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

Bitesize, animated videos covering many chemical reactions topics, organised into these chapters: rates of reactions, equilibrium, redox, electrolysis and energetics through engaging, bitesize animated videos.

This is an activeinspire flipchart which could be used by teachers to explain the concept of chemical reactions or to assess students' prerequisites.

This brief instructor-facilitated activity asks students to observe a simple demonstration, record their observations, and apply their knowledge to other conditions. It was written by Johnathan Hugh Broome from University of Southern Mississippi.

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.
This course is a core subject in MIT’s undergraduate Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

Introduction to Solid State Chemistry is a first-year single-semester college course on the principles of chemistry. This unique and popular course satisfies MIT’s general chemistry degree requirement, with an emphasis on solid-state materials and their application to engineering systems.
Course Format
This course has been designed for independent study. It provides everything you will need to understand the concepts covered in the course. The materials include:

A complete set of Lecture Videos by Prof. Sadoway.
Detailed Course Notes for most video sessions, plus readings in several suggested textbooks.
Homework problems with solution keys, to further develop your understanding.
For Further Study collections of links to supplemental online content.
Self-Assessment pages containing quiz and exam problems to assess your mastery, and Help Session Videos in which teaching assistants take you step-by-step through exam problem solutions.

About OCW Scholar
OCW Scholar courses are designed specifically for OCW’s single largest audience: independent learners. These courses are substantially more complete than typical OCW courses, and include new custom-created content as well as materials repurposed from previously published courses.

In this 8th grade science lesson, students prepare Soft Pretzels. While the pretzels bake in the oven, students activate yeast and observe the production of carbon dioxide, which causes the Soft Pretzels to rise.

In this 8th grade science lesson, students prepare Whole Wheat Soda Bread with fresh churned butter and Chai. While the bread bakes in the oven, students experiment with chemical leaveners and observe the chemical reaction that causes the Whole Wheat Soda Bread to rise.
