Lesson Plan

“Population Explosion”                Don't Let It Loose: 5-8th Grade

Students in a meadow


Students will be able to  recognize melaleuca and tell how the seeds are dispersed. They will describe that melaleuca produces over 1 million seeds per year and have a concept of how much that really is. Students will determine the population of melaleuca seeds for their wetland ecosystem through sampling.


Our "Don't let it Loose" unit is broken into seven lesson plans, each taking 45 minutes to 4 classroom periods to complete, and targeted primarily at middle school students. A class needn't complete every lesson in the unit, though some lessons do refer to one another. However, each lesson comes with its own set of objectives and resources.
