What is thermal conductivity? The ability of a material to transfer heat energy via conduction.

While this is only the first trial, my task was to show that there is a significant drop in thermal conductivity of a material as it shifts from one phase to another. In this case, the sample shifts from a solid to a liquid around 18 oC. As you can see, the thermal conductivity is lower for temperatures higher than 18 oC. Cool huh?

When I am done, I will commit an entire page to show everything from beginning to end. Really I just want post the graph on twitter, but I know people will ask questions so….

Technology in the Classroom

Powerful, flexible graphing calculator . . . and it’s free!

Does far more than most of the paid calculators out there . . . let alone the free ones.

This is how my students graph linear equations in standard form ( Ax + By = C):

**Description:** In this activity students explore the characteristics of various function families by comparing the patterns in six different tables of values and identify which type of relationship is shown in each one.
