Group Work Defined
Working in small groups to solve problems is a great way to learn science. Here are a few documents to give group work some shape and definition so that it can be a
self-regulating learning tool:

Lab: Geiger Counter
Lab: The Geiger Counter
(Carried out as a demonstration in class).
Lab: Hard Water
an investigative style lab in which you must create your own procedure.
Group Activity: Atomic Structure II
Now we move on to cover the electron structure of atoms.
Homework: Atomic Structre II
more work with atoms, electrons and ionic charges
Lab: Intro to the Bunsen Burner
Activity: Chemical Formulas and Compounds
we will learn about bonding and ionic compounds
Here is the first
assignment that goes with this group activity.
Here is the second
assignment that goes with this group activity.
Here is an assignment
which uses an online applet to help you learn how to build ionic compounds from their ions. This is homework if not completed in class.
Lab: Solubility of Ionic Solutes

Important note regarding printing
Before printing turn off the optional header and footer information. Also, make the left margin 0.75 in
(1.9 cm) and the other margins 0.5 in (1.3 cm) so that the page breaks I built into
the pages work as intended.
Some of the
files are PDFs and you need the Acrobat Reader available from
Adobe. Some files are also MS Word 97 or RTF documents,
which just about anyone should be able to view. If you have trouble, try going
