Having recently completed the energy rotations into other classrooms to learn all about the different sources of energy, it’s now time to sit back and think about them. Using “talk sticks”, we chatted in groups of 3 about what was the “best” energy source and why. Then we spent 2 days working in small groups on an evaluating and ranking activity to get our minds thinking about weighing up both the good and the bad. Each group  was given a booklet that had a page of statements, one for each energy source… wind, solar, geothermal, biomass, coal, petroleum oil, coal and uranium. It was the groups’ job to first read each statement and decide whether it was a fact, advantage OR a disadvantage. The next step was to then go through each advantage and disadvantage to decide where the group felt sat on the continuum from -3, -2, -1, 0, +1, +2, +3. This lead to some really good discussions about “how bad or how good” a statement was. For example, with solar… “solar energy is a renewable energy source. We will have it as long as the sun shines” vs. “the sun’s energy is spread out and hard to capture. The energy is only available when the sun is shining, not 24 hours a day.” Would you give the first one a +2 or a +3… would you give the second one a -3 or a -1??? Then the students brought their results up to a central “class results tally sheet”. With support, we then calculated the average ranking for the entire class to compare to what our group had! It was a challenge, but a good challenge, to think about as we head deeper and further into our energy unit!!
