I enjoyed the class. I love biology, so I enjoyed the medical references. It was more fun than my high school course!"
Thank you, Holly! This course has helped me tremendously, and I now feel more confident in my chemistry knowledge. I now feel more prepared for a college chemistry course, and I have you to thank!"
The instructor presented her lecture in a very easy to understand format. I liked how she tied the lecture into everyday life. It made it even more easy to understand, and the information sticks with me."
One of the truly outstanding aspects of this course is the inclusion of many examples of where and how chemistry affects our biologic lives."
I loved this course. It is a great review for college chemistry. Thank you, Ms. Holly Trimble!"
I've mentioned several times what a good writer you are. All the lessons were packed full of information, yet written clearly and interestingly. I know from experience what a challenging task that is....I have really enjoyed this course. I loved how you always included at least one chapter on how the topic of that lesson affects the human body. Also, the assignments were fun!"
I really enjoyed the course, and I hope to take another course with you again someday. You did a good job of giving me the edge I need for later on in my Chemistry studies. Thanks."
This is the first online course I have ever taken and I really learned a lot. I think it will help me get through the organic chemistry class that I am taking in the spring. Thank you for teaching me the basics about chemistry. The last time I took a chemistry class was in high school over 26 years ago, and this was a good refresher course."
Excellent course! Exactly the overview and type of content that I needed to better understand chemistry. The instructor was professional and helpful, and the exercises were at the right level for even the non-chemist to understand. Thank you!"
This course has certainly created a good foundation as I start my new career in healthcare. Holly has a way of explaining and simplifying topics to make it easy, especially for someone like myself who has no background in chemistry. Thank you, Holly!"

Learn about the three main states of matter (solids, liquids, and gases), where they are in your body, and how they change from one state to another. You'll also learn about the particles that make up matter, the differences between elements and compounds, and physical and chemical characteristics of substances. Then, learn everything you need to know about energy — the ability to perform some sort of activity or generate heat.
Explore measurements in chemistry. We'll focus on volume, length, mass, and density and compare the United States' system of measurement with the metric system of measurement. You'll learn why scientists and health care professionals primarily use the metric system and how to convert from one system to another. Then, learn about the structure of an atom. We'll also talk about the difference between atoms and ions, and you'll learn which subatomic particles can vary in number in the atoms of an element. We’ll end the lesson with a discussion of the use of radioactive isotopes in medicine.
Explore the organization of the Periodic Table of the Elements. We'll talk about the three major classes of elements—metals, metalloids, and non-metals, and you'll learn about their major characteristics. We'll also discuss some specific elements and some of the roles they play in the function of your body. Then, we'll cover four types of chemical bonds—true covalent, polar covalent, ionic, and hydrogen bonds. We'll also talk about different ways that scientists represent molecules, and you'll learn about molecular, structural, and electron-dot formulas.
Explore the language of chemical equations. You'll learn how to interpret the letters, symbols, and numbers we use to write chemical equations. We’ll take the mystery out of balancing chemical equations, and we'll go over a step-by-step method for balancing them yourself. Then, we'll talk about the different factors that cause chemicals to react with each other, and you'll learn how the temperature, physical nature, orientation, concentration, and pressure of the reactants affect the speed of chemical reactions. You'll also learn about a concept called activation energy—the minimum amount of energy needed for a chemical reaction to occur.
Explore the topic of stoichiometry—the quantitative relationship between reactants and products. You’ll also learn about the importance of oxygen in your body and how it limits the amount of energy you can generate from the food you eat. Then, we'll go over some basic information about solutions. You'll learn the difference between solutes and solvents, and you'll find out why chemists call water the universal solvent.
Review chemicals called acids, bases, and salts. You'll learn about their behavior in water and about their unique characteristics. You’ll also learn about several disorders that may occur when the levels of ions get out of balance. Finally, we'll go over four types of bioorganic molecules—carbohydrates, lipids, proteins, and nucleic acids.

There are no prerequisites to take this course.
The instructional materials required for this course are included in enrollment and will be available online.
A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits.
Once a course session starts, two lessons will be released each week for the six-week duration of your course. You will have access to all previously released lessons until the course ends.
The interactive discussion area for each lesson automatically closes two weeks after each lesson is released, so you’re encouraged to complete each lesson within two weeks of its release.
The final exam will be released on the same day as the last lesson. Once the final exam has been released, you will have two weeks plus 10 days (24 days total) to complete the final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.
