My Juniors and Seniors have chosen to take chemistry at the International Baccalaureate level. The selection means they have selected academic challenge over academic safety and more hours of work rather than less. They really love to get A's, but they are willing to risk a B or even a C to have the opportunity to learn chemistry at more advanced levels. They have also selected laboratory work after school. This maximizes both their lab practical time and their time learning the material they apply to their laboratory practical work.
The Sophomores are a very diverse group of academically gifted students who are still developing their love of learning.
They are enthusiastic about completing labs and seeing demonstrations of chemical phenomena. They are also a little anxious about possible accidents and risk of injury.
In the Chemistry laboratory we use many liters of diluted hydrochloric acid and sodium hydroxide solutions. We intersperse here and there with copper (II) sulfate solution, potassium thiocyanate, various nitrates, potassium permanganate, concentrated sulfuric acid, alcohols, and a few liquid hydrocarbons.
When the students' hands are protected from these chemicals, they are not only safer, they are more confident to work with them.
It is very helpful when the gloves fit as the student is able to maintain dexterity. Imagine a student working with a dropper bottle of concentrated sulfuric acid in a procedure to measure the concentration of dissolved oxygen in a sample of lake water. With a fitted glove, the student can manipulate small glassware easily and complete the transfer confidently.
