Science is powerful: with it, we're finding cures for cancer, building supercomputers and cell phones, and keeping people in space. This is a quick overview of how science works (i.e.: the scientific method).
There is also a brief look at the kinds of maps earth scientists use. Some might be a review, but the part on topographic maps is probably new for most of you.
Our sun is a pretty ordinary star; just one of billions in the universe. In this course, we'll look at our moon, the sun, earth, the other planets and other common neighbors in our solar neighborhood.
The universe is everything: all the billions of galaxies, each with billions of stars, and all the dust, gas, and empty space in between. In this course, you'll get an overview of everything: how it began, and how it may end.
We'll also look at human efforts to explore space so far.
Oceans comprise 71% of earth's surface, and 97% of earth's water. It can be an enormous energy and food resource, if we use it wisely.
We live miles deep in an ocean of air. This course will study our atmosphere, and how it protects us.
In the next course, we'll see how it makes our weather.
The first scientist to suggest that continents move was ridiculed; now we know it's true. The earth's crust floats around on a semi-liquid mantle, and that causes most earthquakes and volcanoes. In this course, we'll see how that and other geologic forces shape and re-shape the solid earth.
