Safety Considerations

It is important that students always think about safety when conducting a science investigation, and this slide may be used to review safety with your class before starting the activity. Also, keep the following points in mind.

  • Always follow your district and school safety guidelines.
  • Have a clear understanding of the investigation in advance (practice any investigation with which you are not familiar).
  • Make sure appropriate safety equipment, such as safety goggles, is available. 
  • Continually monitor the area where the investigation is being conducted.
  • Glass slides should be discarded in separate containers designed for glass and sharps disposal.

CAUTION

  • Iodine is toxic if ingested. Certain people are allergic to iodine. 
  • Iodine will stain the skin, but will gradually wash off. Iodine will permanently stain clothing and some table surfaces.
  • Be sure to read the information on the Materials Safety Data Sheet (MSDS), which should be available in the classroom during the activity. Materials Safety Data Sheets generally are provided by the supply company. Information also is readily available via the Internet.
