Sunscreens   
(Interactive Simulation (1))
Reinforcing the "Heath and Wellness" theme of National Chemistry Week 2004, the featured molecules for this month are all found in commercial sunscreens, or in the synthesis of sunscreen materials. The paper by Stabile and Dicks introduces students of organic chemistry to the synthesis of cinnamate esters used in sunscreen products. Several of the papers referenced by those authors, most notably a paper by Doris Kimbrough (J. Chem. Educ. 1997, 74, 51?53), present the structures of additional sunscreen components. Although the details of the synthesis are beyond the scope of most introductory courses, these molecules present an excellent opportunity for introducing students to the absorption of radiation that is far more relevant to their lives than the line spectra of hydrogen and other atoms. Such a discussion could be extended to include more delocalized dyes such as those frequently studied in physical chemistry courses as a test of particle-in-a-box models, and students could be asked about those molecules as sunscreens, which raises an interesting intersection between aesthetics and spectroscopy.

Characteristics of Materials   
(Activity, Instructional Material (7), Test, Assessment Material (15))
What makes diapers absorbent? Is peanut butter stickier than syrup or jelly? Strong, stretchy, sticky, or sweet—everything around us has special properties which make them unique. See if you can identify and compare the characteristics of materials.
Chemical & Physical Change   
(Activity, Instructional Material (4), Test, Assessment Material (5))
Everything you see and touch has the ability to change. Sometimes substances change to form new substances. This is called a chemical change. Other times substances change but keep the same identity. This is called a physical change. Try these activities to learn more about chemical and physical change.
