The ACS Committee on Chemical Safety has released the 8th edition of "Safety in Academic Chemistry Laboratories". The publication provides advice for first- and second-year university students.
Students can build their own Hoffman apparatus. An animation of the electrolysis on a particulate level is available to show students before, during or after students perform the electrolysis.

Students will be engaged in this activity that will help them make the connection between food and chemistry. Acid, bases and pH are addressed.
This blog post may be a bit non-traditional, but in this submission I recall a memory from early in my teaching career when my dad (who was an environmental chemist) visited my classroom. The day remains embedded in my memory bank, and had a profound impact on how I view labs - as an opportunity to extend the learning.
I tend to enjoy acid base titrations for several reasons. First, students get to work with burettes, acids, bases and they see a nice "color change" when they reach an endpoint. Many times, students who tend to struggle with pen and paper testing excel at the "hands-on" approach. Titrations also dovetail well with stoichiometry which provides a nice review of information closer to the end of the year.
I think this experiment provides a fantastic vehicle to involve students of all ages in small, hands-on and exploratory research projects. Like many others, my students and I have investigated various aspects of this interesting fountain.
