Using Water Chemistry as an Indicator of Stream Health
Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

Chemical Kinetics
Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...
