Experiment Central Parent's and Teacher's Guide

The experiments and projects in Experiment Central have been carefully constructed with issues of safety in mind, but your guidance and supervision are still required. Following the safety guidelines that accompany each experiment and project (found in the "How to Experiment Safely" sidebar box), as well as putting to work the safe practices listed below, will help your child or student avoid accidents. Oversee your child or student during experiments, and make sure he or she follows these safety guidelines:

• Always wear safety goggles if there is any possibility of sharp objects, small particles, splashes of liquid, or gas fumes getting in someone's eyes.
• Always wear protective gloves when handling materials that could irritate the skin.
• Never leave an open flame, such as a lit candle, unattended. Never wear loose clothing around an open flame.
• Follow instructions carefully when using electrical equipment, including batteries, to avoid getting shocked.
• Be cautious when handling sharp objects or glass equipment that might break. Point scissors away from you and use them carefully.
• Always ask for help in cleaning up spills, broken glass, or other hazardous materials.
• Always use protective gloves when handling hot objects. Set them down only on a protected surface that will not be damaged by heat.
• Always wash your hands thoroughly after handling material that might contain harmful microorganisms, such as soil and pond water.
• Do not substitute materials in an experiment without asking a knowledgeable adult about possible reactions.
• Do not use or mix unidentified liquids or powders. The result might be an explosion or poisonous fumes.
• Never taste or eat any substances being used in an experiment.
• Always wear old clothing or a protective apron to avoid staining your clothes.
