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:Explain in what way smell and taste stimuli differ from other sensory stimuliIdentify the five primary tastes that can be distinguished by humansExplain in anatomical terms why a dog’s sense of smell is more acute than a human’s

Few people are aware of how crucial the sense of smell is to identifying foods, or the adaptive value of being able to identify a food as being familiar and therefore safe to eat. In this lesson and activity, students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. The teacher leads a discussion that allows students to explore why it might be adaptive for humans and other animals to be able to identify nutritious versus noxious foods. This is followed by a demonstration in which a volunteer tastes and identifies a familiar food, and then attempts to taste and identify a different familiar food while holding his or her nose and closing his or her eyes. Then, the class develops a hypothesis and a means to obtain quantitative results for an experiment to determine whether students can identify foods when the sense of smell has been eliminated.

Become a detective to solve the case of the smelly backpack! Act out the clues and draw conclusions to solve the mystery.

When Detective Bentley cannot figure out why his backpack is smelly, he retraces the events in his day to find clues. Taking on the role of detectives, the viewers act out the events of Bentley’s day and use textual clues to solve the case.

Learning Objective:
Draw conclusions from the facts presented in text and support those assertions with textual evidence.

Culture, Embodiment, and the Senses will provide an historical and cross-cultural analysis of the politics of sensory experience. The subject will address western philosophical debates about mind, brain, emotion, and the body and the historical value placed upon sight, reason, and rationality, versus smell, taste, and touch as acceptable modes of knowing and knowledge production. We will assess cultural traditions that challenge scientific interpretations of experience arising from western philosophical and physiological models. The class will examine how sensory experience lies beyond the realm of individual physiological or psychological responses and occurs within a culturally elaborated field of social relations. Finally, we will debate how discourse about the senses is a product of particular modes of knowledge production that are themselves contested fields of power relations.

Conviértete en un detective para resolver el Caso de la Mochila con Mal Olor! Actúa las pistas y saca conclusiones para resolver el misterio.

Cuando el detective Bentley no puede entender por qué su mochila huele mal, recorre los acontecimientos de su día para encontrar pistas. Asumiendo el papel de detectives, los espectadores representan los eventos del día de Bentley y usan pistas textuales para resolver el caso.

Objetivo de Aprendizaje:
Sacar conclusiones de los hechos presentados en el texto y respaldar esas afirmaciones con evidencia textual.

Do shark feeding frenzies really exist? Will sharks turn into a bunch of cannibals if they start competing for food? In this video, Jonathan wants to find out, and travels to Micronesia for an experiment. You won‰ŰŞt believe the fantastic result! Please see the accompanying study guide for educational objectives and discussion points.

An integrated course stressing the principles of biology. Life processes are examined primarily at the organismal and population levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.

Of all the animals in the oceans, the hammerhead shark may be one of the strangest looking. The exact purpose of the wide, flat head is a mystery, but several theories abound. In this video, we travel to the shark-infested waters of the Galapagos in Ecuador and to a research station in Hawaii to learn about the unusual habits of these sinister-looking sharks. Jonathan swims in schools of hundreds of hammerheads, and yet the sharks ignore him. What are the sharks up to? Please see the accompanying study guide for educational objectives and discussion points.

This lesson describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.

This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate, or are they acquired by experience? (And what does it even mean to call a concept ‘innate’?) Are ‘mental images’ pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course will include guest lectures by Professors.

Humans are omnivores (able to survive on many different foods). The omnivore’s dilemma is to identify foods that are healthy and avoid poisons. Taste and smell cooperate to solve this dilemma. Stimuli for both taste and smell are chemicals. Smell results from a biological system that essentially permits the brain to store rough sketches of the chemical structures of odor stimuli in the environment. Thus, people in very different parts of the world can learn to like odors (paired with calories) or dislike odors (paired with nausea) that they encounter in their worlds. Taste information is preselected (by the nature of the receptors) to be relevant to nutrition. No learning is required; we are born loving sweet and hating bitter. Taste inhibits a variety of other systems in the brain. Taste damage releases that inhibition, thus intensifying sensations like those evoked by fats in foods. Ear infections and tonsillectomies both can damage taste. Adults who have experienced these conditions experience intensified sensations from fats and enhanced palatability of high-fat foods. This may explain why individuals who have had ear infections or tonsillectomies tend to gain weight.

Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of the attempts, students hold their noses and close their eyes, while for others they only close their eyes. After they have conducted the experiment, they create bar graphs showing the number of correct and incorrect identifications for the two different experimental conditions tested.

This lesson explores the senses of smell, touch, taste, sight, and hearing. It provides an opportunity for students to meet a doctor who will show them how the senses are used when examining patients. The lesson introduces Dr. Virginia Apgar and the use of the Apgar Score in examining newborn babies.

Students will have to solve the real world problem of locker smell leakage by building an air filter that will cover the vents on the top of a locker. This project goes well with a curriculum on the particle nature of gases and phase changes.
