Seismology in the Classroom
Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an engineering firm that must analyze the seismograph for how it works and how to read the seismogram it creates.
How to be a Great Navigator!
In this lesson, students will learn how great navigators of the past stayed on course that is, the historical methods of navigation. The concepts of dead reckoning and celestial navigation are discussed.
To Absorb or Reflect: That is the Question
This is the last of five sound lessons, and it introduces acoustics as the science of studying and controlling sound. Students learn how different materials reflect and absorb sound.
Cellular Respiration and Bioremediation
In this lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, students are introduced to the process of bioremediation and several examples of how bioremediation is used during the cleanup of environmental contaminants.
Energy Systems and Solutions
The Energy Systems and Solutions Unit brings students through the exploration of science and engineering concepts as they relate to energy issues in everyday life. Issues surrounding energy production and energy consumption provide a relevant theme for learning basic science, math and engineering concepts, and also provide a convenient platform for introducing current scientific and technological developments into the curriculum. Energy-related issues touch on the lives of each and every student
Students learn about and use a right triangle to determine the width of a "pretend" river. Working in teams, they estimate of the width of the river, measure it and compare their results with classmates.
ࡁn introduction to our solar system: the planets, our Sun and our Moon. Students begin by learning the history and engineering of space travel. They make simple rockets to acquire a basic understanding Newton's third law of motion. They explore energy transfer concepts and use renewable solar energy for cooking. They see how engineers design tools, equipment and spacecraft to go where it is too far and too dangerous for humans. They explore the Earth's water cycle, and gravity as applied to or
Through nine lessons, students are introduced to a range of energy types electrical, light, sound and thermal as well as the renewable energy sources of wind, hydro (water) and solar power. Subjects range from understanding that the movement of energy at the electron level creates electricity that powers our world, to recognizing the Sun as our ultimate energy source. Through numerous hands-on activities, students explore a wide range of scientific topics related to the fundamentals of energy: k
Lasers, Let's Find 'Em!
Students research particular types of lasers and find examples of how they are used in technology today. Teams present their findings by means of PowerPoint presentations, videos or brochures. The class takes notes on the presentations using a provided handout. This activity prepares students for the "go public" phase of the legacy cycle in which they solve the grand challenge by designing and producing a laser-based security system.
Motor Exam: Anatomy: Spinal Cord Lesions
Spinal cord lesions often give UMN signs below the level of the lesion (from effect on the corticospinal tract) and LMN signs at the level of the lesion (from effect on the ventral horn or ventral nerve root). LMN signs are good for locating the level of a spinal cord lesion. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examinatio
Cranial Nerve Exam: Normal Exam: Cranial Nerve 7 - Sensory, Taste
Taste is the sensory modality tested for the sensory division of CN 7. The examiner can use a cotton tip applicator dipped in a solution that is sweet, salty, sour, or bitter. Apply to one side then the other side of the extended tongue and have the patient decide on the taste before they pull their tongue back in to tell you their answer. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure rela
Interactive Neuroscience v3.0
UCLA Interactive Neuroscience v3.0 contains multimedia resources to support first year neurosciences curricula.
NeuroLogic Exam: Introduction: Somatosensory Tracts
Now let's add the 2 ascending sensory systems that give us important clinical information for localizing lesions in the neuroaxis. The first system is the spinothalamic tract (pain and temperature) diagramed in light blue and the second is the Dorsal Column- Medial Lemniscus system (discriminatory touch and position sense) outlined in dark blue. Two important anatomical (and hence clinical) points about these two systems: - The spinothalamic tracts cross almost immediately upon entering the cord
Sensory Exam: Abnormal Examples: Light Touch
With light touch the patient indicates that the perception of the stimulus is different over the left side of the face. The feeling has an abnormal quality to it described as different, uncomfortable or burning. This would be called paresthesia or dysesthesia. Light touch causing pain would be allodynia. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous syste
This animation portrays the different linkages found in the chemical structure of the nucleotide. These links include phosphates, sugars, bases(1), bases(2), and basic sugar linkage.
Gait Exam: Abnormal Examples: Choreiform Gait Demonstration
This is a hyperkinetic gait seen with certain types of basal ganglia disorders. There is intrusion of irregular, jerky, involuntary movements in both the upper and lower extremities. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination permits "dissection" of the nervous system and localizes the disease when present. Instead of

How do estradiol, progesterone and testosterone regulate the hypothalamus in females? How does estradiol regulate the pituitary in the female? What other hormonal, neurogenic and psychogenic factors regulate the hypothalamic-pituitary unit in females? University of Cincinnati College of Medicine Reproductive Physiology Modules: Part 3.2.1.
6.2 A systematic approach to risk assessment
Headline news scares about stolen or missing data are becoming a frequent occurrence as organisations rely more and more heavily on computers to store sensitive corporate and customer information. This unit discusses the importance of protecting information and gives an overview of information security management systems.
