About Science Prof Online PowerPoint Resources

Science Prof Online (SPO) is a free science education website that provides fully-developed Virtual Science Classrooms,science-related PowerPoints, articles and images. The site is designed to be a helpful resource for students, educators, andanyone interested in learning about science.

The SPO Virtual Classrooms offer many educational resources, including practice test questions, review questions, lecturePowerPoints, video tutorials, sample assignments and course syllabi. New materials are continually being developed, so checkback frequently, or follow us on Facebook (Science Prof Online) or Twitter (ScienceProfSPO) for updates.

Many SPO PowerPoints are available in a variety of formats, such as fully editable PowerPoint files, as well as uneditableversions in smaller file sizes, such as PowerPoint Shows and Portable Document Format (.pdf), for ease of printing.

Images used on this resource, and on the SPO website are, wherever possible, credited and linked to their source. Anywords underlined and appearing in blue are links that can be clicked on for more information. PowerPoints must be viewed inslide show mode to use the hyperlinks directly.

Several helpful links to fun and interactive learning tools are included throughout the PPT and on the Smart Links slide,near the end of each presentation. You must be in slide show mode to utilize hyperlinks and animations.
