Adjust the initial velocity of a third atom as it hits two bonded atoms and track the changes in energy during this interaction.

In this math activity, students conduct a strength test using modeling clay, creating their own stress vs. strain graphs, which they compare to typical steel and concrete graphs. They learn the difference between brittle and ductile materials and how understanding the strength of materials, especially steel and concrete, is important for engineers who design bridges and structures.

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

This unit focuses on underreported stories of migration and the local history of everyday people of the City of Newark. From the global stories of women migrants on the move to the wards of the City of Newark, we will examine the experiences of the people who live and inhabit these places and spaces, and who also make history.

Far too often we solely focus on major reported stories related to migration from the point of view of the elite, those in power, or the victors who wrote down their version of history for posterity. This unit seeks to reclaim history for those who resisted, suffered, lost yet triumphed. Anchored by Pulitzer Center migration resources, this unit explores the intersection of the history of the City of Newark (aka Brick City) and global migration using a variety of historical documents, texts, and visuals in which everyday people and the disenfranchised occupy an important space of representation.

Students explore how tension and compression forces act on three different bridge types. Using sponges, cardboard and string, they create models of beam, arch and suspension bridges and apply forces to understand how they disperse or transfer these loads.

Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

Through a five-lesson series that includes numerous hands-on activities, students are introduced to the importance and pervasiveness of bridges for connecting people to resources, places and other people, with references to many historical and current-day examples. In learning about bridge types arch, beam, truss and suspension students explore the effect of tensile and compressive forces. Students investigate the calculations that go into designing bridges; they learn about loads and cross-sectional areas by designing and testing the strength of model piers. Geology and soils are explored as they discover the importance of foundations, bearing pressure and settlement considerations in the creation of dependable bridges and structures. Students learn about brittle and ductile material properties. Students also learn about the many cost factors that comprise the economic considerations of bridge building. Bridges are unique challenges that take advantage of the creative nature of engineering.

This activity s a student project to construct and test the load bearing capacity of a scale model bridge from toothpicks.

During interactive read-aloud sessions, students identify how an author conveys mathematical information about animals' sizes and abilities. They then conduct research projects focusing on the same mathematical concepts.

Students are presented with a brief history of bridges as they learn about the three main bridge types: beam, arch and suspension. They are introduced to two natural forces tension and compression common to all bridges and structures. Throughout history, and today, bridges are important for connecting people to resources, places and other people. Students become more aware of the variety and value of bridges around us in our everyday lives.

Students act as engineers to learn about the strengths of various epoxy-amine mixtures and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two chemicals in exacting ratios to fabricate the strongest and/or most flexible thermoset possible.

A Brief Introduction to Engineering Computation with MATLAB is specifically designed for students with no programming experience. However, students are expected to be proficient in First Year Mathematics and Sciences and access to good reference books are highly recommended. Students are assumed to have a working knowledge of the Mac OS X or Microsoft Windows operating systems. The strategic goal of the course and book is to provide learners with an appreciation for the role computation plays in solving engineering problems. MATLAB specific skills that students are expected to be proficient at are: write scripts to solve engineering problems including interpolation, numerical integration and regression analysis, plot graphs to visualize, analyze and present numerical data, and publish reports.

This collection of activities is based on a weekly series of space science problems distributed to thousands of teachers during the 2009-2010 school year. They were intended for students looking for additional challenges in the math and physical science curriculum in grades 9 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be ‘one-pagers’ with a Teacher’s Guide and Answer Key as a second page. This compact form was deemed very popular by participating teachers.

This classroom lab is a guided practice for inquiry using brine shrimp as the subject to be investigated.

Imagine if vocabulary could come alive with the click of a button! Students create video posters to demonstrate knowledge of new economics vocabulary.

This chapter provides teachers with instructions to install a school weather station, and to build simple instruments to monitor weather conditions. Materials need to create a homemade weathervane include a two-liter soft drink bottle, a shallow metal pie pan, a plastic drinking straw, and a compass. Building an anemometer requires plastic cups, soda straws, a pencil with an unused new eraser on the end, a paper punch, and a thumbtack. Thermometers and a rain gauge must be purchased. A data table is included for estimating windspeed using the anemometer. The chapter includes research ideas that allow students to validate their instruments and test the predictive capability of resources such as the Farmer's Almanac. This resource is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

Students are introduced to the concept and steps of the engineering design process and taught how to apply it. Students first receive some background information about biomedical engineering (aka bioengineering). Then they learn about material selection and material properties by using a provided guide. In small groups, students learn of their design challenge (improve a cast for a broken arm), brainstorm solutions, are given materials and create prototypes. To finish, teams communicate their design solutions through class poster presentations.
