Initiating and Planning:  formulate questions about observed relationships; plan investigations of questions, ideas, problems and issues •  state hypotheses and make predictions based on information about the pressure, temperature and volume of a gas (IP-NS3)  • describe procedures for the safe handling, storage and disposal of materials used in the laboratory, with reference to WHMIS and consumer product labelling information (IP-NS4)  • design an experiment to illustrate Boyle's and/or Charles's gas laws (IP-NS2)  • design an investigation to determine the universal gas constant (R) or absolute zero (IP-NS2)  • explore how people who are connected with the land, such as Aboriginal peoples and agricultural workers, have used plant and animal responses to changes in atmospheric pressure as indicators of changing weather (IP-NS1)
