Chapter Overview During this unit, students demonstrate safe practices, including the use of personal protective equipment, such as safety goggles. They also learn the locations and use of other types of safety equipment, such as fire blankets, eye wash fountains, safety showers, and fire extinguishers. Students are introduced to safety information contained in MSDS/SDS. Students also learn to conserve and dispose of materials appropriately. Finally, students develop their own science notebooks to collect, record, and analyze data and information.. Main Ideas Scientific investigations should be conducted in a safe, environmentally appropriate, and ethical manner. *What should be considered when appropriately conducting a scientific investigation and why? Scientific processes lead to valid conclusions. *Why is it important for a scientist to maintain thorough documentation of all work? Misconceptions ***Students may think all chemicals are hazardous. ***Students may have difficulty understanding that all matter is chemical. Students may have difficulty understanding that the amount of chemical exposure determines toxicity. Vocabulary Material Safety Data Sheets (MSDS) – MSDS are information
sheets provided for each chemical used or stored in the chemistry lab or
classroom. These are required to be made
available so that the hazard potential (such as flammability, corrosiveness, radioactivity)
can be assessed and proper safety and clean-up precautions taken. Flammability – the ability of a substance to burn or ignite,
causing fire or combustion Corrosiveness – the ability to cause damage to living tissue Radioactivity – the sending out of radiation Toxicity – the action of poison on living beings Personal Protective Equipment (PPE) – safety goggles,
aprons, gloves Eyewash Fountain – sink used to flush eyes with water when
irritants or chemicals enter the eye Fire Blanket – safety device designed to put out (smother)
fires Fire Extinguisher – device that discharges a jet of
substance to put out a fire Fume Hood – ventilated enclosure in a chemistry lab where
harmful chemicals can be used Safety Shower – shower to wash chemicals off a person after
a chemical spill Disposal – getting rid of something Notes        Other Valuable Resources |
