• Systems and System Models

• The reasons and results of something

• Energy and Matter

• Representiong how things interact

• Cause and effect

• Consistent or repeated structures/events

• Scale, Proportion, and Quantity

• Can't be created or destroyed

• Patterns

(a) Structure and Function

,

(b) Stability and Change

,

(c) Patterns

,

(d) Cause and Effect

• Birds have wings so they can fly

• Ancient fossils can be preserved in rock layers for millions of years

• Chemicals like ammonia and bleach are stable on their own but change to a poison gas if combined

• The moon has the same series of phases every 27-28 days

• When you don't wash your hands, you can get sick from germs

• Some fossils are consistently found in the same rock layers

• The structured order of rock layers in the earth acts like a timeline of their relative ages

• The Colorado River caused erosion of rock layers and made the Grand Canyon

Which idea from natural hazards does NOT represents a pattern?

• Last year, Tucson had over 66 days where the temperature was 100 degrees or more.

• A Doppler radar constantly sends out radio waves and measures them as they return to detect storms and other types of weather.

• Most volcanoes and earthquakes are found near the Ring of Fire around the Pacific Ocean.

• Hurricanes Katrina cost over $161 billion in damages.

Reorder the following events to show the cause and effect of volcanic eruption

• Volcanic clouds in the atmosphere can drift around the world and affect global weather by blocking sunlight

• Molten rock or magma is moving under the surface of the earth

• Some eruptions can be explosive, creating fiery clouds that destroy anything they fall on

• Ash falling from explosive eruptions can mix with water and create dangerous mudflows, or lahars

• Earthquakes or other disturbances cause magma to be pushed up to the surface

• We measure blizzards by how much snow falls on the ground

• Quantity

• On average, Flagstaff gets 10 times more snow as Tucson

• Proportion

• In December 1967, a blizzard snowed 84 inches on Mt Lemmon
