Performance Standard Level 2, Ages 8–10

Students examine laboratory and community safety procedures, identify how an individual affects the safety of the group, and practice safe behavior in the classroom and laboratory.

Sample Assessment Ideas

blue rule

Sample Assessment Ideas

  • Students review lab safety procedures; draw lab safety posters illustrating the procedures.

  • Students identify ten safety features in the community (guard on snow-machine clutch, kill-switch on outboard motor or snow-machine, railings on stairs, and so on).

Expanded Sample Assessment Idea

blue rule

Expanded Sample Assessment Idea

  • Students review lab safety procedures and model incorrect and correct approaches for the critique of their peers.

Procedure

Students will:

  1. Review lab safety procedures.

  2. Witness demonstrations of procedures by instructor.

  3. Practice proper procedures.

  4. Pantomime performing a task in the laboratory until stopped by the observation of their peers of a non-safe behavior.

  5. Pantomime the proper approach after it is described by peers.

Reflection and Revision

Develop a list of other areas of the school that can benefit from safety procedures.

Standards Cross-References
( Alaska Department of Education & Early Development Standards)

National Science Education Standards

The potential for accidents and the existence of hazards imposes the need for injury prevention. Safe living involves the development and use of safety precautions and the recognition of risk in personal decisions. Injury prevention has personal and social dimensions. (Page 168)

 

Benchmarks

One person’s exercise of freedom may conflict with the freedom of others. Rules can help to resolve conflicting freedoms. (Page 172)
