Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the difference between its initial (unchewed) mass and its chewed mass can be used to calculate the percentage of sugar in the gum. This demonstration experiment is used to generate new questions about gums and their ingredients, and students can then design and execute new experiments based on their own questions.

Students investigate different forms of hybrid engines as well as briefly conclude a look at the different forms of potential energy, which concludes the Research and Revise step of the legacy cycle. Students are introduced to basic circuit schematics and apply their understanding of the difference between series and parallel circuits to current research on hybrid cars.

In this lesson, students will learn how great navigators of the past stayed on course that is, the historical methods of navigation. The concepts of dead reckoning and celestial navigation are discussed.

This activity was designed for blind learners, but all types of learners can use it to learn how the body self-regulates. This lesson plan teaches students how the human body self-regulates to maintain a stable internal environment despite changes in the external environment -- a process called homeostasis. Most of the activities detailed in this lesson plan can be done with visually impaired students if teachers adapt them using Resources for Teaching and Adapting Lessons for Students with Visual Impairments.

This course addresses essential learning outcomes in normal growth, development and nutrition across the lifespan, inclusive of aging. Its focus is on normal function rather than disease.

Students are introduced to the latest imaging methods used to visualize molecular structures and the method of electrophoresis that is used to identify and compare genetic code (DNA). Students should already have basic knowledge of genetics, DNA (DNA structure, nucleotide bases), proteins and enzymes. The lesson begins with a discussion to motivate the need for imaging techniques and DNA analysis, which prepares students to participate in the associated two-part activity: 1) students each choose an imaging method to research (from a provided list of molecular imaging methods), 2) they research basic information about electrophoresis.

Students will learn to solve compound inequalities, absolute value inequalities, and systems of equations, simplify radical expressions, solve quadratic equations and applications and simplify compound fractions, solve rational equations and applications, use function notation to solve problems and use exponential and logarithmic functions.Login: guest_oclPassword: ocl

After watching a 1940 film clip of the "Galloping Gertie" bridge collapse and a teacher demo with a simple pendulum, student groups discuss and then research the idea of motion that repeats itself specifically the concepts of periodic and harmonic motion. They become aware of where and how these types of motion occur and affect them in everyday applications, both natural (seasons, tides, waves) and engineered (swings, clocks, mechanical systems). They learn the basic properties of this type of motion (period, amplitude, frequency) and how the rearrangement of the simple pendulum equation can be used to solve for gravitational acceleration, pendulum length and gravity. At lesson end, students are ready to conduct the associated activity during which they conduct experiments that utilize swinging Android® devices as pendulums.

This course is designed for a face-to-face mode of instruction using online resources. Course content is divided into units. Each unit may include text readings, laboratory preparation, study questions, thought-provoking discussions, written assignments, learning activities, and group projects.Login: guest_oclPassword: ocl

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on air and land quality issues. Air quality topics include air pollution sources, results of poor air quality including global warming, acid rain and air pollution, as well as ways to reduce air pollution. Land quality topics include the differences between renewable and non-renewable resources, the results of non-renewable resource misuse and ways to reduce land pollution. (Water quality is introduced in a later lesson in a separate presentation, as it is the focal point of this unit curriculum.)

Students are introduced to the concepts of evolution by natural selection and digital evolution software. They learn about the field of evolutionary computation, which applies the principles of natural selection to solve engineering design problems. They learn the similarities and differences between natural selection and the engineering design process.

Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity. They learn what genetic engineering means and examples of its applications, as well as moral and ethical problems related to its implementation. Students fill out a flow chart to list the methods to modify genes to create GMOs and example applications of bacteria, plant and animal GMOs.

This class explores ways that writers portray human experience in their short stories, poems and plays. Through class discussions, lectures and creative responses, students will gain a deeper understanding and appreciation of literary works.‰Ű In this course, students develop and express their own analytic responses to a variety of works of literature, paying special attention to the ways that literary works are crafted and also to the ways that readers‰ŰŞ understanding of literature is subject to your personal perspectives and various theoretical frameworks.Login: guest_oclPassword: ocl

Planet Earth’s ocean covers over seventy percent of its surface, yet oceanographic research has only recently come to its full potential with the advent of new technologies. This course in Introductory Oceanography emphasizes the need to understand geologic, chemical, physical, and biologic processes or features that occur in ocean environments. It is designed to be thorough enough to prepare you for more advance work, while presenting the concepts to non-majors in a way that is meaningful and not overwhelming.Login: guest_oclPassword: ocl

This is an introductory course to Philosophy, which is the study of general and fundamental problems such as those connected with existence, knowledge, values, reason, mind, and language. Students will be introduced to the primary branches of Philosophy - ethics, logic, metaphysics, and epistemology. The course considers philosophers and works of Western Philosophy, including Plato, Hebrew scripture, Schopenhauer, Swedenborg, Buber, Kant, Hume, Locke and Berkeley.

Geology is a core science, along with physics, chemistry, and biology. It uses rigorous methods of inquiry that illuminate the history of the earth and its present-day geological activity. Geology allows us to discover how earth‰ŰŞs history and activity determine the state of the planet and its life forms. The study of geology also shows us how human behavior affects the earth. Topics we will cover include plate tectonics, earthquakes, volcanoes, rocks, minerals, geologic time, glaciers, rivers, geologic structures, layers of the earth, and reading maps. This course includes laboratory work and lab credit.Login: guest_oclPassword: ocl

The main goal of the course is to highlight the general assumptions and methods that underlie all statistical analysis. The purpose is to get a good understanding of the scope, and the limitations of these methods. We also want to learn as much as possible about the assumptions behind the most common methods, in order to evaluate if they apply with reasonable accuracy to a given situation. Our goal is not so much learning bread and butter techniques: these are pre-programmed in widely available and used software, so much so that a mechanical acquisition of these techniques could be quickly done "on the job". What is more challenging is the evaluation of what the results of a statistical procedure really mean, how reliable they are in given circumstances, and what their limitations are.Login: guest_oclPassword: ocl
