    This learning object explains the anatomical organisation of the parasympathetic division of the autonomic nervous system. This learning object is used as part of the level 1 Biological Sciences module delivered by the ...

  • Penguin Watch 

    Not available (University of Cape Town, 2011)
    This website is designed to contain up-to-date news and information about the issues facing penguins in their natural habitat, specifically the African Penguin. Penguins feed at or near the top of food chains in many ...

  • Penguins 

    Shirley, R. (Richard); Neary, T. (Time) (University of Cape Town, 2014-03)
    Richard Shirley discusses penguin tracking in South Africa, and how tracking mechanisms support research on feeding, breeding and migration patterns. Also discussed are how the miniturisation of tracking devices has ...

  • Peninsula Paddle 

    Neary, T. (Tim); Winters, K. (Kevin) (University of Cape Town, 2014-03)
    Kevin Winters speaks about the Peninsula Paddle and how the event generates interest for the preservation and conservation of waterways and rivers. Urban rivers are at risk from pollution and eutrophication due to waste ...

  • PhysCasts: 1 Dimensional Motion: A Coin in a Well 

    Cook, E. (Emily) (Swinburne Commons, 2013)
    This problem is about 1D motion. A coin is dropped into a wishing well. A noise is heard when it hits the bottom 1.8s after it is dropped. How deep is the well?

  • PhysCasts: 2D Motion: Washout! 

    Hall, B. (Brenton) (Swinburne Commons, 2014)
    This is a PhysCast on 2 dimensional motion. A raging flood has washed away a section of highway, creating a gash 1.7 meters deep. A car moving at 31 m/s goes straight over the edge. How far from the edge of the washout ...

  • PhysCasts: A Ball Bouncing Back: A Vector Calculation in 1-D 

    Rowlands, W. (Wayne) (Swinburne Commons, 2013)
