Chemical and Physical Changes

Though it states that it is a worksheet, this technically is a set of directions for a series of six activities exploring physical and chemical changes. Chemistry or introductory physical science aces examine carbon dioxide production of yeast, burning of sugar, heat produced when water is added to calcium chloride, and more. Each mini procedure asks participants what happened. They could record observations in a science journal leaving these handouts for reuse.

What I like about this website are the numerous worksheets that are available. So far I have not come across any difficulties when working with this site.
