This lesson teaches students about ecological succession. The lesson begins by defining the difference between primary and secondary succession. Students are then told that secondary succession is a way for an ecosystem to “heal” after a disaster. This is compared to a scab helping a cut to heal. Students then examine “ecological succession” in an urban neighborhood that has been taken over by criminals. (This activity really helps students who may have less experience in nature.) Students only then are asked how a forest might heal after a fire. All three of these examples include pictures and powerpoint slides.
The concepts are reinforced with an online activity that has animations of both primary and secondary succession. Finally, the lesson includes a worksheet wherein students examine ecological succession in a pond. (I usually assign this as homework.)
