  Psychology

  Narrator:

  Listen to part of a lecture in an educational psychology class.

  Professor:

  Some of you may have heard about learning styles, the idea that there are different ways to teach or learn a material, new information, and these are not equally effective for every learner. Different learners prefer different ways of learning. For examples, a visual learner might want to see the vocabulary words written down or be shown a picture or a chart. An auditory learner would want to hear the new word being used. A kinesthetic, or physical learner, would prefer to physically interact with the material in some way like maybe moving around a set of cards with new vocabulary words written on them. And from this idea of learning style, something called the meshing hypothesis has developed.

  Chemistry

  Narrator:

  Listen to part of a lecture in a Chemistry Class

  Lecturer:

  Of course, everyone here knows you can use a microwave oven to reheat liquids or food. Basically, microwaves produced by the oven - uh - excite molecules in the food. Especially water molecules. And - when these molecules vibrate more and more energetically and bump into the molecules all around them, the heat that’s produced will eventually warm the food. But, before you all begin your next set of experiments using microwave ovens, you also need to understand, that using microwave to heat liquids can be quite different from heating liquids in a metal pot on the stove. In a metal pot on the stove, when the liquid reaches its boiling point, it begins to boil. Bubbles of water vapour rise up to the water’s surface and pop as a result of a process called nucleation. What happens with nucleation is, you start with tiny bubbles in a liquid, and then, when you increase the temperature of the liquid to the boiling point, the liquid around the bubbles starts evaporating, turning into vapour, and moving into the bubble. As the amount of vapour in the bubbles increases, the bubbles begin to grow, slowly at first, then faster and faster, and then they rise to the surface, and pop. Okay, but where do those tiny bubbles come from in the first place, so that nucleation can begin? Well, most metal pots are not totally smooth inside. They have a lot of tiny scratches and dents. And when you pour water into a pot, the water doesn’t completely fill those scratches and dents, so air gets trapped in there and forms those tiny bubbles. Then, when you apply heat, and the water gets hot enough to boil, those bubbles will lucreate as I just described. And, once the water begins to boil, if you keep adding heat, you’ll increase the rate of evaporation, the boiling, but...
