The Van de Graaff (VDG) generator is ubiquitous in the physics laboratory, but the high-voltage discharges that emanate from it can cause user discomfort or damage to nearby electronics during experimentation. In this work, an augmented reality (AR) tool is developed to help students conduct the experiment safely. More specifically, it allows them…

Describes the construction and application of a device small enough to be worn on a worker's clothing that can monitor exposure to mercury. (MLH)

Analyzes the dangers of lasers in a classroom situation to formulate safety standards which are contrasted with federal regulations. Suggests that every laser user should check with the safety precautions to reduce the probability of producing a burn per student contact to extremely low levels. (CC)

Discusses the possible dangers of the educational radioactive sources used in a college physics laboratory. The discussion is intended to increase the awareness of teachers and students. (HM)

Experimental data, Federal and State regulations, and user data are presented to assess the safety factors of low-power lasers. General safety precautions, basic laser theory, the place of the laser in the classroom, and some introductory exercises are also presented. (Author/TS)

Describes safety hazards encountered when placing squash balls into liquid nitrogen. Suggests using racquet balls, balloons, or economical Ping-Pong balls. (MVL)

Using hypothetical lawsuits as examples, the more common rules of law which define the acceptable conduct of a physics teacher in the classroom, laboratory, and general school area are examined. (BT)
