In this video segment adapted from ZOOM, the cast shows how the 34 steps in their Rube Goldberg invention use everything from gravity to carbon dioxide gas in order to accomplish one simple task: pouring a glass of milk.

In this video segment from ZOOM, Jillian explains how her simple machine uses marbles, levers, flowing sand, and a spinning wheel to water a plant.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

This is an lesson about spectrographs. Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint the inside of the containers black the day before construction. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

This is a hands-on activity to assess the students understanding of peptide and disulfide bonds formed during protein synthesis. Students demonstrate the process of dehydration synthesis by combining amino acids through peptide bonds creating molecules of water, and one protein amino acid strand. It can also be used to assess students understanding of the process of translation.

A zip line is a way to glide from one point to another while hanging from a cable. Design and create a zip line that is safe for a hard-boiled egg. After designing a safety egg harness, connect the harness to fishing line or wire connected between two chairs of different heights using a paper clip. Learn to improve your zip line based on data. Attach a motion sensor at the bottom of your zip line and display a graph to show how smooth a ride your egg had!

How do you build a tunnel 32 miles long -- under water? This video segment adapted from Building Big, follows the construction of the Channel Tunnel (nicknamed "Chunnel"), the engineering wonder that connects England to France.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut. Learners use a formula to calculate the calories in a peanut and then differentiate between food calories and physicist calories as well as calories and joules.

In this demonstration, the teacher will use a potato and hydrogen peroxide to generate oxygen in a closed environment. Students can then observe its effects on a burning wooden splint and on burning steel wool. They will understand that a large amount of energy can be released by the process of oxidation. As an extension, the teacher can discuss how the appearance of oxygen (produced by cyanobacteria) in Earth's early atmosphere initially resulted in the formation of large deposits of iron oxide (Banded Iron Formations) and then aided in the evolution of more complex life forms.

Introduces chemistry related topics pertaining to everyday life. Includes topics such as renewable energy, clean air and water and global climate change using a relatively nonmathematical approach. Includes atomic/molecular structure, the periodic table, chemical bonding, intermolecular forces, chemical reactions, acids/bases and the social and environmental role of chemistry. Recommended for non-science majors to fulfill the Gen Ed science with lab requirement.

This textbook is an adaptation of the Saylor Introduction to Chemistry book customized for CH 104 at Central Oregon Community College. Low-cost print available: http://www.lulu.com/shop/forrest-towne/introduction-to-chemistry/paperback/product-24034383.html

Upon completing this course students will:

Interpret the periodic table to describe elements of atomic structure for the elements and to make predictions about properties based on the position of elements on the table.
Apply atomic theory in describing atomic structure, making predictions about bonding and compound formation, and interpreting chemical reactions.
Construct and interpret Lewis structures as models for ionic and covalent compounds.
Describe ionic and covalent bonding and distinguish between the two, including descriptions of substances of each type at the observable scale.
Solve problems using dimensional analysis involving chemical substances and reactions, drawing on understanding of the mole concept, formula masses and reaction stoichiometry.
Read, write, and interpret balanced chemical equations, using proper equation syntax and standard symbolism to link such descriptions to phenomena that occur at the observable scale.
Interpret and carry out a set of written experimental instructions and then to convey the experimental results in a laboratory report.
Apply kinetic-molecular theory to describe solids, liquids, and gases.
Recognize acids and describe acidity according to the Bronsted-Lowry definition.
Use scientific (inductive) reasoning to draw appropriate conclusions from data sets or theoretical models. Characterize arguments as scientific, or not scientific.
Make measurements and operate with numbers properly to convey appropriate levels of certainty when drawing conclusions from experimental data. Identify patterns in data by graphical means.

Short Description:
CHEM 1114 - Introduction to Chemistry is designed for a one-semester introductory chemistry course. For many students, this course provides their first introduction to chemistry. As such, this textbook provides an important opportunity for students to learn some of the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The text has been developed to meet the scope and sequence of most introductory chemistry courses, including an initial emphasis on the skills required (chapter 1 and 2) for the laboratory portion of the course.
