This activity gives students a way to look at how organisms are connected to ecosystems through the cycling of matter and the flow of energy. By the end of the activity, students will be able to make distinctions between how matter and energy are used and transferred and will be encouraged to apply this important crosscutting concept to the world around them.
First, students observe an animal, then they reflect on how it uses matter from food to build body structures and energy from food to do things. Students look at food as “packages” of matter and energy that animals (and plants) consume. They also think about wastes, such as poo, pee, sweat, heat, and carbon dioxide. This is a focused activity best used as part of an extended matter and energy-themed experience, and it works best after students have had time to explore, check out organisms in other ways, and be physically active.

Students will participate in a demonstration that will show the interconnectedness of a food web such that when one component is affected, the whole web is affected in some way. This is important for students to understand, as we are part of food webs and we need to be thoughtful about our decisions.

Almost all Anatomy and Physiology course require the student have a basic level of chemistry knowledge. Lesson 02 Chemistry covers the basics of inorganic chemistry, organic chemistry, physics, and nutrition that most A&P student need to make it through the course.
Keep in mind that each of these topics takes about a year of college to gain a better understanding; this video series is just a quick survey to get you up to speed.

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.

The modern human experience places a large emphasis upon the material world. From the day of our birth to the day we die, we are frequently preoccupied with the world around us. Whether struggling to feed ourselves, occupying ourselves with modern inventions, interacting with other people or animals, or simply meditating on the air we breathe, our attention is focused on different aspects of the material world. In fact only a handful of disciplines—certain subsets of religion, philosophy, and abstract math—can be considered completely unrelated to the material world. Everything else is somehow related to chemistry, the scientific discipline which studies the properties, composition, and transformation of matter.

This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.
