These 106 in-depth tutorials are designed to illustrate and explain some of the many complex topics in biology. Each tutorial has four elements: an introduction that describes the topic to be illustrated and puts it into a broader context, a detailed animation that clearly illustrates the topic (there are a few tutorials that include simulations or other types of content, rather than animations), a conclusion that summarizes what you should have learned from the animation, and a quiz on the topic covered.

Embryo Images Normal and Abnormal Mammalian Development is a tutorial that uses scanning electron micrographs (SEMs) as the primary resource to teach mammalian embryology. The 3-D like quality of the micrographs coupled with selected line drawings and minimal text allow relatively easy understanding of the complex morphological changes that occur in utero. Because early human embryos are not readily available and because embryogenesis is very similar across mammalian species, the majority of micrographs that are utilized in this tutorial are of mouse embryos. The remainder are human.

With support from the National Science Foundation, we assisted in developing bioinformatics curriculum for high schools and popular bioinformatics tutorials that are used in both college and high school classes. We have shared these materials at several Bio-Link workshops, and at workshops sponsored by CCURI, Tulsa Community College (SEEDBed award), and DelMar College.  Digital World Biology is also partnering with the Amgen Biotech Experience at Shoreline Community College to assist in providing professional development opportunities for high school teachers.

Many factors are known to be important in disease causation and these can include an individual's age, gender, genetic make-up and environmental factors that they have been exposed to, such as infectious agents or chemicals.

2 min video A quick tutorial, showing how we use restriction enzymes to cut out a desired gene from one organism, and insert it into the plasmid of a bacterium. This allows massive production of the desired protein (in this case the hormone: insulin) in a relatively short amount of time.

In this tutorial you will be learning about the Linnaean system of classification used in the biological sciences to describe and categorize all living things.  The focus is on finding out how humans fit within this system.  In addition, you will discover part of the great diversity of life forms and come to understand why some animals are considered to be close to us in their evolutionary history.

Life sciences focus on all things living, exploring the patterns, processes and relationships of organisms. The goal of life sciences is to demonstrate how unifying principles can help us to make sense of the natural world and solve problems in the world we live in. High school life sciences extend student knowledge of topics such as organisms, ecosystems, heredity and evolution, integrating a long history of scientific research from multiple fields. In high school, students will build on their conceptual understanding of life sciences by investigating and witnessing the relationships among structure and function, matter and energy, ecosystems and natural selection. Students should be able to effectively communicate facts and findings, as supported in the science literacy skills covered in the Common Core State Standards.
