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.
Re: Helenite..Don't Be Fooled! Helenite is glass in the same sense that natural obsidian is glass. Helenite is synthesized from ash from Mount Saint Helens. It is an absolutely beautiful material - especially the stones that are four carats or more. I own scores of different types of natural gems - including zultanite, color change garnet, apatite. I never - almost never - buy synthetic stones, but helenite is absolutely gorgeous. I have become a fan.
