To the left, and at the bottom, is a list of all of the experiments in this series. Find the title of the experiment or activity and select it. On that page will be a series of pictures, videos, and/or documents that will allow you to "perform" the experiment. By perform, I mean you will be able to observe all of the necessary components of the experiment, including reactions and measurements. In most cases, you can pick up the lab worksheet in class. In some cases, the lab worksheet will be in a document form at the bottom of the web page.
