This is a 160-gram tub of diatomaceous earth sold as a classroom science material by Delta Education, a school-supply brand. It is a fine, powdery mineral used in lessons on fossils, filtration and absorbency. The package is small, so it suits a single demonstration or a few lab groups rather than repeated classroom use. It is a straightforward consumable with no scoop included, so plan on your own measuring tools.
