Science Project – October – OUR PLANET
Students will demonstrate their knowledge of these three scientific concepts by developing a
presentation which demonstrates the integration of how these three concepts work together on
our planet. With all projects during the year the “format” or “display” is up to the individual
student. All students must utilize the same information in their presentation.
One key fact: See IT (what does it look like)…
Explain IT (how does it work)…
Create IT (how will I show it)…
Rock Cycle
Igneous - intrusive
-extrusive
sedimentary
metamorphic
Rocks are classified as igneous, sedimentary and metamorphic.
Weathering breaks rocks down into smaller pieces called sediments.
Igneous rocks are rocks formed from the crystallization of magma
Extrusive igneous rocks cool at the earth’s surface.
Magma that reaches the earth’s surface is called lava.
Sedimentary rocks are rocks formed from the sediments of weathered rocks.
Metamorphic rocks are rocks formed from the chemical restructuring of a rock due to hear
and pressure.
Layers of the Earth
inner core
outer core
mantle
crust - oceanic
continental
The three layers of the earth are the curst, mantle and core.
The crust is divided into two types, continental and oceanic.
Continental crust is composed of mostly granite.
Oceanic crust is composed of mostly basalt.
The mantle is divided into upper and lower.
The core is divided into the outer and inner.
The outer core is liquid and composed of nickel and iron.
The inner core is solid due to extreme pressure and is composed of nickel and iron.

Plate Tectonics
Divergent
Convergent
Transform –Fault
The theory of plate tectonics states that the earths crust is broken into plates that float on the
surface of the mantle.
Convection currents in the mantle cause the plate movements.
The plate movements are responsible for the formation of mountains and oceans.
The three types of plate boundaries are places where plates move toward one another.
Divergent boundaries are places where plates move away from each other perpendicular to
the line between the plates.
Transform-fault boundaries are places where plates slide past each other parallel to the line
between the plates.
Sea=floor spreading occurs at divergent boundaries in the ocean
Ideas to help get you started!
Lots of different power point presentations to watch!
