Activity Description of "Pressing Limu"
|Title ||Pressing Limu|
|Audience ||biology - all levels|
|Abstract || Limu is the Hawaiian term for algae or seaweed. All limu in Hawaii are edible but flavors and textures vary greatly.
Scientists collect and press plant specimens to use for reference and study. Scientists have a procedure for pressing and identifying plants. A collection of pressed specimens is called an herbarium.
Algae are aquatic plants, therefore, the pressing process requires that the specimens be submerged in water. Pressing and drying can be done easily, even at home with readily available resources such as newspaper, waxed paper, and several heavy books.
This activity uses the basic algae pressing techniques but, instead of selecting only one type of algae per sheet, you may create a collage of seaweeds by arranging a few different types on one sheet. This, then, can become a notecard, a paperweight, or can be framed.
