We moved on to our next topic today: tides. I gave a lecture to students, using the PowerPoint posted below, that covered quite a bit of ground. We discussed what tides are, how they are caused by the moon’s gravity, why they switch roughly every six hours, and how the sun influences things too. We also talked about a strange example, the Bay of Fundy, where tides can vary by as much ass 55 feet! Then we finished off with a quick engineering competition. The goal? Protect Marshfield from our rising tides.

to see state-specific standards (only available in the US).
Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. Emphasis for the model is on gravity as the force that holds together the solar system and Milky Way galaxy and controls orbital motions within them. Examples of models can be physical (such as the analogy of distance along a football field or computer visualizations of elliptical orbits) or conceptual (such as mathematical proportions relative to the size of familiar objects such as students’ school or state). Assessment does not include Kepler’s Laws of orbital motion or the apparent retrograde motion of the planets as viewed from Earth.
Analyze and interpret data to determine scale properties of objects in the solar system. Emphasis is on the analysis of data from Earth-based instruments, space-based telescopes, and spacecraft to determine similarities and differences among solar system objects. Examples of scale properties include the sizes of an object’s layers (such as crust and atmosphere), surface features (such as volcanoes), and orbital radius. Examples of data include statistical information, drawings and photographs, and models. Assessment does not include recalling facts about properties of the planets and other solar system bodies.
Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons. Examples of models can be physical, graphical, or conceptual.
