This is easily two lessons in one. There is one PPT that features information about how to effectively search the web, and it features another section describing different resources and which ones they should use. It discusses everything from search terms to atlases.
It also includes a worksheet for web-based research for students to use while viewing the PPT, and it includes a worksheet for the resource book section of the PPT. Both worksheets are available in this download as a .DOC and .PDF format.
There is even a quiz at the end of the PPT as a review over what types of resources are best to use in different scenarios.
