I made ScienceFix.com to share my favorite demos that I do in my middle school science classes.

Video Demo: Water Electrolysis

I recently presented at the CSTA Conference and I was able to pick up a few new demonstrations.  In the past it was really difficult to demonstrate or do a lab activity that involved the electrolysis of water.  Luckily I sat in on Tara Krisch's (Orange Grove Middle School) presentation on compounds.  She shared a simple way for students to do water electrolysis.  The second demo also shows electrolysis, but in a slightly more colorful way.

I highlighted your post in my Daily Digest of Education related blogs today as I thought other teachers would find it of interest. You can see it here: http://bit.ly/gPGftV

Very nice video of the demonstration. I'm doing the same thing on my site with some labs and demos.

I give tuition and very often i am challenged to make the lessons as simple as possible ensuring that the students clearly understand what is being taught to them. I am glad indeed to come across your very simple yet innovative site. Thanks much :)
