Performing and Recording:  conduct investigations into relationships among observable variables and use a broad range of tools and techniques to gather and record data and information  •  perform an experiment, in which variables are identified and controlled, to illustrate gas laws (PR-NS3)(PR-NS5)[ICT C6-4.2][ICT F1-4.2]  • use thermometers, balances and other measuring devices effectively to collect data on gases (PR-NS3)[ICT F1-4.2]  • use library and electronic research tools to collect information on real and ideal gases and on applications of gases, such as hot air and weather balloons (PR-NS1)[ICT C1-4.1][ICT C1-4.2]  •perform an investigation to determine molar mass from gaseous volume (PR-NS3)(AI-NS6)[ICT C6-4.2]
