Is there ice on Mercury? Why isn't Pluto a planet? As viewed by the modern astronomer, the Solar System includes more than 100 diverse worlds interacting as a dynamic system. This online course for K-12 in-service teachers focuses on fundamental questions driving NASA's exploration of the Solar System: How did it form? What's in it? How is it arranged? What does the study of other worlds (planets, moons, asteroids, and comets) teach us about our own? How do we learn about other worlds? How are these worlds similar and different?

Can quantum mechanics be made SIMPLE? What lies behind wave functions and Schrödinger’s wave equation? How is the microscopic world really put together? Can one explore the peculiar quantum world without resorting to complicated mathematical treatment? In his popular little book, QED, The Strange Theory of Light and Matter, Richard Feynman reduces the rules of quantum mechanics to a simple command for the electron and the photon: Explore all paths. In 1948 Feynman proved that this command leads to all the same results as the usual quantum wave mechanics.

What do we mean by "curved spacetime"? As you freely fall toward a black hole, how long does it take to reach the event horizon according to your watch? Can your friend at a safe distance actually see you cross the horizon? What happens at the horizon? Can you receive messages and packages from your friend on the outside? Can you send messages to your friend on the outside? How quickly will it be over at the central crunch point? You can answer these questions for yourself with some math, starting from a simple formula, the "metric," for the black hole.

Astronomy has long been a subject that captures the imagination of young students and provides a framework for teaching many kinds of science. This course, specially designed for practicing science teachers at the middle and high school levels, serves as a survey of topics in astronomy, with special emphasis on the latest advances. The topics are closely aligned with the concepts emphasized in the NRC National Science Education Standards. Our textbook is a very complete, very up-to-date, very readable source that teachers will want to keep as a reference.

This course describes the workings of the world around us. The everyday: how a ball moves when it is thrown, the forces you feel on a roller-coaster, what happens when you turn on a light switch; and the esoteric: time and space from the perspective of Einstein's relativity, the basic structure of atoms and nuclei. The course is mostly at the conceptual level, with some simple algebraic problem solving.

This course approaches Einstein's theory of Special Relativity with a geometric perspective instead of through the Lorentz Transformation used in most introductory texts. There are two advantages. First, since geometry is the foundation for General Relativity (GR), this approach affords a seamless transition for students taking GR in the spring. Secondly, it leads to a more useful method for problem-solving in SR (Special Relativity) and with a modified Pythagorean Theorem and spacetime diagrams we can answer any question with confidence.

The objective of this course is to introduce educators and others to the complex world of Microbial Ecology. We will achieve this by exploring a wide range of topics within this subject area including the ecology of microorganisms in relation to nutrition, growth, metabolism, biogeochemical cycling, natural environments, and microbial interactions. You will be encouraged to dive in and investigate the various topics and make them relevant within your life, own classroom or work situation.

Appreciating the complexity of the biosphere involves consideration of its microbial constituents. Environmental impacts and global climate change often show early evidence in its smallest inhabitants. This course is designed for science educators, but will provide all interested participants with the fundamentals of environmental and applied microbiology.

The goal of this course is to provide science educators and others with the fundamentals of microbiology. This information will allow participants to expand their knowledge base and enhance teaching activities in this subject. Teachers will gain an appreciation of microbiology through readings, web searches, active participation in discussions, assignments, and an experiment on microorganisms. They will also learn that microbiology can be applied in daily life, in biotechnology, and in studying complex issues such as our dependence on microbes.
