Provide enough wait-time for students to reflect when responding to inquiries. Provide emotionally supportive environments in the classroom encouraging reevaluation of conclusions. Prompt reviews of the learning situation, what is known, what is not yet known, and what has been learned.
Polyurethane is a fully reacted polymer in which every molecule bonds with another so it is chemically inert, which keeps it from oxidizing or leaching chemicals, theoretically extending tire life. Tires of the future?
Water-based, oil-modified polyurethane is a hybrid mix of oil- and water-based polyurethane. It is more durable than regular water-based polyurethane. This type of polyurethane comes in a brush-on and a wipe-on form. Apply three coats of the brush-on form using a synthetic filament brush or spray. Each coat takes two hours to dry.
