Big Ideas About Earth and Space
Earth is a
dynamic
system.
Earth is a
planet in
Space.
Earth history is
recorded in
rocks
Earth is a Dynamic Interacting System
A core concept at the middle
and school level concerns the
important concept of plate
tectonics—that Earth’s crust
consists of huge plates whose
interactions cause earthquakes
and volcanoes.
Earth’s History is Recorded in Rocks
A major revolution in Earth
science and biology of the 19th
century is that fossils are the
remains of life forms that
existed long ago. Fossils buried
more deeply in sediments are
older than fossils in shallower
sediments.

Earth is a Planet in Space
A major revolution in Earth
science that occurred more
than 2,000 years ago, in
ancient Greece is that our
planet Earth is a huge ball in
space.

Our Students’ Ideas
One of our jobs as educators is
to understand our students’
current mental models, to
unravel any misconceptions
they may have, and help them
acquire the really big ideas
about our planet in space.

“Why does Earth look
flat if it’s supposed to
be round?”
Understanding Our Students Mental Models
How do stories like “The Goldilocks Effect”
help to communicate the big ideas about
Earth and space?
How do activities like “Planets, Climate, and
Life” help you understand your students’
current ideas about Earth and space??
