The document discusses web resources that can be used for accessing information and providing reference services. It begins by explaining how web-based resources allow for more up-to-date and accessible information compared to traditional reference services. However, using the web effectively requires addressing technical issues and maintaining intellectual control over vast amounts of information from various sources online. The document then provides examples of different types of science education websites that can serve as resources, including sites focused on the scientific process, field research journals, evolution, simulations, earth science data, and videos. It concludes by noting that web-based learning allows students to progress at their own pace compared to traditional classroom settings.
