1. Grow your own crystals for a permanent collections from some of the following: ALUM, SALT, SUGAR, BORAX, ROCHELLE SALT (or others). Grow at least four different crystals.
2. Learn to spell and define:
- a. Efflorescent
- b. Deliquescent
- c. Piezoelectric
- d. Refraction
3. Spell, define, and memorize the six systems of symmetry.
4. Make a collection of at least 10 crystals made by nature. (Examples: quartz, iron pyrite, natural ruby, and other gemstones)
5. To show a useful electrical trait of crystals, grow a Rochelle salt crystal at least two inches thick and conduct an experiment to show the piezoelectric effect to the satisfaction of your instructor.
6. To show a useful optical trait of crystals, grow a sodium nitrate crystal at least two inches wide and demonstrate the phenomena of double refraction to the satisfaction of your instructor.
7. State at least five consumer items that require the use of crystals or are crystals in usable form.
