Science Safety Considerations

Students always must think about safety when conducting science investigations. This slide may be used to review safety with your class prior to beginning the activity. 

Safety first!

  • Always school district and school science laboratory safety guidelines. 
  • Have a clear understanding of the investigation in advance. 
  • Practice any investigation with which you are not familiar before conducting it with the class. 
  • Make sure appropriate safety equipment, such as safety goggles, is available. 
  • Continually monitor the area where the investigation is being conducted.

Safety Notes

  1. Do not let students test saliva, tears or any other body fluids.

  2. Do not let students open the petri dishes once they have been closed.

  3. Refer to the lesson PDF for proper disposal of materials.
