The significance of race and ethnicity in the separation amongst individuals during the years of apartheid. Posted by Sikhanyisiwe Mkhonto Race and Ethnicity are terms that are used interchangeably by the society. Studies have been conducted in trying to find ways to define these terms. Race is a term that has a variety of meanings attached to it. However, the main idea of it all is that this word categorises people into groups that share a historical origin, characteristics and physical traits (MacEachern, 2012: 34-35). Ethnicity means collective identity. This implies that individuals share a tradition that help shape their culture, plays a role in identifying themselves and distinguishes them from other ethnic groups. For example, an ethnic group have the same language in which they communicate in, they share similar ways of dressing, eating and even celebrating. One could be of the same ethnic group; however, their skin colours differ (Antweiler, 2015: 26). In this essay ...
Topics Ideal Gas Law Kinetic Molecular Theory Diffusion PV Work Maxwell-Boltzmann Distribution Description Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles. Explore diffusion and determine how concentration, temperature, mass, and radius affect the rate of diffusion. Sample Learning Goals Determine how changing a variable among P, V, N, and T influences other gas properties. Describe the relationship between particle-wall collisions and pressure. Predict how changing temperature will affect the speed of molecules. Predict the speed of molecules in thermal equilibrium based on the relative masses of molecules. Identify when pressure-volume work is done on ...
Why liminal spaces are uncertain and ambiguous and promote a feeling of communitas amongst the people who occupy these spaces. Posted by Sikhanyisiwe Mkhonto We are constantly moving from one space to another. These are often large socially constructed spaces that create meanings or serve a function in our society. There are however spaces where we are neither in nor out. This space is the centre of two large spaces. A small space where one feels connected with the fellow members who are occupying that small space in that moment (Shortt, 2015: 634). Turner investigated the works of Arnold Van Gepp who spoke of the concept of ‘rite de passage.’ Victor Turner’s focus was the liminal period of a ritual. ‘Liminality is ambiguous, this is because the individual is not being classified into any category which confirms their role in a cultural society’ (Turner, 1969: 95). In this liminal period members involved experience a sense of harmony, this is what Turner labels as communit...
Unitut lite is a small/convenient app from unitut, it focuses more on the core features of unitut. It is primarily made to be used when users are specifically looking for a small sized app with better performance and offline support. It is still under development but expected to be released late this year.
Topics Interference Double Slit Diffraction Waves Description Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures. Sample Learning Goals Make waves with water, sound, and light and see how they are related. Design an experiment to measure the speed of the wave. Create an interference pattern with two sources, and determine the ways to change the pattern. Find points of constructive and destructive interference by eye and by using the detectors. Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern? For light, predict the locations of the fringes that appear on the screen using d sin(θ) = mλ. Use the tape measure to verify your predictions. Explain how the aperture geo...
Topics Ohm's Law Circuits Current Resistance Voltage Description See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. Sample Learning Goals Predict how current will change when resistance of the circuit is fixed and voltage is varied. Predict how current will change when voltage of the circuit is fixed and resistance is varied.
