Students will determine difference in temperature of air and soil in three
different locations by using a thermometer and record observations relating to
difference at each site.
A better understanding of ecosystem can be initiated early through simple tasks
which, at the same time, teach students skills in measurement, observation, and
analysis. Why things grow in one place and not in another can also be equated
with why people live in some areas and not in others as a simple environmental
Worksheet and pencil
This activity may be performed either in areas on the school playground or while
on a class field trip to the beach, rain forest, farming area, or mountain side.
The students will select three divergent soil pit areas to examine. They will
record information relative to these three areas on their "Soil Parameters
SOIL PARATERS WORKSHEET
Select three divergent soil pit areas. Dig a hole about four inches deep at
each area. Carefully place a thermometer in the soil pit bottom, cover with
loose dirt; wait about 3-5 minutes.
1.Record soil temperature.
2.Record air temperature above pit.
3.Describe plants in pit area.
4.Describe soil color.
5.Describe soil moisture.
6.Describe soil texture.
7.Describe type of material in soil (litter, duff, humus, clay)
8. Conclusions: How do pit areas #1, #2, and #3 differ? Why?
9. If the pit areas were actually large tracts of land, in which areas would
people likely live? Why?
Litter- Identifiable dead things
Duff- Partially decomposed organic matter
Humus- Completely decomposed; unidentifiable
