 Energy Citations Database (ECD) Document #4220934 - ACTIVITY CONCEPT IN RADIATION CHEMISTRY
Alteration of the molecular hydrogen yield was demonstrated by varying the scavenging solute concentration and the activity of the scavenging solute.
The linear dependence of the molecular yields on the cube root of the solute molarity applies very well for dilute solutions of strong electroytes, however, in more concentrated solutions considerable deviation is observed. /energycitations/product.biblio.jsp?osti_id=4220934

 AllRefer - optical activity (Chemistry, General) - Encyclopedia
Optical activity is measured by two methods: optical rotation, which observes a sample's effect on the velocities of right and left circularly polarized light beams; and circular dichroism, which observes a sample's absorption of right and left polarized light.
Since each type of enantiomer affects polarized light differently, optical activity can be used to identify which enantiomer is present in a sample and its purity.
Certain molecular groups, known as chromophores, possess high optical activity due to mobile electrons that interact with light and are responsible for the color of certain objects (e.g. /encyclopedia/O/opticala.html

The purpose of this activity is to bring students in contact with the sort of dilemma that arises from the downsides of an otherwise beneficial technology and to teach them how it can be difficult to find answers to some problems.
The activity is not meant to be a debate, but rather a cooperative search for viable solutions, with an ear to the viewpoints of many different voices.
The activity is designed to teach students to think critically and to develop the ability to use their own judgment to shape their own opinions when "right" and "wrong" answers are not apparent. /EducationalServices/webquest/tg/pvc.htm - Chemistry Web Site Directory

 LABS -- Laboratory Assessment Builds Success
Historically, chemistry educators have often justified these investments by two related arguments: that “doing chemistry” is an integral part of learning chemistry, and that the acquisition of chemical knowledge, skills and attitudes somehow emerges from asking questions related to the activity in the laboratory.
They did, however, spread chronologically across most of a year’s general chemistry teaching at the secondary school level and they did feature various patterns of laboratory activity including computer interfacing, microscale techniques, and a variety of hands-on, minds-on efforts to make important concepts of chemistry very understandable to high school students.
Psychomotor outcomes include all the manipulative, “hands-on, minds-on” skills chemistry students are called upon to cultivate and use, ranging from reading a buret meniscus to suitable precision, to decanting the supernatant liquid from a precipitate, to adjusting a gas burner to a specified temperature range, to graphing data. /Chemistry/LABS/LABS00.html
