I've been searching some of the sites given in our workbook and after the activities. As often happens, there are a few I couldn't find. I don't know if this is due to my own ineptitude (I'm not that great on the web) or because they closed down. The sig figs sites interested me because I was looking for a place my students could go to practice them. Some of my regents students still don't have the concepts down. Professor Logan's site off of angelfire.com looked promising, but after trying it, it seemed a little confusing. There were 2 others; one to practice computations with sig figs and one to tell the number of sig figs. Those were 2 of the ones I couldn't get to. Did anyone else have luck with them?
I love the nuts and bolts analogy of electrolytes. I use nuts, bolts and screws when we go over atoms, molecules, etc. and this is a great way to extend it.
I'm really enjoying these sessions, but I wish I was with a group rather than doing it by myself.
Have a great week.Talk to you soon.
