Travelsound i50 ($70) is the name of this stylish portable speaker from Creative Japan. It’s designed for the 2G iPod Shuffle MP3 player an comes with a built-in battery which can be charged via USB.




To use the speaker, simply dock your player at the top. There’s also a cover included to protect your Shuffle when it sits on the i50. A carbiner makes it easy to clip the small speaker onto your belt or bag.
General Public Appropriate for anyone with an interest in chemistry or chemistry education.
Elementary / Middle School Science Appropriate for grades K-8.
High School / Introductory Chemistry Appropriate for grades 9-12, including first-year / introductory high school chemistry, but not second-year or advanced-placement (AP) high school chemistry (see First-Year Undergraduate / General).
First-Year Undergraduate / General Appropriate for college freshmen (topics typical of a collegiate, general chemistry course), including second-year or advanced-placement (AP) high school chemistry.
Second-Year Undergraduate Appropriate for post-general chemistry students (introductory courses in analytical, organic, or inorganic chemistry).
Upper-Division Undergraduate Appropriate for students who have completed the courses typically found in the first two years of the chemistry major curriculum (appropriate for intermediate or advanced courses in analytical, organic, or inorganic chemistry, or courses in physical chemistry or biochemistry).
Graduate Education / Research Appropriate for students who have completed an undergraduate degree in chemistry (including materials presented as part of a seminar and directed or independent study / research).
Continuing Education Continuing education refers to educational practice and materials aimed specifically at adults.
Domain describes a general area of study or interest within chemistry within which the cataloged resource falls; domain keywords represent the first level of specificity beyond the term chemistry itself; chemistry is understood to include chemical education.
Analytical Chemistry Analytical chemistry deals with separating, identifying, and measuring quantities of components of unknown mixtures and substances; methods include spectroscopy, chromatography, titrimetry, potentiometry, and gravimetry.
Biochemistry Biochemistry is the application of chemistry to the study of biological substances, structures, and processes at the cellular and molecular levels.
Chemical Education Research Chemical education research refers to the study of how students learn chemical concepts and the techniques instructors use to effectively facilitate this process.
Chemical Engineering Chemical engineering involves the design, construction, and operation of industrial plants capable of producing commercially important products from raw materials in large quantities.
Chemoinformatics Chemoinformatics encompasses the design, creation, organization, storage, management, retrieval, analysis, dissemination, visualization, and use of chemical information, particularly on and through the Internet.
Curriculum A curriculum consists of a description of the material covered in a course of study and the manner in which it is organized.
Demonstrations Demonstrations are activities that an instructor conducts before an audience to illustrate specific principles or concepts of chemistry. Demonstrations almost always involve props, and many are intended to highlight a particular type of physical or chemical change or property.
Environmental Chemistry Environmental chemistry is the use of chemistry to understand macroscale systems in air, soil, and water, and their interactions with one another and the living things that inhabit them.
History / Philosophy History refers to materials and activities that pertain to past events in the development of chemistry, as well as significant chemists and their contributions. Philosophy refers to principles, theories, beliefs, and practices in the realm of education, particularly with regard to instruction in the sciences.
Inorganic Chemistry Inorganic chemistry focuses on the properties of those non-carbon compounds generally excluded from organic chemistry. Of particular interest are the structure and bonding found within crystals, coordination complexes, and organometallics, as well as inorganic reactions and their mechanisms.
Interdisciplinary / Multidisciplinary Interdisciplinary / multidisciplinary activities seek to develop skills and knowledge in two or more content areas (some of which may be outside the field of chemistry).
Laboratory Instruction Laboratory instruction pertains to activities in which students conduct experimental procedures in laboratory settings. Such tasks involve the use of laboratory instruments and equipment and are usually designed to illustrate an important concept or principle of chemistry or to involved students in inquiry and discovery.
Organic Chemistry Organic chemistry focuses on the properties of carbon compounds. Of particular interest are the structure of organic compounds, how molecular structure determines physical and chemical properties, and the mechanisms through which and conditions under which one organic compound may be transformed into another.
Physical Chemistry Physical chemistry involves the application of principles and methods of mathematics and physics to explain and predict the behavior of matter by focusing on three key areas: quantum mechanics, thermodynamics, and kinetics / dynamics.
Polymer Chemistry Polymer chemistry focuses on the structure and properties of very long molecular chains consisting of many simple, repeating units. Of particular interest are the reactions and mechanisms involved in the formation of polymers.
Public Understanding / Outreach Public understanding pertains to activities intended to improve an appreciation for and understanding of chemistry among the general populace. Outreach consists of programs designed to develop the knowledge, interest, and skills of students and instructors at the elementary, middle, and high school levels.
Safety / Hazards Safety / hazards pertains to measures designed to ensure the safety of individuals in a laboratory or classroom setting, including information on potentially hazardous materials, equipment, or practices.
Element The name of any chemical element may be a keyword.
Pedagogy describes an aid to learning, an instructional approach, or a medium that is associated with the cataloged resource.
Analogies / Transfer Transfer refers to the ability to apply what has been learned in one context to a novel situation. Analogies, similes, metaphors, and other types of comparisons are common instructional techniques used to help students understand new concepts by linking them to familiar ideas.
Calculator-Based Learning Using calculators effectively is an important part of solving problems and analyzing data. Of particular importance are graphing calculators and calculator-based laboratory (CBL) equipment.
Collaborative / Cooperative Learning Collaborative / cooperative learning is a teaching strategy in which small, heterogeneous groups of students use a variety of learning activities to collectively improve their understanding of a subject. Individuals are responsible for their own learning as well as that of others in the group.
