We will kick off the year with Landforms
In this unit, we learn how to create maps and models, and we investigate erosion and deposition, and we'll discuss mountains and topographic maps.
There are FIVE investigations in this unit:
Investigation 1 - Schoolyard Model
We will create a 3-dimensional model of Jennings School, observe and compare features on models and cooresponding maps, and experience how maps can be generated from models.
Vocabulary:
model
boundary
structure
map
cartographer
grid
symbol
key
Investigation 2 - Stream Tables
We will investigate water flow over earth materials in a stream table, observe the process of erosion, deposition, and stream flow, and relate the processes they observe in the stream table to the processes that create the Grand Canyon.
Vocabulary:
drainage basin
erosion
landform
canyon
delta
plateau
deposition
sediments
basin
channel
meader
Investigation 3 - Go With The Flow
We will investigate how slope of the land affects erosion and deposition, investigate how a flood flow affects erosion and deposition, and design and conduct investigations to discover how changes humans make to stream channels affect stream processes.
Vocabulary:
slope
alluvial fan
flood
flash flood
levee
dam
floodplain
hypothesis
conclusion
observation
key
measurement
labels
Investigation 4 - Build A Mountain
We will build a foam-mountain model and compare it to a real mountain, draw a topographic map and a profile of the model mountain, and relate topographic features to symbolic representations on maps.
Vocabulary:
base
contour line
contour interval
elevation
peak
sea level
topographic map
profile
bench mark
intermitent stream
perennial stream
Investigation 5 - Bird's-Eye View
We will observe and describe the types of information on a topographic map, compare the Mt. Shasta foam model to the U.S. Geological Survey topographic map of Mt. Shasta, and interpret images on an aerial photograph and compare them to landforms found on a map.
Vocabulary:
ridge
glacier
valley
interpret
aerial photograph
scale
surveyor
bar scale
representative fraction
rapids
intermittent lake
