I enjoy the challenge of answering any type of question, but please don't post homework questions just "blank"; include something to show you've had a go :-)
I'm a lecturer in chemistry and chemical education in York, UK, and I also act as a Hazchem adviser to the Fire Service, providing chemical safety information to first responders. My professional role also includes providing emergency poisons advice to UK medical practitioners.
Journal of Chemical Education TES Plus independent book publications.
BSc Chemistry (University of York 2005) PhD Chemistry (NYU) PGCE Teaching Certification
I have previously volunteered in this category, but owing to an email problem, I am re-regestering. I have taught for both Nottinghamshire and Yorkshire education authorities and for several independent youth organisations. I provide continuing support for North Yorkshire Fire and Rescue Service and the UK Poisons Information Service (London-Based).
I love the deep, underlying chaos and lack of order facing us as we explore the world of atoms and molecules.....that, and illicit sniffing of the ether in the lab :-) I have always found science fascinaing, and to me the tactile nature of a lot of chemistry makes it even more amazing.
To go on learning forever; I love teaching because you learn so much!

Hi, and thanks for the follow-up Err as in "commit an error"; http://www.merriam-webster.com/dictionary/err I just meant it's better to make the jelly too thick rather than too thin, so if in
Salt-based flour dough should work ok as a modelling agent provided it's not in contact with liquids. And we usually just make the jello using the amount recommended by the manufacturer on the packet;
Hi, thanks for the question. The reason that you probably shouldn't go with the "liquidy" jello is primarily that you're relying on the integrity of the set jello to prevent mixing; jello that's liquid
