Product Description

Do you need a break from quantitative data and numbers in your chemistry lab? Sometimes I sure do (and so do my students!) In this lab, students go back to fundamentals...making good data tables, recording detailed observations and using their findings to categorize a large sample of elements and mixtures as either metal, non-metal or metalloid.

The lab includes the entire student packet - with background, pre-lab, procedures, opportunity for to create their own methods, lab safety, clean up and analysis. It also includes a sheet of teacher notes and the answer sheet.

This lab takes my Grade 10 College Prep chemistry students about 3 hours to my school with 55 minute classes, we need 3 days. This is not a "quickie lab." I use it as a break typically right after a test. It fits anywhere in the Chemistry curriculum but my suggestion would be either early in the school year or right after you teach the atom, elements and properties. It is a great intro to periodicity (this is where I use it).

The only technology you'll need is conductivity testers. The samples are listed for you on the teacher's notes page and there isn't anything that is obscure - every high school chem lab should have these readily stocked. The lab is completely modifiable for you to make changes as can even swap out samples to better suit what you have on hand.

This is a great lab for your students to "get away from all the numbers" for a bit and return to other skills - like writing clear methods, recording good data and making careful observations and analysis.

Have fun!
