By the end of this section, you will be able to:Define matter and elementsDescribe the interrelationship between protons, neutrons, and electronsCompare the ways in which electrons can be donated or shared between atomsExplain the ways in which naturally occurring elements combine to create molecules, cells, tissues, organ systems, and organisms

Material Type: Module


(View Complete Item Description)

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Virtual Cell Animation Collection

(View Complete Item Description)

The Virtual Cell Animation Collection currently contains 24 animations in 3D and with motion, which cover many molecular and cellular biology (MCB) topics. The Animation Collection is available on a website (, a YouTube channel (, and as an Apple iOS app. Biology education research indicates that 1) multiple viewing of animations increase learning gains beyond a single viewing either before a lecture, as in a “flipped” classroom, or during a lecture, 2) increased learning gains result from engagement with animations over engagement with static graphics, and 3) students perceive that engagement with animations greatly facilitates their understanding of MCB processes.

Activities for engaging students in Biology using animations

(View Complete Item Description)

This resource includes three classroom-tested activities that were created using the ideas outlined in the article “Getting more out of animations” by Pruneski and Donovan (in press). The driving idea is that animations can be a powerful tool for learning complex biological processes, but when students are passive viewers, it limits their usefulness and may become simply another source of content to be memorized. Engaging students with animations can greatly increase the amount of information that can be extracted and can help students develop important learning skills that can be useful in the future. These sample assignments help make the use of animations more effective and active by structuring student viewing using guiding questions. These questions focus on particular objects, features, or steps of the process to help students accomplish specific learning objectives for that topic. The assignments also help students think about animations as media objects that are created by scientists and animators using specific tools and conventions that affect how the process is depicted and the ways in which it should be viewed. Lastly, by comparing and contrasting multiple animations of the same process, students can extract more information, overcome the limitations of each individual animations, and generate a more complete view of the process.

Logic Puzzle

(View Complete Item Description)

This activity is intended as an exercise in deductive logic. The students perform a series of "experiments" in which they try to identify which predators eat which specific prey (Each predator eats one and only one prey). The instructions are on the site. students may also click on the blue square to make the game full screen. A worksheet is added for students to record their results. This also is an exercise in articulating the logic used in the study. (Most students have no trouble figuring out the relationships). Writing down their results and conclusions is a bit trickier. ) This has been used for community college classes. It can be used at lower levels such as high school or even middle school without the worksheet.
