The course offers an introduction to quantitative analysis of geomorphic processes,and examines the interaction of climate, tectonics, and surface processes in the sculpting of Earth's surface.
Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a continuous stream. Through hands-on activities, students learn how the combination of adhesive forces and cohesive forces cause capillary motion. They study different effects of capillary motion and use capillary motion to measure surface tension. Students explore the phenomena of wetting and hydrophobic and hydrophilic surfaces and see how water's behavior changes when a surface is treated with different coatings. A lotus leaf is a natural example of a superhydrophobic surface, with its water-repellent, self-cleaning characteristics. Students examine the lotus effect on natural leaves and human-made superhydrophobic surfaces, and explore how the lotus leaf repels dewy water through vibration. See the Unit Overview section for details on each lesson in this unit.
Students are presented with the question: "Why does a liquid jet break up into droplets?" and introduced to its importance in inkjet printers. A discussion of cohesive forces and surface tension is included, as well as surface acting agents (surfactants) and their ability to weaken the surface tension of water. Students observe the effects of surface tension using common household materials. Finally, students return to the original question through a homework assignment that helps them relate surface tension and surface area to the creation of water droplets from a liquid jet.
Students extend their understanding of surface tension by exploring the real-world engineering problem of deciding what makes a "good" soap bubble. Student teams first measure this property, and then use this measurement to determine the best soap solution for making bubbles. They experiment with additives to their best soap and water "recipes" to increase the strength or longevity of the bubbles. In a math homework, students perform calculations that explain why soap bubbles form spheres.
In an activity that integrates science and art, students see, experience and harness the phenomenon of surface tension as they create beautiful works of art. Students conduct two experiments related to surface tension floating objects on the surface of water and creating original artwork using floating inks. They also learn historical and cultural information through an introduction to the ancient Japanese art form of suminagashi. They take the topic a step further by discussing how an understanding of surface tension can be applied to solve real-world engineering problems and create useful inventions.
Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two substances that typically do not mix, such as oil and water. This lesson and its associated activities are easily scalable for grades 3-12.
This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme of the Sound and Light unit a continuous story line throughout the lessons.
This unit focuses on teaching students about the many aspects of biomedical engineering (BME). Students come to see that BME is a broad field that relies on concepts from many engineering disciplines. They also begin to understand some of the special considerations that must be made when dealing with the human body. Activities and class discussions encourage students to think as engineers to come up with their own solutions to some of medical challenges that have been solved throughout the history of BME. Class time iincludes brainstorming and presenting ideas to the class for discussion. Specific activities include examination of the material properties and functions of surgical instruments and prosthetics, a simulation of the training experience of a surgical resident, and an investigation of the properties of fluid flow in vascular tissue.
Anthropologists attempt to answer the question of what it means to be human. In a sense, we all do anthropology because it is rooted in a universal human characteristic, curiosity. We are curious about ourselves and other people_ including the living and the dead. This course provides an introduction to the anthropological approach to the study of humans. It is a survey course that introduces anthropology as a four-field discipline, encompassing biological anthropology, archaeology, linguistics, and cultural anthropology. Aspiring to a holistic understanding of what it means to be human, anthropology is at the intersection of the humanities and the sciences, the most scientific of the humanities and the most humanistic of the sciences.The course begins with a basis in evolutionary theory and human variation. With this foundation, we will explore primate behavior and the fossil record to develop a better understanding of human evolution. We will discuss the archaeological record of early civilizations, the origins and use of language, and the concept of culture in the development of human societies, both extinct and extant. This class will also highlight the epistemological development of the field of anthropology and how religion, culture, and the scientific process pertains to the discipline of anthropology.
This course will introduce you to a general overview of the biological world. Important concepts will be reinforced and expanded upon through completion of weekly laboratory activities and homework assignments. Upon successful conclusion of the course, students will be able to do the following: Describe the nature of science, including its methods and its limitations; Describe the basic methodology of doing science and the scientific method; Use the scientific method to study everyday situations as well as in laboratory/field investigations; Identify, describe, and explain at a rudimentary level and present examples of, the characteristics common to all living things; Explain that living organisms are composed of molecules which interact in a variety of different chemical reactions necessary to sustain life; Explain that living organisms are comprised of one or more cells and are classified as prokaryotic or eukaryotic based on cellular characteristics; Describe the hereditary information possessed by living and explain how that information determines the cellular characteristics and functions (including basic Mendelian genetics); Explain and describe, with examples, the diversity of life, at different levels (basic molecular to ecological) and how it is hierarchically organized into systems; Explain how evolution by natural selection occurs, and describe the evidence that supports the theory of evolution; and more.
This is a survey course in which we will discuss the science behind historical and current environmental issues. We will discuss the major threats to biodiversity and ecosystem function.

Bacteria survive in almost all environments on Earth, including some considered extremely harsh. From the steaming hot springs of Yellowstone to the frozen tundra of the arctic to the barren deserts of Chile, microbes have been found thriving. Their tenacity to survive in such extreme and varied conditions allows them to play fundamental roles in global nutrient cycling. Microbes also cause a wide range of human diseases and can survive inhospitable conditions found in the human body. In this course, we will examine the molecular systems that bacteria use to adapt to changes in their environment. We will consider stresses commonly encountered, such as starvation, oxidative stress and heat shock, and also discuss how the adaptive responses affect the evolution of the bacteria. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.
Students engineer and evolve digital organisms with the challenge to produce organisms with the highest fitness values in a particular environment. They do this through use of the free Avida-ED digital evolution software application. The resulting organisms compete against each other in the same environment and students learn the benefits of applying the principles of natural selection to solve engineering design problems.
Students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches the continental shelf. Students make villages of model houses and buildings to test how different material types are impacted by the huge waves. They further discuss how engineers design buildings to survive tsunamis. Much of this activity setup is the same as for the Mini-Landscape activity in Lesson 4 of the Natural Disasters unit.
The purpose of this task is to address the concept of opportunity cost through a real world context involving money.
This task asks students to determine a recursive process from a context. Students who study computer programming will make regular use of recursive processes.

This book is suited for the Entrepreneurship or Innovation course with an emphasis on Sustainability or for a course devoted entirely to Sustainability.
What are the trends and forces underlying the changing character of the business-environment relationship? How they are creating significant entrepreneurial opportunities for individuals and companies? Around the world, the movement toward “sustainable development” has caused many firms to adopt policies and practices that reflect what is sometimes called a “sustainable business” or “triple bottom line” approach. “Triple bottom line” refers to the demonstration of strong performance across economic, social, and environmental indicators. Those measures serve as indicators of fiduciary responsibility to a growing set of concerned investors and therefore can help ensure access to capital. They also enable innovators to lower costs, create strategic differentiation, reduce risk, and position themselves for competitive advantage over rivals less attuned to trends.
The deep roots of sustainability thinking are now evident in widespread and increasingly visible activities worldwide, and Sustainability, Innovation, and Entrepreneurship explores this evolution; its necessity, its implications and its progression.
