The document discusses using a KWL chart to help understand a text about seeds of change. It explains how to fill out the K (what is already known), W (what wants to be known), and L (what is learned) columns of the chart. The K section notes plants in the US are known. The W section asks why David Fairchild brought 30,000 plants to the US. The text is then read, answering that Fairchild hoped new plants could be used as food and materials.
