Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...

Test six various reagents for their ability to conduct electricity. Cooperating chemists research whether each is ionic or covalent and discover the relationship between bonding and conductivity. This laboratory exercise would be an...

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...
