Chemical Activities Involving Reversible Thermochromic Pigments

The color of a thermochromic system depends on its temperature. The colors of leuco dye-based systems can also be influenced by adding acids or bases to the thermochromic reactions. These can be used to create colorful demonstrations of acid-base chemistry. Thermochromism found in color changing cups can also be used to visualize heat flow, and therefore thermodynamic principles, associated with stretching and contracting elastomers.

Keeping Simulations Simple with Javalab

Javalab is a resource for free simulations to support student understanding of chemistry concepts. These web based simulations can be used across different platforms and are simple in their use by students. The open ended aspect of the simulations allow for teachers to be creative in how they are used in class.
