Energy, Heat, and Temperature

It is all about the heat equation that you see above. For a fun way to learn the equation, go to this YouTube video created by a chemistry teacher and musician. It has a catchy, rap beat that will stick in your mind 'cause "It's monkey, funky cool".
Each lecture is about one part of the equation with a wrap up of how to use the entire equation at the end. Lecture 1 will focus on the q in the equation which is heat. That topic is the part that is in orange on the concept map. Lecture 2 will focus on the delta (triangle) T which is the change in temperature. The concept map shows that topic in blue. Lecture 3 will be on heat capacity which is the c in the equation and is purple on the concept map. The last lecture, lecture 4, pulls everything together and the students begin to work with the algebraic problem solving needed to be able to solve for any particular variable in the equation.
Labs in this module will explore calorimetry, heat conduction, and some of the questions posed in the concept map.

Heat Capacity
In the third lecture, will focus on what heat capacity is and how larger numbers indicate that a substance is harder to heat than another substance of lower heat capacity. We will also discuss how the heat capacity is a characteristic of a substance.
Edition 1 and edition 2 have two different types of charts for the heat capacity. Be sure that you use the chart provided in the course page so that your answers on the quiz will work out as a match to what the quiz is looking for.

The Full Equation: q = mcΔT
In the 4th lecture we will begin working wit the full equation. A fun way to remember the equation is to listen to a musical chemistry teacher named Mark Rosengarten in is rap rendition of the equation. Even if you are not a big fan of rap, this playful and memorable song will get that equation nailed right down in your memory. Click on the image to the left of HERE to go and listen.
Labs
Calorimetry Lab
Our primary lab focus will be on how to perform calorimetry. Using calorimetry, you can compute the heat capacity of an object. This information can be put to many uses including identifying what an unknown substance/object is.
We will also explore some ideas for additional labs and get challenged by an interesting question regarding what has more heat energy: a lit match or a 3 foot tall ice sculpture.
