Each Biology InterActivity presents a single concept or process that is best understood in an interactive, multimedia format. The simulations enable students to visualize processes that occur on a micro scale or to understand interactions on a macro scale.

	For some topics, the InterActivities present abstract concepts that students cannot visualize or cause-and-effect relationships that cannot be demonstrated using traditional classroom methods. For these concepts, our virtual labs represent the only practical means of instruction.
	Our InterActivities also complement the teaching of concepts for which hands-on labs offer an incomplete explanation. Many biology concepts or processes are not amenable to hands-on learning or are recognized as difficult to teach. Our virtual labs address these needs.

Our biology materials map to the National Science Education Standards as set by the National Research Council.

The heart of each biology topic is the interactive BioScope. Tailored to the needs of each topic, it lets students view processes and manipulate their components, alter variables to see their roles in processes, or alter reality to discover cause-and-effect relationships. Step-by-step instructions for using the BioScope are included in the Lab Manual. Supplemental materials include background information, data tables, graph templates, and a glossary.
