My physics students have a misconception of what heat and temperature are. Technically cold doesn't even exist! The molecules are just moving slower. How do your students do in the classroom with this topic?

David posted what he thought Matter was and how it is effected. What caught my attention the most is how I thought there were only physical states of matter, but there is so much more. I had not idea that an electrical charge was a property of matter. How cool! Different types of light can affect how something looks. Different energies of light can alter how matter is seen. I will remember this when looking at something to determine or describe its color because there are so many facors.

Here is the tutorial on Alternating Current.It covers concepts like what is Alternating current?,Generation of AC,advantages and disadvantages

I think this is the best photo of the Ohm,s Law becouse it explains you how to calculate resistance, current and voltage. Ohm's Law is the mathematical relationship among electric current, resistance, and voltage. The principle is named after the German scientist Georg Simon Ohm.
