Please note that we neglected to schedule all of the book Weather in the Science K Biology, Botany, and Physics Instructor's Guide. Please complete the book in Week 3. We apologize for this error and the confusion it has caused. (10/2009)

Please note that there is an error on the footer of the Biology, Taxonomy, and Human Anatomy Cut-Out Sheets in Science 3. Although the erroneous footer indicates that these Cut-Out Sheets belong in Science K, please be assured that this is not the case. These Cut-Out Sheets do, in fact, belong with the Science 3 Instructor's Guide. We apologize for any confusion this error may have caused. It has been corrected for future printings of this guide.

In the Introduction to some of our new 2009 Science Instructor's Guides, there may be instructions regarding how to use moveable tabs provided with the Answer Keys. Please note that, because of the new format of the 2009 Science Instructor's Guides, the moveable tabs are no longer necessary and are thus no longer included with the Answer Keys. Each week's Answer Keys are now located within each particular week, along with the corresponding Activity Sheets. Since there is no need to flip back and forth between Activity Sheets and Answer Keys, the moveable tabs are no longer included in your Instructor's Guide. We apologize for any confusion this may have caused.

Please note that the supplies listed for the experiment in Week 3 of Electricity, Magnetism, and Astronomy are incorrect. We apologize for any confusion this error may have caused. (8/2009)
