Students learn the fundamentals of using microbes to treat wastewater. They discover how wastewater is generated and its primary constituents. Microbial metabolism, enzymes and bioreactors are explored to fully understand the primary processes occurring within organisms.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Cellular respiration is the process by which our bodies convert glucose from food into energy in the form of ATP (adenosine triphosphate). Start by exploring the ATP molecule in 3D, then use molecular models to take a step-by-step tour of the chemical reactants and products in the complex biological processes of glycolysis, the Krebs cycle, the Electron Transport Chain, and ATP synthesis. Follow atoms as they rearrange and become parts of other molecules and witness the production of high-energy ATP molecules.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

In this seminar students will explore the hacking of glue! You will inquire about the way in which enzymes are a part of chemical reactions in the biological sense through simulations.  Experimental investigations will lead to the understanding of the denaturing process of enzymes.StandardsBIO.A.2.2.2 Describe how biological macromolecules form from monomers.BIO.A.2.2.3 Compare and contrast the structure and function of carbohydrates, lipids, proteins, and nucleic acids in organisms.

Chemical kinetics and buffers are two topics that are extremely difficult for students to understand. Combining the two topics will allow for a staggered, repetitive approach to teaching students to understand of how these two topics in chemistry actually work. Students will both qualitatively and quantitatively track the effect and enzyme has on a reaction, calculate the reaction rate and buffer capacity. Students will use a variety of lab techniques including calculations using Beer’s Law and spectrophotometry.

Let's Learn about Chirality is a video-based module that introduces the concept of chirality and stereoisomers to students. The module is an Open Educational Resources #OER containing short videos and fun quizzes* that you can take to test your understanding. In this module, you will learn to use different terms for stereoisomers and chiral molecules, recognize characteristics of stereoisomers, construct a model of 2-chlorobutane, identify the chiral carbons in chemical structures and assign absolute configurations to a molecule. The concluding video will briefly explain how chirality affects the chemistry of substances & pharmaceuticals. Click on View Resources and let's learn about Chirality.*For teachers, the Genial.ly quizzes are re-useable for your classes.*

Towards finding a solution to the unit's Grand Challenge Question about using nanoparticles to detect, treat and protect against skin cancer, students continue the research phase in order to answer the next research questions: What is the structure and function of skin? How does UV radiation affect the chemical reactions that go on within the skin? After seeing an ultraviolet-sensitive bead change color and learning how they work, students learn about skin anatomy and the effects of ultraviolet radiation on human skin, pollution's damaging effect on the ozone layer that can lead to increases in skin cancer, the UV index, types of skin cancer, ABCDEs of mole and lesion evaluation, and the sun protection factor (SPF) rating system for sunscreens. This prepares students to conduct the associated activity, in which they design quality-control experiments to test SPF substances.
