2. Safety First • Science is a hands-on laboratory class. • You will be doing many laboratory activities, which require the use of potentially dangerous materials and expensive lab equipment. • Safety in the science classroom is the #1 priority. • To ensure a safe science classroom, certain guidelines must be followed at all times.

3. General Safety Guidelines • Be Responsible at all times. No horseplay, practical jokes, pranks, etc. • Follow all instructions carefully. • Always get permission to do an investigation. • Always use science equipment the way you are supposed to. Handle the equipment with care; they are tools, not toys. • Keep your work area neat and clean. • Never taste anything unless you are instructed to do so. Lab Safety: Everyone Is Responsible!

4. General Safety Guidelines • Dress appropriately. Roll up long sleeves. Long hair should be secured to the back of your head so it does not get in the way. • Always wear the correct safety equipment. • Notify the teacher immediately of any accidents or unsafe conditions in the science classroom! • Know what to do in case of an emergency. • Always wash your hands with soap and water after experiments.
