Lab protocol

• First and last name on your lab sheet NOW!• Goggles at certain stations – you MUST wear them or you

will sit out the remainder of the lab day. Safety comes first!

• Complete your lab sheet to the best of your ability. Be specific and thorough in your answers.

• Listen for my signal to switch stations in numerical order• Review each station for tips and safety guidelines.• Make sure to circle P or C for each one!– When everyone is done, we’ll share our conclusions!

Foldable directions…

• Which tab should this be written on…–One or more substances are changed into a new

substance that has new and different properties.–Describes matter based on its ability to change

into new matter with different properties. These properties can only be observed during a chemical reaction.– This change does not form a new substance.– These properties can be observed without

changing the identity of a substance.
