Follow ALL instructions PRECISELY
Put a single charcoal briquette in a cup you form around your fist made of aluminum foil. Use a strip of paper inserted in the last fold of the aluminimum foil to lable your experiment with your name & class period. Use a plastic container to mix this list of ingredients together, & stir until solids appear mostly dissolved:

• 10 grams table salt (NaCl - Halite)
• 12ml laundry bluing
• 12ml H2O
• 5ml household ammonia (NH4)
• charcoal briquette
• aluminum pan, cupcake cup, or foil formed cup

Use the provided graduated cylinders & balances in the lab. You can't mix this partially and finish another class & have it work! Store your experiment in one of the grey trays under the cabinets along the sides of the room (under the windows and glass cabinets - the trays under the presentatiuon screen are for my yse alone - I store geology examples there).

Pour the dissolved solution over the briquette, making sure at least some portion remains above the final level of the solution in the container.
Observe & record results in terms of WET or DRYconditions in the bowl, WHERE the growth occurs in terms of substrate (paper, aluminum, charcoal, salt), and the COLOR of the substrate (yellow, brown, green, blue, or no color over the material the crystals are growing out of). All crystals will be too small to indicate color themselves, but their aggregate (large clumps) will show the individual crystal shapes.

Be sure to label your experiment clearly with your name and period, and be aware that no one can be responsible for its success or condition! - it's an experiment! Describe the crystal shapes using a hand magnifier, loupe, document camera, or microscope. I'll demo for each class how to use the computer microscope SAFELY without risking its optics.

ID your crystal shapes using loupes, document camera, or video microscope by trapping an aggregate example from 3 different growth regions between the sticty sides of clear tape. Retain the samples in your journal, labled by their location (blue aluminum, plain charcoal, etc.). They get attached to your report in the data section, with crystal shapes you observed added to the growth location. You state your best guess as to their mineral ID backed by your growth area and crystal shape evidence in the conclusion section.

Tape & seal 2 different samples (color+carbon, plain carbon, colored aluminum, plain aluminum) for me to examine to verify your reported findings & turn it in taped to your paper.

Available TWICE - (1/4 lab credit each after completion of both mineral project components above) for self-guided crystal growth activity, with instructor's approval for an extra 10 project points each. Chose one manipulated variable from the above recipe each time.
