Activiy shows need for replication
I found that in one class, nobody got a clean 2:1 ratio, but all had more hydrogen. In other classes, got some 2:1 gas ratios, and really drove home the point of replication. I think kids had some powerful A-HA! moments!

Good tip! I am planning to do this lesson sometime later this semester. I will definitely test it out beforehand to see how to optimize the setup for the device.
