This resource is inspired by marine research instruments used on RV Investigator. Students will create a tool to test conductivity of different materials and investigate how coding can be used to test conductivity.
Lloyd Godson, Hastings Secondary College, New South Wales
|Nature of the inquiry problem||
How electrically conductive or insulative are different materials?
|Suitable year levels and subject areas||
Year 6 Science
Year 6 Digital Technologies
Digital Technologies Knowledge and Understanding
Students will learn about the CTD rosette system, an instrument on RV Investigator used to collect data on oceanographic parameters.
Students will learn that sea water is an excellent conductor of electricity, and marine vessels need protective coatings to prevent electronic equipment from short circuiting. Students will test the conductivity of a variety of materials using simple circuits.
|Student Learning Outcomes*||
Students will be able to:
Informal reflection questions to gauge student understanding of electrical conductivity.
|Information and communications technology (ICT)||
Computer/laptop, Light bulb / buzzer, MaKey MaKey board and USB cable, MaKey MaKey Piano Program, Alligator Clips, Beakers or cups, salt.
Objects to test conductivity - fruit, paper clip, paper, pencil, cups of distilled, tap and salt water, food, clay, copper tape, aluminium foil, plants, magnets.
