30-A1.2s

Performing and Recording:  Students will conduct investigations into relationships between and among observable variables and use a broad range of tools and techniques to gather and record data and information;    • design and perform an experiment to investigate the physiology of reflex arcs (IP-NS2)(PR-NS2)(PR-NS3)(PR-NS4)[ICT F1-4.2]      • perform experiments to measure the ability to discriminate objects visually and to hear a range of sounds (PR-NS2)(PR-NS3)(PR-NS4)      • use a microscope and prepared slides to observe neurons and synapses (PR-NS2)(PR-NS3)(PR-NS4)       • observe the principal features of a mammalian brain, eye and ear, using models, computer simulations or dissections, and identify the major structures of those organs (PR-NS3)(PR-NS4)[ICT C6-4.4]       e.g. •  investigate and integrate, from library and electronic sources, information on the impact of photoperiod and wavelength on humans (PR-NS1)(PR-NS4)[ICT C1-4.1]      • compile and display, in appropriate format, data collected from investigations on reflex arcs, stimulus strength versus force of muscle contraction, and/or auditory range (PR-NS4)[ICT P2-4.1]
