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.
Halite is a term for rock salt or sodium chloride. Halite is a simple ionic compound that precipitates out of a water solution so it is a chemical rock. The other rocks are made of more complex structures. Chemical sedimentary rock forms when mineral constituents in solution become supersaturated and inorganically precipitate.
