Wherever there's an item of value, from artwork to currency to GucciTM bags, there are counterfeits. But now science has offered a new and perhaps foolproof method of tagging genuine items: DNA sequences. As this USA Today article reports, DNA sequences from Olympic athletes were used in the ink on Sydney 2000 Olympic souvenirs. The only remaining question is, Will the DNA hold up in the wash?
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
