Students can do an experiment studying enzymes by placing a slice of pineapple on Jello. They can see, both in their own experience and in the photographs, that the enzymes in the pineapple change the protein in the Jello resulting in its change from solid to liquid. There are fifteen questions in the reader's poll, and after each question is answered, the up to the minute results are displayed. The students can then see how prevalent their opinions are. Students may access a bulletin board where they can post, read,or answer questions from others who have visited this site.
Teachers can find additional links in the interactive section.
Color drawings and photographs are found throughout. Link to download site available.
