In this Earth Science activity, students will investigate rocks in an outdoor field trip. Students will be divided into groups and given a Ziploc bag to collect rocks. We will then return to the classroom, and the students will put their rocks into different groups. The different groups could be the size, shape, color, and texture of the rocks. We will then talk about the Rock Cycle and the three main types of rocks. Students will record their observations in their science journals.
This activity is a magnet science center. Young students learn about magnets through safe, hands on experiences.
This is an art project where oil paints and water is used. Students will have already explored the densities of oil and water.
This activity will give kindergartner the chance to see what happend when they paint an iodine solution over a lemon juice message. They get to make thier own invisible message!
This activity gives a visual representation of how we are able to observe many colors in a sunrise or sunset.
This course illustrates how knowledge and principles of biology, biochemistry, and engineering are integrated to create new products for societal benefit. It uses a case study format to examine recently developed products of pharmaceutical and biotechnology industries: how a product evolves from initial idea, through patents, testing, evaluation, production, and marketing. Emphasizes scientific and engineering principles; the responsibility scientists, engineers, and business executives have for the consequences of their technology; and instruction and practice in written and oral communication. The topic focus of this class will vary from year to year. This version looks at inflammation underlying many diseases, specifically its role in cancer, diabetes, and cardiovascular disease.
The central point of this course is to provide a physical basis that links the structure of materials with their properties, focusing primarily on metals. With this understanding in hand, the concepts of alloy design and microstructural engineering are also discussed, linking processing and thermodynamics to the structure and properties of metals.
Mechanics studies how forces affect bodies in motion--how, for example, a bullet is fired from a gun, or a top is set in motion by the flick of a wrist. This course will introduce the student to the core concepts of mechanics as applied to design, testing, and manufacture of safe and reliable products. Upon successful completion of this course, the student will be able to: Identify and use units, notations, and vectors used in mechanics; Identify and explain the concepts of forces, couples, and moments; Use the concept of forces and moments to compute resultants and equivalent systems in mechanics; Analyze mechanics of rigid bodies, such as trusses, frames, and machines; Identify and explain the concepts of friction and internal forces; Compute material properties of solid bodies, such as moments of inertia and mass moments of inertia; Compute strain and stress and understand the relationship of stress and strain for both elastic and plastic bodies; Compute stresses and strain in bodies subjected to tension and torsion; Compute stresses and strain in pressure vessels and composites; Identify and explain the concept of stress tensor and the constitutive relationship between strain and stress; Compute stresses and strain in simple and composite beams due to bending; Explain how stress is computed experimentally or using finite element formulations; Identify and explain material failure scenarios, such as fracture, fatigue, creep, and buckling.

This case is based on an actual article entitled "Baby Alert" that appeared in Consumer Reports (May 1999). The article raises some concerns about the safety of polycarbonate baby bottles, and recommends that parents dispose of them as a precaution. However, the American Plastics Council and the Food and Drug Administration have raised concerns about the experimental methodology used as well as the recommendations made in this article. The case has been used to help develop students' critical thinking skills in an introductory chemistry course for non-majors. It may be used to illustrate applications in polymer chemistry, quantitative chemical analysis, toxicology, endocrine disruption, and risk-benefit analysis.
This case, based on a lawsuit brought against the County of Los Angeles by homeowners suing over damage to their homes in the wake of the Portuguese Bend Landslide, teaches students principles of landslide movement while illustrating the difficulties involved with litigation resulting from natural hazards. Students first read a fictitious newspaper article (based on the actual events), then receive details about the geologic setting and landslide characteristics. With this information, the students are then asked to evaluate the possible causes of the disaster. The case was developed for use in a non-majors' introductory course in environmental geology.
This case study was inspired by a successful lawsuit brought by students against a professor at Pace University who had assigned them the task of calculating the cost of a single aluminum atom in a roll of aluminum foil. The case deals with the concepts of Avogadro's number and the mole, and so would be relevant to nearly all introductory level science courses including chemistry courses for non-science majors, general science courses, and, perhaps, some introductory level biology courses in addition to general chemistry.
A town meeting is the backdrop for a role-playing case about ground-level ozone air pollution. The case consists of a flier and scripts drawn from public comment records on the government mandate to reduce ground-level ozone by limiting nitrogen oxide emissions. Students play the parts of stakeholders and develop recommendations for reducing emissions.
The discovery of a mammoth frozen in the Siberian tundra is the backdrop for this case study, which explores theories for the extinction of the great Ice Age mammals and Homo neanderthalensis. Students research evidence for and against the different hypotheses and then discuss in class the merits of each. The case was designed for use in a freshman evolutionary biology course, where it was used as the last case in the term after studying the general principles of evolution, genetics, and biodiversity. Instructors of courses in anthropology and paleontology might also find it appropriate.
In this case study on sickle cell anemia, students are introduced to some of the key researchers responsible for determining the molecular basis of the disease and learn about the functioning of erythrocytes as well as the notion that changes in the environment can influence the functioning of cells. Students also become familiar with the process of osmosis and how it can influence the sickling of the erythrocytes. Throughout the case, students must address experimental design questions. The case was designed for use in the first semester of an introductory majors biology course.
In this dilemma case, Congresswoman Madeline Gibson must cast her vote on the fate of the lower Snake River dams. The stakeholders in this decision represent government agencies, small businesses, large industries, farmers, local tribes, environmentalists, and sports fishermen, and include among them many of her own family members. The case illustrates the conflicts that can arise when environmental concerns force people to reconsider long-standing policies with significant benefits and often entrenched supporters. Developed for an introductory-level environmental geology course, the case could also be used in environmental as well as biology courses.
