We had to present our work to the class. Li Shan's group went first. They were supposed to measure the approximate amount of water in Mac Ritchie Reservoir based on the map and the fact that the reservoir was 5 m deep.
They certainly thought through their scenario very well. The group gave two possible solutions. The first was to use the scale to calcuate the length and width of the reservoir, then multiply it by the depth for the final answer. The second was to draw the shape of a cylinder on the map. The cylider covered most of the reservoir. After that, they used a formula to calculate the volume of the cylinder and used the scale to convert it to live size. I found the presentation clear, concise, well-thought and interesting.
It was our turn next. I think we did okay. At least no one seemed confused when we explained our method.
We were supposed to finish off all the group presentations, but we were running late again.
