How to introduce all the classifications to elem students.
Bacteria, - grow some in a petri dish.
Archaea - The web site says "Archaea were initially discovered in extreme,
inhospitable environments like hot springs and deep-sea hydrothermal vents.
We now know they occur in a diversity of environments, including cow guts,
where they produce methane, and many aquatic ecosystems." So all I can
think of is to show a video about these 3 places and say they exist.
And Eukarya. : plants, - this one is easy, they already have it all around
Animals,- this one is easy, they already have it all around them
Fungi --pick mushrooms, and watch Magic School Bus video on ROT
Protists. - The web site says "Animal-like protists include some well-known
species. Paramecia and amoeba are frequently used examples of single-celled
organisms. Malaria, a world-wide disease occurring in tropical climates, is
caused by an animal-like protist, the Plasmodium. In the ocean, many
plant-like protists live at the surface where they perform photosynthesis.
. . . The fungus-like protists are commonly known as slime molds, and
include the brightly colored organisms found growing on decomposing trees
and the pesky mildew growing in a bathroom."
So have them clean the bathroom!, perhaps videos also of these things would
help. Find some slime mold on a dead tree and show it.
