Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. Students also learn that objects of greater mass require more force to result in the same distance traveled by a lighter object.

This text, The Cause and Consequence of Human Trafficking: Human Rights Violations, is intended to convey the importance of understanding how the violation of human rights is a cause and consequence of human trafficking.

Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external torque is applied to the system the center of mass will be conserved.

The sparks will fly as The Professor discusses element number 58. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large trains. There is then a demonstration in which a loop "jumps" because of a changing magnetic field. Finally, formal lecture reviews the cross product with respect to magnetic force and introduces magnetic flux, Faraday's law of Induction, Lenz's Law, Eddy currents, motional EMF and Induced EMF.

In this TED Talk video, Capt. Charles Moore discusses the problem of plastic debris in our seas. The resource, "Charles Moore TEDTalk Video" included in "Lesson 4 Plastic Indestructible Waste" is a part of "Unit 02 The Human Footprint" included in Energy & Sustainability ES - Course 2

Beginning in 2016, Chem 103/104 transitioned to a student-focused, active-learning philosophy. Students progress to mastery of the course learning objectives by engaging in frequent, structured activities. These activities may be performed individually (pre-class activities), in small groups (discussion, lab, and some whole-class activities), or with an entire lecture section with answers submitted via Top Hat student response system. A Module comprises a set of related content that generally approximates a traditional textbook chapter. Each module is broken into Quanta with distinctive pre-class (brief introduction to content followed by assessment quizzes) and whole-class (higher level content development, “ConcepTest” assessments of individual learning, and small group-oriented activities) activities. UW-Madison Chemistry 103/104 Resource Book supports these activities by providing learning objectives, in-depth descriptions of the content, many worked examples, practice problems, and a glossary for each quantum.

In this video Paul Andersen explains how chemical analysis is important in determining the composition, purity and empirical formula of a compound. An empirical formula determination problem is also included.

Mr. Andersen shows you how to determine if a bond is non-polar covalent, polar covalent, or ionic.

In this video Paul Andersen explains how chemical change differs from physical change. In the laboratory macroscopic observations are used to infer changes at the particulate level. Evidence for chemical change include gas production, change in temperature, change in odor, change in color, and formation of a precipitate.

In this video Paul Andersen explains the difference between chemical and physical processes. Chemical processes occur when bonds are broken and reformed. Physical processes occur when intermolecular forces are broken and reformed. A gray area exists between these processes which can be either chemical or physical.

This course uses an open textbook University of Michigan Chemical Engineering Process Dynamics and Controls. The articles in the open textbook (wikibook) are all written by teams of 3-4 senior chemical engineering students, and are peer-reviewed by other members of the class. Using this approach, the faculty and Graduate Student Instructors (GSIs) teaching the course act as managing editors, selecting broad threads for the text and suggesting references. In contrast to other courses, the students take an active role in their education by selecting which material in their assigned section is most useful and decide on the presentation approach. Furthermore, students create example problems that they present in poster sessions during class to help the other students master the material.

Chemistry is the scientific study of matter and its interaction with other matter and with energy. It is the branch of natural science that deals with the composition of substances and their properties and reactions.
