Hold on TIGHT! The CONTINENTS ARE MOVING…
S6E5. Students will investigate the scientific view of how the earth’s surface is formed.
e. Recognize that lithospheric plates constantly move and cause major geological events on the earth’s surface.
f. Explain the effects of physical processes (plate tectonics, erosion, deposition, volcanic eruption, gravity) on geological features including oceans (composition, currents, and tides).
g. Describe how fossils show evidence of the changing surface and climate of the Earth.
Phase 1: Research the interior of Earth: Composition, temperature, density, relationship between the layers
Phase 2: Use current scientific evidence to support Alfred Wegener’s theory of continental drift.
1. PROBLEM PRESENTED:
Alfred Wegener, a meteorologist, stumbled upon a new and unexpected discovery…Earth’s continents are moving. Unfortunately, the
technology of his day (early 1900’s) wasn’t sophisticated enough to offer physical proof. He became the laughing stock to many in the world of
science. He died on an expedition doing what he loved…research! Mr. Wegener now has the last laugh, science world. Technology of the
modern world has offered physical evidence that Earth’s surface is changing and has been for years.

3. ANALYSIS OF PROBLEM (Data collection, charts/graphs, analysis):
1. You will create a diagram of Earth’s interior that compares the physical and compositional features.
2. You will examine photographs taken all over Earth that show how plate tectonics are slowing changing the surface of our planet.
3. You will research the evidence (both direct and indirect) that support Alfred Wegener’s theory of continental drift.
4. SOLUTION FORMAT:
A letter to the unbelieving science world of the early
1900’s.

7. PRESENTATION: (Rubric will be provided)
A letter will be written to the unbelieving science world of the early 1900’s in support of Alfred Wegner’s theory of continental drift. You will
use current scientific evidence to support his theory. (Wouldn’t time travel be super cool for these purposes?!)
