COSMOS Episode 2: Some of the Things that Molecules Do (2014) continues the exploration of our human origins through the eyes of science. This episode explains the origins of species by means of natural and artificial selection. It also looks at the origin and evolution of life from the microscopic to macroscopic scale. Neil DeGrasse Tysons explores the possibility of life on other worlds, even in our own solar system!
COSMOS Episode 6: Deeper, Deeper, Deeper Still (2014) relates our understanding (and subsequent interpretation) of reality to our rather limited perspectives of scale. Neil DeGrasse Tyson reveals reality from a subatomic scale to the entire known universe. He tells the story of evolutionary processes that work on different levels of size and scale. Tyson links the deep relationship the atoms we are made from with their creation from the ashes of stars that exploded before the sun was even formed.
COSMOS Episode 9: The Lost Worlds of Planet Earth (2014) teaches us how to read the autobiography of the earth. Neil DeGrasse Tyson explains that to read this book, we must understand the relationship between the atoms, elements, geophysics, biochemistry, and time. This episode is great for a biology, geology, chemistry, or an environmental science class, since it delves deep into the relationship between the biological evolution of life and the geologic and environmental conditions necessary over many time periods.
COSMOS Episode 12: The World Set Free (2014) is a great environmental wake-up call for the citizens of earth. Neil DeGrasse Tyson effectively demonstrates the parallels of the runaway greenhouse effect that occurred on Venus (and the hellish conditions it produced) and what we are currently doing to the earth. Tyson presents solid, scientific evidence to support his claims. But does humanity have the will to take the steps necessary before it is too late?
COSMOS Episode 13: Unafraid of the Dark (2014) wraps-up the COSMOS series by exploring the constant fight between intelligence, compassion, and understanding, versus the darker side of the human condition, manifested by fear, ignorance, and brutality. Neil DeGrasse Tyson connects the path to salvation through the application of the principles of science to facilitate reasoning and a societal enlightenment. In the end, any journey of societal growth starts with the individual. Individual choices, based on sound reasoning and rational thought, help to form a grass-roots movement, whereby ignorance and fear slowly start to give way and lose their appeal. This is the main message the COSMOS series endeavors to relay. This final episode delivers that message right on-time.
Adam and Jamie are examining the myth that wrecking balls can be used to make a Newtonâ€™s Cradle. Grant, Kari, and Tory are also testing to see whether a bird perched on a teetering car can cause it to fall over the edge. Scientific concepts include energy transfer, Newtonâ€™s Third Law, equal and opposite reactions, energy efficiency, surface deformation, elastic and inelastic collisions, potential and kinetic energy, pendulum motion, trophic levels, biology, predator prey relationships, energy flow, food webs, type 1 lever, fulcrum, pivot points, lever arms, and torque.
