(I JUST NEED THE DATA DRAWINGS AND THE DIAGRAM DRAWINGS) Model a low-gradient, low-velocity stream.

Read the scenario.

You are on a research trip to observe pronghorn in the prairie grasslands of Colorado. As you observe a herd grazing next to a nearby stream, you notice storm clouds moving in overhead and feel rain beginning to fall. How does the stream act right now upon the objects in it?

Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area.

If all your descriptions are correct, proceed to step f.

If your descriptions are not all correct, analyze the scenario again and correct your descriptions. Click on the “Check” button. Do this step until all descriptions are correct. Then proceed to step f.

Observe what happens to the sand and pebbles in the stream.

When ready, press the “Pause” button and write your observations in the space below Low-Gradient, Low-Velocity Stream in the Data section of this guide.

Draw what you see in Table A.

Proceed to the next activity.

Model a low-gradient, high-velocity stream.

Read the scenario.

As you continue to observe the pronghorn herd, the rainfall gradually increases until it is falling at a steady pace, causing the stream to flow more quickly. How does the stream act right now upon the objects in it?

Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area.

If all your descriptions are correct, proceed to step f.

Observe what happens to the sand and pebbles in the stream. Compare the erosion of sediment in this scenario and the erosion of sediment in the Low-Gradient, Low-Velocity Stream scenario.

When ready, press the “Pause” button and write your observations in the space below Low-Gradient, High-Velocity Stream in the Data section of this guide.

Draw what you see in Table B in the Data section of this guide.

Proceed to the next activity.

Model a high-gradient, low-velocity stream.

Read the scenario.

You make a second research trip to observe pronghorn in the Colorado Rockies. You are next to a steadily flowing river, observing a local herd, when you start to feel raindrops fall from overhead. How does the river act right now upon the objects in it?

Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area.

If all your descriptions are correct, proceed to step f.

Observe what happens to the sand, pebbles, and rocks in the stream. Compare the erosion of sediment in this scenario and the erosion of sediment in the Low-Gradient, Low-Velocity Stream scenario.

write your observations in the space below High-Gradient, Low-Velocity Stream in the Data section of this guide.

Draw what you see in Table С in the Data section of this guide.

Model a high-gradient, high-velocity stream.

Read the scenario.

As you continue to observe the pronghorn herd, the storm overhead gradually grows and the rainfall becomes a steady flow, increasing the speed of the river. How does the river act right now upon the objects in it?

Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area.

On the left panel, choose the description for each parameter that would correctly model the scenario.

If all your descriptions are correct, proceed to step f.

Observe what happens to the sand, pebbles, and rocks in the stream. Compare the erosion of sediment in this scenario and the erosion of sediment in the High-Gradient, Low-Velocity Stream scenario.

Draw what you see in Table D in the Data section of this guide.

Model a low-gradient, high-volume stream. Read the scenario.

You make a third and final research trip to observe pronghorn in the flatlands. While making your observations, you are caught in a downpour. You hurry away from the nearby river to seek shelter. What will happen to the flow of water in the river, and how will the river act upon the objects in it?

Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area.

On the left panel, choose the description for each parameter that would correctly model the scenario.

If all your descriptions are correct, proceed to step f.

If your descriptions are not all correct, analyze the scenario again and correct your descriptions. Click on the “Check” button. Do this step until all descriptions are correct. Then proceed to step f.

Observe what happens to the sand, pebbles, and rocks in the stream. Compare the erosion of sediment in this scenario and the erosion of sediment in the Low-Gradient, Low-Velocity Stream scenario.

Draw what you see in Table E in the Data section of this guide.
