Lesson 2

What would we normally expect for these places and how do we know it's really changing?

Lesson Objectives...

Develop and use a model to describe the components, interactions, and processes of water distribution and movement on Earth.
Use graphical displays (e.g., maps, charts, graphs, and/or tables) of large data sets to identify temporal patterns in temperature, total precipitation, and seasonal precipitation in the local community and at case sites.
Analyze and interpret data about patterns in rates of change and numerical relationships to determine similarities and differences between drought and flood sites.

Investigating Cases in the US - Storymap

The image to the right is a link to the StoryMap we will be using to dig a little deeper in to your assigned location. The videos you are to watch will not work in the StoryMap so the videos are embedded in this site below. Watch the videos and analyze the data to gather evidence to help you figure out what might be causing floods or droughts in these areas.

What we figured out this lesson...

Earth's freshwater is distributed in the air, at the ground, and below the ground and moves in between these spaces.
Year-to-year variability in precipitation and temperature is a normal pattern.
Data averaged over long periods of time can give us the trends for an area.
Precipitation or heavy storm events show increasing trends in flood areas.
Precipitation, groundwater, and snowpack show decreasing trends in drought areas.
Temperatures are increasing for all of the places we investigated.
