Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal force governed by the radius between the motor and accelerometer and the amount of mass at the end of the robot's arm. Students graph and analyze data collected from an accelerometer, and learn to design robots with proper weight distribution across the robot for their robotic arms. Upon using a data logging program, they view their own data collected during the activity. By activity end , students understand how a change in radius or mass can affect the data obtained from the accelerometer through the plots generated from the data logging program. More specifically, students learn about the accuracy and precision of the accelerometer measurements from numerous trials.

This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist. Students are told that two bodies have recently been recovered from two different lakes. Due to a mix-up at the morgue, the coroner's office is unable to determine which body came from which lake. The students' task is to develop a methodology to solve this mystery as well as determine whether the deaths were the result of murder or mishap. The case could also be used in instrumental analysis courses or adapted for a non-majors course in the general education curriculum.

Ever wondered what the heck an Acid or Base actually is? Were you ever super confused in high school or college chemistry? I've got a nice surprise for you guys in this video series. It's a little different than my usual videos, and I hope you all like the new direction I'm trying to take my videos. Enjoy and tell me what you think ;).

In this "clicker case," a three-year-old girl gets into the medicine cabinet and ingests an unknown number of aspirin tablets. Her brother calls 911 and the girl is taken to a nearby hospital, where she is treated. The case is used to discuss the Law of Mass Action, chemical equilibrium and equilibrium constants, pH, and weak acids and buffers in the context of medical management of a life-threatening emergency. It is called a "clicker" case because it is designed to be presented in a class that uses personal response systems, or "clickers." The case is presented via a series of PowerPoint slides (~400KB) punctuated by multiple-choice questions, which the students answer using their clickers. It could be adapted for use without these technologies. The case is suitable for use in an introductory biology course where integration with biologically relevant chemistry is an important course objective. It could also be used in a chemistry course.

CDC defining overweight or obese individual if weight is higher than what is expected as a healthy weight for a given height and body Mass Index (BMI). Further, overweight and obesity could be referred to the amount of excess body fat that causes health risks to an individual i.e. a weight-responsive comorbidity, however, a simpler clinical definition of obesity is limited to an excess of body fat or adiposity. BMI (kg/m2) is a widely used tool as it has a high correlation with adiposity, easy to measure, in addition, most clinical studies in relation to overweight and obesity depends on it.

Advanced Inorganic Chemistry is designed to give you the knowledge to explain everyday phenomena of inorganic complexes. The student will study the various aspects of their physical and chemical properties and learn how to determine the practical applications that these complexes can have in industrial, analytical, and medicinal chemistry.

Organic chemistry is the discipline that studies the properties and reactions of organic, carbon-based compounds. The student will begin by studying a unit on ylides, benzyne, and free radicals. Many free radicals affect life processes. For example, oxygen-derived radicals may be overproduced in cells, such as white blood cells that try to defend against infection in a living organism. Afterward the student will move into a comprehensive examination of stereochemistry, as well as the kinetics of substitution and elimination reactions. The course wraps up with a survey of various hetereocyclic structures, including their MO theory, aromaticity, and reactivity. Upon successful completion of this course, the student will be able to: Describe free radicals in terms of stability, kinetics, and bond dissociation energies; Describe the stereochemistry and orbitals involved in photochemical reactions; Describe enantiomers, diastereomers, pro-S and pro-R hydrogens, and Re/Si faces of carbonyls; Perform conformational analysis of alkanes and cyclohexanes; Describe reaction mechanisms in terms of variousparameters (i.e.,kinetics, Curtin-Hammet principle, Hammond postulate,etc.); Describe the chemistry of the heterocycles listed in Unit3 in terms of molecular orbital theory, aromaticity, and reactions.
