  9. Education Act: O. Reg. 298/Ministry of Education Office of Ontario Fire Marshal Overview of Legislation Occupational Health and Safety Act/Ministry of Labour Science Teacher Science Biology Chemistry Environmental Science Earth and Space Science Physics WHMIS/ Ministry of Labour The Environmental Protection Act

  10. Legislation related to Safety in general: Education Act: O. Reg 298, 20.(g), Duties of Teachers ‘ensure that all reasonable safety procedures are carried out in courses and activities for which the teacher is responsible’ http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900298_e.htm

  11. Legislation related to Safety in general: Occupational Health and Safety Act (OHSA) and its Regulations: • Teachers need to be aware that under the OHSA every worker has the right to know about the hazards in their workplace, to bring issues to the employer’s attention and to refuse work that is unsafe • Science teachers should have adequate training in the procedures for the safe use and handling of all chemicals used in the curriculum including flammable and combustible liquids ……. http://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_90o01_e.htm

  12. Legislation related to Safe handling ofFlammable and Combustible Liquids: - Office of the Fire Marshall (OFM): Ontario Fire Code -Sentence 4.12.4.1.(3), Division B states: "Personnel working in laboratories shall be trained in the safe handling of flammable liquids and combustible liquids“ http://www.e-laws.gov.on.ca/html/source/regs/english/2007/elaws_src_regs_r07213_e.htm • OFM guideline, ‘Handling Flammable and Combustible Liquids in School Laboratories’ http://www.ofm.gov.on.ca/en/Legislation%20Directives%20and%20Technical%20Guidelines/Technical%20Guidelines%20and%20Reports/pdf/OFM-TG-01-2011.pdf

  13. What does Curriculum Policysay about Safety in the Classroom? Implementation of the provincial Grades 9-12 Science curriculum policy requires that: ‘Teachers must model safe practices at all times and communicate safety expectations to students in accordance with school board and Ministry of Education policies and Ministry of Labour regulations’ The Ontario Curriculum, Grades 9 and 10 Science, 2008: Health and Safety in Science http://www.edu.gov.on.ca/eng/curriculum/secondary/science910curr.pdf The Ontario Curriculum, Grades 11 and 12 Science, 2008: Health and Safety in Science http://www.edu.gov.on.ca/eng/curriculum/secondary/2009science11_12.pdf

  30. 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)

Dealing with Unintended Flame

  33. 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, postlabformat • Deliver just in time instructions • Leave stock bottles in prep room • Keep work areas clean (benches, fume hood)

  34. 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 Fire Safety in the Classroom

  38. Video 5 Video 5 – Safely Synthesizing Esters

  39. Video 5 – Safely Synthesizing Esters What safety precautions are taken during this activity? Summary - Application of Knowledge

  40. 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

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

  42. Discussion Question What Grade 9 classroom activities could incorporate the [PR] expectations to the right? Video 1 – Testing for Gases

  43. 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.
