Landscapes: Vermiculture in the Classroom |
5th Grade:
Vermiculture in the Classroom
Learning Landscapes staff
meets with students to discuss what vermiculture
is, why red wiggler worms are used and not other
types of worms. Each child is given a plate with
compost and worms on it to look at under hand
lenses/microscopes. The students then separate
the worms from the compost and weigh the worms.
The worms are also weighed all together before
they are added to the worm bin. Students learn
how to maintain a healthy worm bin, what they
eat and how much to feed them. The class
receives a journal to record information about
the type of food they feed, the quantity of food
and the condition of the worm bin. At the end of
the school year the students will disassemble
their worm bin and conclude their vermiculture
project. Students separate worms from castings
and weigh each to determine amount of castings
produced and any changes in population size
Students use the castings from their bin to
fertilize one of two containers of flowers
outside the 5th grade hallway.
Students should periodically observe the plant
growth in each container and note any
differences between the fertilized and
non-fertilized plants. Labels to identify
experiment are laminated and used for visitors
to understand the program.
