electricity and magnetism

< < Lecture 27 Lecture 29 > > Practice Activities (Once I have some practice activities or HP5 stuff, it will go here.) Resources (Will post some when I have some) Video Transcript (Will post when I have a script.)

< < Lecture 26 Lecture 28 > > Resources Color wheel – Learn about color theory and what colors look good together and why. PhET Color Vision Simulation See how combinations of varying intensities of red light, green light, and blue light combine to make any color.

< < Lecture 24 Lecture 26 > > PhET Faraday’s Law Simulation Faraday’s law explains the relationship between coil size, number of windings, rate of change of the magnetic field, and the induced voltage. See how bright you can get the lightbulb to light up by changing different parameters.

< < Lecture 23 Lecture 25 > > Resources Magnetic Storm – This PBS video is all about the Earth’s magnetic field. Did you know the Earth’s magnetic field protects us from solar radiation, and that it has changed in direction and magnitude throughout the planet’s history? Ancient trees show Read more…

< < Lecture 22 Lecture 24 > > Resources Resistor color codes graphic (PNG) – Learn how to decode the color codes on a 4-band resistor using this chart. Voltage, current, resistance, and Ohm’s law – This tutorial page from SparkFun contains a lot of information about Ohm’s law and Read more…

< < Lecture 21 Lecture 23 > > PhET Balloons and Static Electricity Simulation Rub a balloon on a sweater, then stick it on a wall and see how induction in insulators (also known as polarization) works. PhET Coulomb’s Law Simulation Modify the value of two charges and their distance Read more…
