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!

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!
