Safety in the Science Classroom (Elementary) Presentation by Canton City Schools Science Curriculum 2006
Safety in the Science Classroom • Eye and Personal Protection • Fire and Heat • Handling Chemicals • Safety with Plants • Safety with Animals • Disposing and Clean-Up • Emergency Procedures
Eye and Personal Protection • Wear safety goggles when working with • Chemicals • Flying objects • Fire/flame/hot objects and liquids • Cutting glass • Gases under pressure
Eye and Personal Protection continued • Wear a lab apron and protective gloves when working with – Animals and plants – Chemicals • Learn about the eyewash and safety shower
Eyewash and Safety Shower EYEWASH SAFETY SHOWER
Safety Goggles, Lab Apron and Protective Gloves SAFETY GOGGLES LAB APRON PROTECTIVE GLOVES
Fire and Heat • Wear safety goggles • Tie back long hair and secure loose clothing • Do not heat FLAMMABLE liquids • Use a heat source in a safe area • Only the teacher uses the matches • Hot plates do not look hot and be aware of the electrical cord attached to the hot plate
Fire and Heat continued • Be careful of candle drippings- they can burn • Learn about the fire extinguisher and fire blanket • Only use glassware made for heating • Heated glassware does not look hot • Report broken glass to the teacher
Fire Extinguishers
The Science of Fires need three things to start and to continue to burn: • Fuel • Oxygen • Heat These three items are part of the fire triangle. Removing or disrupting one of the points will prevent the fire from starting or will extinguish the fire. Oxygen Fire Triangle Fuel Heat
Fire Blanket
Precautions BUNSEN BURNER HEATING TEST TUBES CANDLE HOT PLATE
Precautions HOT GLASS DOES NOT LOOK HOT REPORT BROKEN GLASS TO THE TEACHER
Handling Chemicals • Be careful when using instruments or equipment that contain chemicals in them - like thermometers and batteries • Never place chemicals in or near your mouth, eyes or nose • Smell solutions by waving your hand over the container • Never mix or use chemicals that are not part of the procedures in an experiment
