Teaching biology at an international school can produce some amazing results when it comes to defining words for homework. Often times, there is a constant typing of keys and electronic voices heard as students rush to look up words as quickly as they can in their electronic dictionaries during lecture.
We just finished a few lectures about Diffusion and Osmosis. For those non-scientist types out there, diffusion is the process by which molecules or ions travel from a gradient of high concentration to low concentration. It's a natural process that doesn't need energy. Osmosis is just a specific type of this process, dealing with water. Here are a few interesting responses on the homework I assigned:
Define Diffusion:
- "the process of diffusing or being diffused"
Define Osmosis:
- "the gradual or unconscious assimilation or adoption of ideas"
Give an example of Diffusion:
- "When the egg turn bad, you can smell it"
Classic.
In other news, our class is re-thinking the BBQ idea and possibly just getting sandwiches, chips, drinks, etc. So less work, and still pretty good. Laziness and logic win in the end.
