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!

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.

The focus of this textbook is to introduce students to the foundations of General Chemistry and prepare students to be successful in the CH221-222-223 majors level chemistry series. The first part of the textbook focuses on the basic fundamentals of measurements in chemistry, the scientific method, an introduction into atoms, elements and trends of the periodic table. The second part of the textbook focuses on ionic and covalent compounds and their nomenclature, an introduction to chemistry reactions, stoichiometry, and solutions chemistry. Within each chapter, there is also a section entitled ‘Focus on the Environment’ that provides students an opportunity to learn and engage with environmental issues and concerns in the context of scientific studies and chemistry concepts. Within these sections are suggested written and discussion assignments that are appropriate for use in an introductory college-level course in chemistry.

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.

Course Goals and Learning Objectives. The goal of this course is to give the student a basic understanding of chemistry and physical processes in the context of food chemistry, metabolism and cooking. The course also necessarily makes connections to the future sustainability of food and water. We aim to prepare the student for the increasingly urgent and complex national dialogue on the interrelated topics of global climate change, energy, pollution, extinction and the food supply. The specific objectives of this course are to provide the student with the basic vocabulary of chemistry, and a basic understanding of the experimental process as it relates to food chemistry and cooking.
