The info that I gain from these assessments is so important to me. It gives me a starting point for my instruction. It also gives me data that I can share with parents as we progress through the year. Like many of you, all this info goes into a giant binder. This binder has a tab for each student and most of the materials (such as extra recording sheets and various flash cards) I need to complete assessments.
Lewisite is primarily a vesicant (causing blisters). It secondarily irritates the lungs and is a systemic poison. Upon contact with the skin, it causes large, painful, fluid-filled blisters, especially on the extremities, back, and scrotum.
Magnetite is a mineral, one of the three common naturally occurring iron oxides (chemical formula Fe3O4) and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth.Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism.mall grains of magnetite occur in almost all igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5â6 and a black streak. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide.
