money to health organizations and researchers who can make the science about sodas appear confusing, and engaging in Corporate Social Responsibility (CSR) activities to create goodwill and silence critics. Soda Politics follows the money trail wherever it leads, revealing how hard Big Soda works to sell as much of their products as possible to an increasingly obese world. But Soda Politics does more than just diagnose a problem--it encourages readers to help find solutions. From Berkeley to Mexico City and beyond, advocates are successfully countering the relentless marketing, promotion, and political protection of sugary drinks. And their actions are having an impact--for all of the hardball and softball tactics the soft drink industry employs to maintain the status quo, soda consumption has been flat or falling for years. Health advocacy campaigns are now the single greatest threat to soda companies' profits. Soda Politics provides readers with the tools they need to keep up pressure on Big Soda in order to build healthier and more sustainable food systems.

'How does it work? Why does it do that? What will happen if . . .?' Questions curious kids ask about everyday things from breathing to popcorn! Tracey Schofield's answer to these questions is a book filled with simple, fun science experiments and activities to help kids discover for themselves how the world works.

Remember: Science fair projects are due...NOW! It’s no secret that kids sometimes put off doing their assignments, especially if they get busy or don’t know where to begin. But with this compilation at hand, their science fair problems are over, because it’s full of super-quick ideas sure to wow the crowd and the judges. All the experiments use common, easy to find materials, and there’s valuable advice on creating an appealing presentation and writing an accompanying report. Construct a "Juice Rocket”; grow crystals along a piece of string; build a biosphere; and mummify an orange. And here’s one for the birds: an experiment to determine if our avian friends prefer one type of food over another. Every project is smart and fun!
