Knowledge: meeting the learning goals and expectations. Complex Knowledge: demonstrations of learning that go aboveand above and beyond what was explicitly taught. Knowledge: meeting the learning goals and expectations. Foundational knowledge: simpler procedures, isolated details, vocabulary. Limited knowledge: know very little details but working toward a higher level. Understand how our view of the solar system has changed over time and how discoveries made have led to our changing our view of the solar system. Learn planetary characteristics such as number of moons, size, composition, type of atmosphere, gravity, temperature and surface features. Understand the movement of planetary bodies. Understand which planetary characteristics are more important than others when it relates to our understanding of other worlds. Understand how proximity to the sun influences planets. Understand the methods and tools scientists use to learn about other planets and moons in our solar system. Understand the conditions needed for a habitable world and determine if there are habitable worlds in our solar system or outside the solar system. Understand how we look for and study solar systems other than our own.
This is a “light curve.” How are the planet’s size and orbital period shown in the light curve? TIME BRIGHTNESS The depth of the “dip” provides information on the size of the planet. The deeper the “dip,” the larger the planet. For a planet the diameter of Jupiter, the dip is between 1-2% of the starlight. For a planet the size of Earth, the dip is around 0.01%. The time between “dips” is the time between transits. The time between “dips” is the orbital period, or the “year” for the planet. An animation of a transit can be downloaded at: http://kepler.nasa.gov/multimedia/animations/ Select “Transit Graph” 2
Instructions: Choose a light curve. Chart 1: Record the planet name. Determine period of the planet (time between transits) using the online calculator, determine orbital distance. you need to go from hours or days to years for the graph to work Chart 2: Record the planet name. Determine light brightness drop % Calculate the square root of the light brightness drop % Multiply by 10 (T2)1/3

There are 11.2 Earth radii in 1 Jupiter radii So Divide your Earth Radii by 11.2
Due tomorrow at midnight (the same time as your current event!) Everyone must complete the table for all planets and then glue them into your science journal Then answer the 5 questions on canvas and attach a picture of your completed charts Don’t worry about answering the questions on the paper, they are the same as the ones online
