Day 145: How Does the Sun Rotate?
College-Prep Physics: Today we used the data from our sunspot log to determine how fast the sun rotates. Do the sunspots speed up, slow down, or move at constant speed? Do all places on the sun rotate at the same rate or does it depend on latitude? The lab handout is here: LAB Solar Rotation 2013
Conceptual Physics: Students used the PhET circuit simulation to explore how current and voltage behave differently in series and parallel circuits.
