CLIMATE CHANGE: ORGANISMS AS CLIMATE INDICATORS

Kit #481E — Developed by EDC

In this activity students examine simulated drill cores of recent and much older seafloor sediments
that contain “fossils” of microscopic organisms called foraminifera (forams) . Students sort the different
forams contained in their sediment core and determine the percentage of a certain species with right-
coiling shells . Knowing the age of the sediments and that the percentage of right-coiling shells correlates
to the water temperature at the time, students create a graph showing how water temperature has
changed over time .
Kit does not include the actual sediments that form the matrix surrounding the “fossils .”
Use your own or those in EDCE-B013, chosen to reduce “fossil” damage .
Accommodates unlimited classes, each with 16 groups of two students.

EXAMINING FOSSILS

Kit #406S — Developed by SEPUP
Fossils provide important evidence about changes on Earth .
This kit provides students with the opportunity to handle
and examine eight different fossils from various localities and
geologic ages . Fossils of species that are no longer living,
as well as fossils of species similar but not identical to those
alive today, provide evidence for extinction and evolutionary
change. Students experience first-hand the power and
limitations of using fossils as evidence of past life and as one
of the bases for determining evolutionary relationships . The
geologic time scale is also introduced .
Accommodates unlimited classes, each with 16 groups of two
students.
