EARTH: THE BIG PICTURE

Were you fascinated by the recent eclipse and aurora borealis events? Ever wonder why we have seasons, or why there are spring tides in the summer, autumn and winter? Why do we have leap years and leap seconds? Why does earth have oceans? Using lectures, videos, Q&A and discussion we will answer these questions and more as we take a “big picture” look at our planet. No previous science experience is necessary, just curiosity about our planet and a willingness to participate in Lynn’s Zoom polls. Over the course of four weeks, we will look at Earth in the solar system, the relationship between Earth and the moon, the Earth’s gravitation and magnetic fields, and why the Earth has water and oceans. Relevant and interesting links and handouts will be provided throughout the class.
