Tasks to be completed:

1. Complete “The Origins of the First Seventy Feet – Well Watch Testing Sites”
2. Complete the Geological Layers of the Front Range drawing

Materials:

• Blank sheet of paper
• Writing utensil
• Soil sample 2A (from bag #2)
• Soil sample 2B (from bag #2)
• Hand Lenses
• Shale rock (recommended)
• Pipette
• Water
• Presentation Talking Points (recommended for note-taking)

Vocabulary:

• Aquifer – an underground layer where the material contains water.
• Basin – any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water.
• Cirque – amphitheatre-like valley formed by glacial erosion.
• Glacial Lake – A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land, and then melts, filling the depression created by the glacier.
• Moraine – any glacially formed accumulation of unconsolidated glacial debris that occurs in both currently and formerly glaciated regions on Earth.
• Groundwater – water held underground in the soil or in pores and crevices in rock.
• Infiltration – the process by which water on the ground surface enters the soil.
• Lateral moraine – parallel ridges of debris deposited along the sides of a glacier.
• Permeability – defines how easily a fluid flows through a porous material.
• Pore space – spaces between the sediments where water or air can flow.
• Subduction zone – geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle.
• Terminal moraine – also called end moraine, is a type of moraine that forms at the snout of a glacier, marking its maximum advance.
