Science/Strand IV/Content Standard 1/Elementary
Benchmark 5
Describe possible electrical hazards to be avoided at home and at school. (K-2)

Benchmark Clarification

Electricity is dangerous and household accidents with electrical outlets and appliances may cause personal injuries and fires. See Electrical energy, (SCI.IV.1.E.3).

Students will:

  • Identify possible electrical shock hazards such as wall outlets (sockets), frayed wiring, and downed electrical lines
  • Describe how to avoid possible electrical shock hazards
  • Explain why objects or body parts should never be inserted into outlets or electrical appliances

Instructional Example

Benchmark Question: What are electrical hazards?

Focus Question: What are electrical hazards at home and school?

Through illustrations, students will teach their classmates about common electrical hazards. Students may dramatize safety rules for encounters with electrical hazards from wall sockets, appliances, downed electrical power lines, or frayed wiring. Students will investigate and report electrical hazards in the classroom/school.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.5), (SCI.I.1.E.6).

Reflecting: (SCI.II.1.E.1), (SCI.II.1.E.2), (SCI.II.1.E.3).

Assessment Example

Students will work in pairs to design posters with illustrations emphasizing one or more of the electrical safety rules learned in class. Students need to label their posters with the appropriate rules or create slogans that best reflect their safety rules.

(Give students rubric before activity.)
