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.
Secondary links. Bentonites. Definition: Bentonite is defined as a naturally occurring material that is composed predominantly of the clay mineral smectite. Most bentonites are formed by the alteration of volcanic ash in marine environments and occur as layers sandwiched between other types of rocks. The smectite in most bentonites is the mineral montmorillonite, which is a dioctahedral smectite but occasionally other types of smectite may be present.
