Experimenting with Duckweed

September 22, 2017

Currently in seventh grade science, students are observing and experimenting with lemna monor also known as Duckweed.  Duckweed is a small flowering aquatic plant that is native to this area, it is found in slow or still bodies of freshwater all over Nebraska and most of the United States. It is a fast growing plant that works well for experiments because of its resilience to changing in water quality and other disturbances. Although duckweeds can set seed and produce fruit like other flowering plants, they mostly reproduce vegetatively. Meaning that like many grasses and strawberries, it reproduces by a process by which new organisms arise without production of seeds. The seventh grade students have been counting the number of fronds (leaves) and making other observations as to how their duckweed plants are growing.
