  • Identify and describe careers related to the fields of science under study, and describe the contributions of scientists, including Canadians, to those fields.
  • Evaluate the importance of government regulations, scientific analyses, and individual actions in
  • Improving air and water quality, and propose a personal plan of action to support these efforts.
  • Demonstrate an understanding of chemical reactions that occur in the environment as a result of both natural processes and human activities.

Work:  

  • Using the Scientific Investigation approach,  you and your partner(s) will formulate a question concerning an environmental issue.
  • Initiate and Plan - Formlate a question or hypothesis that you want to test or verify.  Identify the possible dependant, independant and control variables.  
  • Materials and Procedure and Safety Protocols:  Please have the Materials/Procedure approved by your teacher.  
  • Perform and Record Observations
  • Critically analyse and interpret your data and evaluate the reliability of your data.  Draw conclusions.  Identify sources of errors and ways to improve your experimental design. 
  • Communicate your findings using a formal lab report and presentation.
