Lab Safety

Exploring, inventing, and investigating are all essential to the study of science. However, these activities can also be dangerous. To make sure that your experiments and explorations are safe, you must be aware of a variety of safety guidelines. You have probably heard the saying, “It is better safe than sorry.” This is particularly true in a science classroom where experiments and explorations are being performed.

Stop!

Reflect on page L of your IAN why you think it could be important to learn about lab safety rules. Reflection can be in the form of a drawing of what could go wrong, or in a poem. Be creative, colorful, and have fun!

Being uninformed and careless can result in serious injuries. Don’t take chances with your own safety or with any else’s.Always get your teachers permission before attempting any laboratory exploration. Read the procedures carefully, and pay particular attention to safety information and caution statements. If you are unsure about what a symbol means, look it up or ask. If accidents occur, inform your teacher immediately regardless of how minor you think it may be.

Please leave all backpacks in the science room when working in the science lab. There is never any food or drinks allowed in the science lab. During warmer weather, water bottles can be left on the main table as you enter the lab. Clean up your table when you are done, and put back any materials you used where you found them.
