                      What is going on this
                      picture?

                      What are some
                      things you know are
                      unsafe to do during
                      lab?


                      What are some
                      things you feel
                      might be unsafe to
                      do during lab?
      Playing Safety Symbol Bingo
• In the following slides, you will see a safety symbol that is
  represents an element of laboratory safety.
• Guess the symbol as a class and then record the picture on
  your bingo sheet.
   • Place a bean or item provided to you.
     Please do NOT mark on the bingo sheets!
   • You only really need to know what the symbol means, the rest is
     common sense. (You can download all these slides from my
     webpage if you want to know all the information later.)
   • If You have Bingo, please wait until the end and we’ll check it.
   • We’ll keep going until we go through all 10 lab safety symbols.

• Afterwards, we’ll recap by examining photographs and
  determining what laboratory safety rules are being broken!
• Get ready and good luck!

Safety Goggles
       • Used for Eye protection.
       • The most common used
         safety item in the biology

                     Reflect:

                     As a class, let’s review some
                     of the safety violations that
                     we can see.

                     What were some things you
                     saw at the beginning?

                     What are some things you
                     see now after learning about
                     lab safety?


                     Any Questions about
                     Lab Safety and
                     Safety Procedures?
            Now let’s play a Game…
• In efforts to get to know another and make good
  observations/inferences, I’m going to give your lab bench a
  phrase.
• The first person reads the phrase I wrote and draws a
  picture of how they would communicate it to the next
  person.
   – They fold down the phrase and pass it down.
• The next person looks at the picture and writes a
  description of what is happening.
   – They fold down the picture and pass it down.
• Continue in this pattern until you reach the end of the row.
   – We’ll share our results! And NO PEEKING!
