Science Safety Considerations

It is important that students always think about safety when conducting science investigations. This slide may be used to review safety with students prior to beginning. 

  • Always follow your district’s school 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 (e.g., safety goggles) is available.
  • Continually monitor the area where the investigation is being conducted.

Safety note: Caution students to be careful when handling food coloring as it can stain hands, clothes, work surfaces and equipment.
