Essential Understanding

The student conducts classroom and outdoor investigations following home and school safety procedures and environmentally appropriate and ethical practices.

Science Background

Science Safety in Elementary Schools: BioEd Online (video) - Online presentation covering classroom safety practices, particularly during students’ science investigations. Includes information about key safety equipment and strategies for setting up a safety object wall.

Signature Lesson

Science Safety is Elementary: Ohio Department of Education (PDF) - Students discuss science safety, identify and demonstrate basic science safety procedures, and use appropriate classroom safety equipment. They will decide which of their five senses would need to be protected in different situations (personal safety) and identify precautions necessary to avoid hazards in the classroom (classroom safety).
