- Grow our own crystals for a permanent collection from some of the following: ALUM, SALT, SUGAR, BORAX, ROCHELLE SALT (or others). Grow at least four different crystals.
- Learn to spell and define:
- Efflorescent c. Piezoelectric
- Deliquescent d. Refraction
- Spell, define, and memorize the six systems of symmetry.
- Make a collection of at least 10 crystals made by nature. (Examples: quartz, iron pyrite, natural ruby, and other gemstones.)
- 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.
- 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.
- State at least five consumer items that require the use of crystals or are crystals in useable form.
