LABORATORY SAFETY ESSENTIALS MULTIPLE DEMONSTRATION KIT

Product Details

The most important lesson for students to learn in science is also the first—safety first! Engage students’ interest in the essential rules of laboratory safety with this set of four persuasive demonstrations.
• Acid in the Eye—Put on your goggles! Adding strong acid to an egg white causes irreversible damage, just as it would to proteins in body tissue. Wearing proper laboratory protection is non-negotiable!
• Grease Fire—Never use water to extinguish a grease fire. Pouring water on melted candle wax causes a fireball to erupt and jaws to drop!
• Flaming Vapor Ramp—The hardest concepts to understand are those we cannot see! Reveal the invisible hazards of flammable gases by igniting hexane vapor poured down a metal track.
• SDS Challenge—Students identify a mystery chemical by applying the information found on the Safety Data Sheets. A great inquiry-based activity!

A great value—four safe ways to illustrate common laboratory safety hazards.
