Directions for
Construction of Simulated Landfill
In the container have
students layer in order the following materials:
plastic (to simulate
the liner in a sanitary landfill
10 cm sand or gravel
(to absorb moisture)
a thin (2cm) layer
of moist charcoal (to prevent odors)
10 cm soil
Layer the
combination of organic/inorganic materials (make two parallel sections of materials by
placing organic materials on one half and inorganic materials on the other).
5 cm soil
Layer the
combination of organic/inorganic materials (make two parallel sections of materials by
placing organic materials on one half and inorganic materials on the other).
2 cm soil
With toothpicks mark
the location of the buried objects.
Have students date
their worksheets and note the objects they buried.
To simulate the
conditions of a real landfill, it is important to press or pack each layer down
firmly and to eliminate all empty spaces within the layers.
Keep the simulated
landfill in a sunny place and water as needed to keep the soil moist.
