  1. “The Great Crystal Creation” - Friday Feedback Session Team Leader: Kendra Mallory Team Members: Stephen Ha Winnie Koo Stacy Woodson Margaret Rockwood Syed Warisi This material is based upon work supported by the National Science Foundation under grant No. EEC-0502174. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.

  2. Module Enhancements • Try different types of crystal formation using baking soda, kosher salt, rock salt, brown sugar, and so forth. • Relate real world objects to crystal shapes. • Discussion of different types of chemical bond. • Relate crystals to minerals.

  3. Engineering Design • Design ways to make improvement on existing architectural structures based on the seven shapes of crystal. • Design a better classification system on minerals and rocks based on the seven shapes of crystal.

  4. Scientific Inquiry • What variables affect the hardness, shape, and color of a crystal? • What condition affect the quality of a crystal? • What variables affect the rate of the formation of a crystal?

  5. Ethics • Instant gratification vs. delayed gratification. • The importance of following health and safety instructions. - Always have supervision. - Pay attention to safe usage of chemicals. - Follow warning and caution signs.

  6. Modification 1 • Age Group: Elementary • Engineering Design - Design objects based on the seven shapes of crystal as well as other geometric shapes. • Scientific Inquiry - Identify repeated patterns in nature. • Ethics - Safety such as material handling, no drinking and eating, and so forth.

  7. Modification 2 • Age Group: High School • Engineering Design - Design a system to analyze fake diamonds from natural real diamonds. • Scientific Inquiry - Discussion on molecular structures. • Ethics - Authenticity of diamonds.
