List of Key Term definitions

  1. Sense key term.

    1. Sense

    A means of receiving and interpreting external stimuli by the brain. The stimuli can be perceived by special sensory cells in the body. This process may involve the senses of hearing, sight, smell, taste and touch.

  2. Sensor key term.

    2. Sensor

    An electrical device for gathering information, such as data about movement, temperature, light, sound and so on.

  3. Robot key term.

    3. Robot

    An electrical and mechanical machine that is programmed electronically to do specific tasks. It may have sensors to perceive and process data and to respond to different stimuli. It can have different degrees of being autonomous or self-controlled.

  4. Electricity key term.

    4. Electricity

    A general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge.

  5. Electronic key term.

    5. Electronic

    Relating to electrical devices that work by controlling the flow of electrons especially using semiconductors.

  6. Battery key term.

    6. Battery

    More than one electrical cell connected together. It stores chemical energy that can be converted into electrical energy.

  7. Electrical circuit key term.

    7. Electrical circuit

    A complete route that electrons can follow. Unless there is at least one complete path, no electric charges will flow. A circuit usually consists of a power source, other electrical components and an unbroken pathway for the conduction of electricity.

  8. Conductor key term.

    8. Conductor

    A material that has low resistance and allows electric current to travel through. Conductors are used to make wires and electronic components. Examples are carbon and metals such as copper.

  9. Semiconductor key term.

    9. Semiconductor

    Material that has conductive properties that are between good conductors and insulators. Semiconductor devices have low resistances when a certain voltage is placed across them. At this voltage, they begin to conduct electricity easily.

  10. Resistance key term.

    10. Resistance

    A measure of the difficulty for electric charges to flow through a substance. Conductors have low resistances, insulators have very high resistances and semiconductor devices have resistances that drop when a certain voltage is across them. The changing resistance of a component is put to use in some devices, for example, thermistors change their resistance with temperature.

Science Learning Hub Survey 2014

Dear Hub visitor,

You're invited to participate in an online survey about the New Zealand Science Learning Hub. This survey was designed to help Hub staff enhance and develop further the site. This is different from our November 2013 survey, so even if you took part in that survey, we would appreciate you taking this survey as well.
