Curricula | inquiryHub: Research-based Curricula Supporting Next Generation Science | U... - 0 views

  •  
    inquiryHub high school and middle school curricula are aligned to the Framework and guided by the Next Generation Science Standards (NGSS). Using research-based approaches to teaching science in a deeply digital environment, students contribute resources, observations, data, and analyses to solve larger scientific problems.  inquiryHub curricula are designed to go beyond traditional science content. By focusing on phenomena relevant to students' lives and communities, the coursesprovides opportunities to authentically engage with science and engineering practices.

6 Things Your Body Does That Science Still Can't Explain - YouTube - 0 views

  •  
    8:13 One of the greatest mysteries is not whether ghosts are real or if there's alien life. The mystery is us. Here are some simple things our body does that science still can't figure out.

  •  
    Throughout the last few decades, diseases that spill over from animals to humans have been on the rise. What's behind their increase, and can we do anything to combat these dangerous foes? Join scientists as they investigate the rise of spillover viruses like Zika, Ebola and Nipah, and learn what science can do to anticipate and prevent epidemics around the world.

Cauldron of Democracy - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study explores the controversy surrounding Yellowstone bison (Bison bison) and the relationship between wildlife management and pluralist democracy. In the late 1960s Yellowstone National Park suspended the policy of strictly managing bison by culling in favor of "natural processes" management. This led to dramatic herd growth and to bison exiting the park in winter in search of forage. Montana cattle ranchers reacted angrily for fear that the animals would infect their cattle with brucellosis. Since 2000, several government agencies have administered the Interagency Bison Management Plan, which uses culling to manage the population at around 3,000 head. The resumption of culling has upset environmental groups, while the recently approved expansion of bison habitat beyond park boundaries continues to upset ranchers.  The ongoing political battle between ranchers, environmentalists, Native American tribes and government agencies shows how difficult it can be to balance legislative mandates, ecological values, and conflicting public demands. The case study may be employed in a variety of courses, including American Government, Public Policy, Interest Groups, Environmental Studies and National Parks.

DNA from 4,500-year-old Ethiopian reveals surprise about ancestry of Africans - LA Times - 0 views

  •  
    DNA from a man who lived in Ethiopia about 4,500 years ago is prompting scientists to rethink the history of human migration in Africa. Until now, the conventional wisdom had been that the first groups of modern humans left Africa roughly 70,000 years ago, stopping in the Middle East en route to Europe, Asia and beyond. Then about 3,000 years ago, a group of farmers from the Middle East and present-day Turkey came back to the Horn of Africa (probably bringing crops like wheat, barley and lentils with them).

  •  
    The cellular life cycle, also called the cell cycle, includes many processes necessary for successful self-replication. Beyond carrying out the tasks of routine metabolism, the cell must duplicate its components - most importantly, its genome - so that it can physically split into two complete daughter cells. The cell must also pass through a series of checkpoints that ensure conditions are favorable for division.
