1. Lab Safety Symbols

2. You see symbols all around you
You see symbols all around you. You knew the answers immediately what they meant. That’s because symbols convey (give) a lot of information in a split second.
Symbols are used in science labs, too. They are used to caution us against accidents and harm. These symbols need to be simple so that we can understand their meanings in a split second.

3. The following are safety symbols used in businesses around the world
The following are safety symbols used in businesses around the world. What are the cautions that they convey? (Just share your ideas aloud for 2 minutes only. Use the clock on your computer to time yourselves. These symbols will NOT be on your upcoming test; Ms. Tresten just wants you to see how easy it is to interpret good safety symbols.)

12. What does this symbol tell you?
We know if you drop something that is glass in class, the first thing you should do is tell the teacher. What should you do if you get your lab supplies and notice a beaker is chipped? If
Tell the teacher!
