2.2 <strong>de</strong>scribe trends based on given graphs, and use the trends to make predictions or justify<br />

<strong>de</strong>cisions (e.g., given a graph of the men’s 100-m world record versus the year, predict the<br />

world record in the year 2050 and state your assumptions; given a graph showing the rising<br />

trend in graduation rates among Aboriginal youth, make predictions about future rates)<br />

Sample problem: Given the following graph [see page 138 of the curriculum document],<br />

<strong>de</strong>scribe the trend in Canadian greenhouse gas emissions over the time period shown.<br />

Describe some factors that may have influenced these emissions over time. Predict the<br />

emissions today, explain your prediction using the graph and possible factors, and verify<br />

using current data.<br />

Note: <strong>The</strong> sample problem illustrates how an environmental connection can be ma<strong>de</strong> in the context<br />

of this expectation – in this case, through a <strong>de</strong>tailed examination of greenhouse gas emissions.<br />
