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.

By the end of this section, you will be able to:Define matter and elementsDescribe the interrelationship between protons, neutrons, and electronsCompare the ways in which electrons can be donated or shared between atomsExplain the ways in which naturally occurring elements combine to create molecules, cells, tissues, organ systems, and organisms

This course introduces the parallel evolution of life and the environment. Life processes are influenced by chemical and physical processes in the atmosphere, hydrosphere, cryosphere and the solid earth. In turn, life can influence chemical and physical processes on our planet. This course explores the concept of life as a geological agent and examines the interaction between biology and the earth system during the roughly 4 billion years since life first appeared.

Carbon dating is a real-life example of a first-order reaction. This video explains half-life in the context of radioactive decay. Created by Sal Khan.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Students will compare the basis of the derivatives for different plastics in order to determine their expected carbon-14 content. They will then compare ratios of carbon-14 to carbon-12 in plastic samples and categorize the sample according to its percent bio-based composition. Teacher Background Information: This lesson is more of a context design to be used with an existing nuclear chemistry lesson plan. The goal is for students to see the applicability of nuclear chemistry beyond carbon-dating by showing how carbon-dating can be used to determine the carbon sources of products.  Students will need a basic understanding of the carbon cycle, and nuclear equations. The lesson will need students to learn about half-lives halfway through the lesson and that is left open to teach as you wish. There is room for extension to mass spectrometry if you want to incorporate it here for AP Chemistry or as an honors extension. I would suggest using the Flinn POGIL on Mass Spectrometry.
