Bell RingerList 2 landforms we discussed

yesterday.

I can describe where a river begins.I can name the watershed in which I live. I can describe how a watershed works.

• Recall yesterday • We used the Frayer vocabulary model

to discover our definition for landform.

• We jogged your memory using the KWL chart.

• Today we continue with landforms (list next slide)

• Page 240-241 in your text

Next ProjectDesign and make a watershed!

• 12-16-09 *DUE DATE* Individual or group

• 12-02-09 Paper work for your watershed. (instructions, rubric (how you will be graded, hints on materials)

• 12-04-09 Diagram of your watershed! • 12-08-09 Written description (How will

you make your water shed?)

Where do rivers all begin? • Runoff-

– Rain (some evaporates immediately, some soaks into the soil, the remaining flows over the ground surface)

– Snow melting– Ice melting

What affects runoff?

• 1. the type of ground surface• 2. the rate of rainfall• 3. the slope of the land

• What do all of these photo’s have in common?

All of the water is running downhill.

Let’s start small • Tributaries—are the smaller streams and

rivers that feed into a larger river.

• River systems—a river and all its tributaries together make up a river system. – Flow downhill to the pull of gravity

• Think about a bathtub

• Where does the water go when you pull the plug???

• Watershed– also called a drainage basin.
