The cogs are turning…

Ahh, a sight to gladden a teacher’s heart! You can positively feel the brain-power at work! The scientists in Room 1 were trying to formalize their thinking on how light refracts – one of the four boundary behaviours of light we’ve studied this term.

In order to write a good conclusion one must:

  1. Refer to the hypothesis, either confirming one’s thinking or changing it.
  2. Refer to the variables: very often, the way we know what we’ve tested is by looking at what we know we didn’t In later years the students will refer only to the independent and  dependent variables, but for now, referring to the controlled ones also helps establish what we’ve learnt.
  3. Refer to the data. You’d be surprised at how reluctant some students are to turn back a page and look at the data collected in order to confirm their thinking! But it really is vital to look at results in order to confirm one’s thinking.
  4. Use key words. In this case the key words were refract/refraction, bends, water, coin, and the types of controlled variables for this experiment.
