Fluorite (mineral) Fluorite is a common and widely distributed mineral often found in hydrothermal veins or in association with lead and silver ores. form: usually cubic or octahedral color: blue or purple texture: smooth streak: white luster: vitreous transparency: transparent to translucent hardness: 4.0 Acid reaction: not reactive

Doing Science: A Transcript of the Text-based Interface

1. Student is Assigned a Goal

You have a general goal: to 'report' all the rocks and minerals you find. You also have a specific goal: to 'report' the identity of Fluorite

Fluorite is a purple vitreous smooth-faced mineral.Fluorite is used to make flux.To see this message again, type '@showgoal' or 'showgoal'

You are standing by a large cave entrance cut into a sheer rock face.* To the South is a Deep Valley* To the Southwest are the Young Mountains* To the West is a Steep Ledge* To the Northwest is a Steep Cliff* 'Enter' will get you into the Cave.Obvious exits are: enter South Southwest West NorthwestYou see light grey compact fine-grained outcrop (#1945), purple vitreous smooth-faced vein (#1989), and yellowish brown resinous vein (#1998) here.

2. Student Navigates

Swoosh...the Rock Pick/Hammer (#2062) arcs towards the purple vitreous smooth-faced vein (#1989)A purple vitreous smooth-faced sample (#5969) appears in your inventory

hit #1989 with rock pick

pour acid on #5969

You hear the sound of pouring and ....Nothing happens

3. Student Performs Experiments

taste #5969

As the magnet approaches the purple vitreous smooth-faced sample (#5969)...Nothing happens.

touch #5969 with magnet

You put your tongue onto purple vitreous smooth-faced sample (#5969) and detect no taste

4. Student Continues Experiments

You scratch Glass Plate (#2064) with purple vitreous smooth-faced sample (#5969) ...Glass Plate (#2064) scratches purple vitreous smooth-faced sample (#5969)

scratch glass with #5969

5. Student Continues Experiments

Checking: purple vitreous smooth-faced sample (#5969) against fluorite.You are right! purple vitreous smooth-faced sample (#5969) IS fluorite.You have satisfied your primary goal! You score 100 points.

report #5969 as fluorite

6. Student Achieves Goal

Assigning new goal for session: 11/30/99 at 1:13 p.m.

As a player in the Geology Explorer You have accomplished your third goal and are playing at the advanced level. You have a general goal: to 'report' all the rocks and minerals you find. You also have a specific goal: to 'report' the identity of Potassic Feldspar Potassic Feldspar is a mineral.

Example of a ScenarioExample of a Scenario

You are in northern Manitoba on a fishing trip. Fishing has been good. At dawn on the day of your departure, you cut across country to a remote bay and have more good luck: you catch your limit of walleye.

On the way back to the lodge, you stumble across a heavy, moss-covered rock on the shoreline, flipping it over. Looking down, you see the underside of the rock shining with a brilliant metallic yellow. You pick up the rock and lug it back to the lodge.

At the airport luggage check-in, the baggage agent notes that you are 20 kg overweight . . . . . . exactly the weight of the rock that you found. He says, “It’s okay to ship rocks back to the States, eh, but at $15 per kilogram, you’re going to owe $300!”
