In this lab exercise, students practice correctly using measurement tools, recording data, calculating density, using significant figures, and exploring the concepts of accuracy and precision.

This is a series of activities demonstrating that air has mass, takes up space, and can exert a force on objects enough to lift them.

This is an inquiry activity that relies of pervious understanding of balancing and weighing to introduce a properties of air.

This is a free textbook offered by Saylor Foundation. The Basics of General, Organic, and Biological Chemistry by David W. Ball, John W. Hill, and Rhonda J. Scott is a new textbook offering for the one-semester GOB Chemistry course. The authors designed this book from the ground up to meet the needs of a one-semester course. It is 20 chapters in length and approximately 350-400 pages; just the right breadth and depth for instructors to teach and students to grasp. In addition, The Basics of General, Organic, and Biological Chemistry is written not by one chemist, but THREE chemistry professors with specific, complimentary research and teaching areas. David W. Ball’s specialty is physical chemistry, John W. Hill’s is organic chemistry, and finally, Rhonda J. Scott’s background is in enzyme and peptide chemistry. These three authors have the expertise to identify and present only the most important material for students to learn in the GOB Chemistry course.

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.

Small groups of students examine a candle to consider its chemical properties. Class discussion follows to consider macro vs. molecular events, energy, phase changes, etc.

This investigation will have students testing how heating and cooling can change the state of matter. They will test a variety of materials determine whether a change takes place through heating/cooling.

ChemVantage is an Open Educational Resource for college-level General Chemistry. Instructors have free access to thousands of question items suitable for quizzes, homework assignments and exams. ChemVantage is most useful when used as an LTI Advantage app with the class learning management system (LMS). Student scores on assignments are automatically returned to the LMS grade book. In addition, instructors can use Gen Chem placement exams for advising, video lectures with embedded quizlets, reading assignments with key concept questions and clicker-less in-class polls to sharpen student engagement. Student licenses are only $2 USD per month or $16 USD/year. Institutions can purchase student licenses in bulk for as little as $2/student/year.

This activity provides students with the opportunity to gather data from a controlled experiment setting, interpret their findings and use the data to draw conclusions to solve a mystery.

Students will compare ingredients in two different pancake recipes, then taste the difference. We will talk about the chemical reaction that happened when the recipes are mixed and why there are bubbles in the pancakes.

This activity is a classroom lab where students observe and classify chemical and physical changes using the five characteristics of a chemical change, interpret their findings, and use evidence to support their findings.

Students develop and conduct an experiment using the law of conservation of mass to determine whether or not gum should be considered food. Students will compare the mass swallowed for sugar and sugar-free gum. This could be used to discuss solubility.

This activity is a guided inquiry where students will investigate if water molecules have any space between them.

A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.

This is a General Chemistry 1 course taught at Sowela Technical Community College. This course utilizes Openstax Chemistry resources with added videos, powerpoint slides, and assessments.

General Chemistry Syllabus

CH 221: General Chemistry

Course Overview: This chemistry course is designed for students majoring in science. The knowledge
from this course describes and explains atoms, molecules, properties of substances, and physical and
chemical changes. Topics covered include the Metric System, unit conversions, significant figures, basic
quantum mechanics and the structure of the atom, bonding theories and molecular geometry, and
calculations involving the mole.
Course Goals/Learning Objectives:
By the completion of this course, students should be able to:
1. Demonstrate familiarity with basic concepts in chemistry, such as atoms, molecules, matter,
phases, and energy.
2. Report laboratory data and calculation results with the correct number of significant figures and
units. Convert values from one set of units to another.
3. Interconvert between masses, molecular and formula mass, number of moles, and number of
particles. Perform calculations involving moles such as molarity.
4. Use the electron structures of atoms and their positions on the periodic table to explain and predict
properties of atoms, types of bonding, and periodic trends.
5. Write names and formulas of ionic and covalent compounds, and draw their Lewis structures.
6. Identify molecular geometry and predict polarity, hybridization, bond orders, and bond strengths
of molecules using bonding theories.

This book was designed for students enrolled in CHM1311 Principles of Chemistry at the University of Ottawa.
