Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.

This course is an introduction to the calculus of functions of several variables. It begins with studying the basic objects of multidimensional geometry: vectors and vector operations, lines, planes, cylinders, quadric surfaces, and various coordinate systems. It continues with the elementary differential geometry of vector functions and space curves. After this, it extends the basic tools of differential calculus - limits, continuity, derivatives, linearization, and optimization - to multidimensional problems. The course will conclude with a study of integration in higher dimensions, culminating in a multidimensional version of the substitution rule.

Topics in this course include transcendental functions, techniques of integration, applications of the integral, improper integrals, l'Hospital's rule, sequences, and series.

Click! In the 1970s that word signaled the moment when a woman awakened to the powerful ideas of contemporary feminism. Today “click” usually refers to a computer keystroke that connects women (and men) to powerful ideas on the Internet. Click! aims to bridge the gap between those two clicks by offering an exhibit that highlights the achievements of women from the 1940s to the present. This exhibit explores the power and complexity of gender consciousness in modern American life.
Students will be able to explore, research, and analyze various topics such as women in politics, the Civil Rights Movement, the Feminist Movement, Body and Health, and Workplace and Family.
Educators will have the ability to retrieve lesson plans on various topics such as free lesson plans to give teachers content materials and activities that will allow them to integrate the history of the modern women’s movement into their curriculum and help students engage with important historical questions about the struggles that have made the United States more equal and democratic. Each lesson plan focuses on a historical topic that engages with the concerns of students: politics and social movements; body and health; and workplace and family. These topics are investigated through the histories of individual women, their organizations, and their struggles for greater rights and social justice. Their stories are situated within larger histories to help students connect the modern women’s movement to other changes in post-World War Two America.

With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students can find out what kinds of surfaces generate more or less friction. They also discover that both static and kinetic friction are involved when an object initially at rest is caused to slide across a surface.

In the first part of the activity, each student chews a piece of gum until it loses its sweetness, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount of sugar in the gum, and can be compared to the amount stated on the package label. In the second part of the activity, students work in groups to design and conduct new experiments based on questions of their own choosing. These questions arise naturally from observations during the first experiment, and from students' own experiences with and knowledge of the many varieties of chewing and bubble gums available.

Based on what they have already learned about friction, students formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter? and Does Area Matter?), students design and conduct simple experiments to test their hypotheses, using procedures similar to those used in the previous lesson (Discovering Friction). An analysis of their data will reveal the importance of weight to normal friction (the friction that occurs as a result of surface roughness) and the importance of surface area to the friction that occurs between smooth surfaces due to molecular attraction. Based on their data, students will also be able to calculate coefficients of friction for the materials tested, and compare these to published values for various materials.

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine the densities of solid objects, including the method of water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, and by considering the behavior of different solids when placed in water, students conclude that ordinarily, objects with densities greater than water will sink, while those with densities less than water will float. Density is an important material property for engineers to understand.

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

This lesson has been designed by the United States Environmental Protection Agency (EPA) as a teaching aid on the topic of weather. This lesson discusses the four seasons and weather patterns that correspond to seasons.

The following lesson is an introduction to the ideas and implications of animal tracking. Animal tracking is a useful method used within science and commercial industries. For instance, when planning the development coastal areas, animal presence and movement should be taken into consideration. The lesson engages students in an activity to monitor animal foraging behavior on a spatial scale. The students will break into groups and track each other's movements as they move through a pre-determined course. The results will be recorded both individually and collaboratively in an attempt to understand animal movement regarding foraging behavior. Students will also engage in a creative design activity, focusing on how they would design a tag for a marine animal of their choice. In conclusion, instructors will query the class on data interpretation and how spatial information is important in relation to commercial, conservation, and scientific research decisions.

Through two lessons and their associated activities, students do the work of scientists by designing their own experiments to answer questions they generate. Through a simple activity involving surface tension, students learn what a hypothesis is—and isn't—and why generating a hypothesis is an important aspect of the scientific method. In the second activity, with bubble gum to capture their interest, students learn to design and conduct controlled experiments to answer their own questions about the amounts of sugar (or artificial sweetener) in bubble or chewing gum.

In this lesson, designed for a heterogeneous group of students that includes English-language learners, students work together to plan a website based on their home knowledge. An introductory lesson outlines the structure and components of simple websites (home page, titles, headings, links). Students take home and complete a bilingual student and family interest survey, then work in groups of four or five to identify common themes among the responses. Each group makes a flow chart to think graphically about the contents of their planned website. Each student keeps a project notebook to record new ideas, summarize group work, and share the project with family members. The teacher can make the planned websites a reality using one of the online website-building platforms in the Resources list.

In a class discussion format, the teacher presents background information about basic human genetics. The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive alleles. Students determine whether or not they possess the dominant allele for the tongue-rolling gene as an example.

With the help of simple, teacher-led demonstration activities, students learn the basic physics of heat transfer by means of conduction, convection, and radiation. They also learn about examples of heating and cooling devices, from stove tops to car radiators, that they encounter everyday in their homes, schools, and modes of transportation. Since in our everyday lives there are many times that we want to prevent heat transfer, students also consider ways that conduction, convection, and radiation can be reduced or prevented from occurring.
