Fire Safety in the Classroom

Classroom Safety - Teacher and Student Responsibility

‘Teachers are also responsible for ensuring the safety of students during classroom activities and for encouraging and motivating students to assume responsibility for their own safety and the safety of others. They must also ensure that students acquire the knowledge and skills needed for safe participation in science activities.’

‘Roles and Responsibilities in the Science Program’: The Ontario Curriculum, Science, Grades 9 and 10 (2008)

Fire Safety in the Classroom

Classroom Safety • Create an atmosphere of safety• Create a safety contract (STAO has one)• Have a system in place from cradle to grave• Do a prelab, lab, postlab format• Deliver just in time instructions• Leave stock bottles in prep room• Keep work areas clean (benches, fume hood)

Fire Safety in the Classroom

Planning an Activity Consider how the activities relate to the curriculum Use the smallest possible quantity/volume of a chemical Use lower/safer concentrations of reagents Use safer alternative i.e., not flammable or combustible and less toxic Use hot plates instead of open-flame burners Use the minimum reagent temperature (10 fold increase for every 10°C change) Do the labs yourself ahead of time, consult experienced teachers

Curriculum Connections

Refer to the Curriculum Handout Strand A contains expectations describing Scientific Investigation

Skills (SIS)

Strands B-E/F contain expectations describing major topics or content areas

Strand A expectations are to be developed through instruction of the B-E/F strands, by means of hands-on student practice where appropriate (i.e., these skills are not developed in isolation)

Curriculum Connections

Four Types of SIS/Strand A Expectations IP – Initiating and Planning PR – Performing and Recording AI –Analysing and Interpreting C – Communicating

Video 1 – Testing for Gases

Discussion Question

1. What Grade 9 classroom activities could incorporate the [PR] expectations to the right?

What do Curriculum Expectations in strands B - E/F require for Scientific Investigations?

Only specific expectations with [PR] (under “Developing Skills of Investigation and Communication”) require students to perform an investigation.

Many of the specific expectations are accompanied by examples which: are meant to clarify the requirements specified in the expectation,

illustrating the kind of knowledge or skill..... are intended as suggestions for teachers rather than as

exhaustive or mandatory lists allow teachers to choose ones that are appropriate for their

classrooms and courses, or they may develop their own approaches that reflect a similar level of complexity.
