Students analyze video clips of kids rolling down a hill on skates, scooters, and bikes to determine whether mechanical energy is conserved.

A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Students use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.

Successful completion of this cooperative learning activity requires the active involvement of the individual, the small group and the entire classroom (collaboration). The goal is to make a simple task as complicated as possible by constructing a single complex machine.

TEXTBOOK ABSTRACT:

This book is intended for use in teaching undergraduate courses on continuous-time signals and systems in engineering (and related) disciplines. It has been used for several years for teaching purposes in the Department of Electrical and Computer Engineering at the University of Victoria and has been very well received by students. It has also been used to teach courses at numerous other universities, including Memorial University (NL, Canada) and Concordia University (QC, Canada).

This book provides a detailed introduction to continuous-time signals and systems, with a focus on both theory and applications. The mathematics underlying signals and systems is presented, including topics such as: properties of signals, properties of systems, convolution, Fourier series, the Fourier transform, frequency spectra, and the bilateral and unilateral Laplace transforms. Applications of the theory are also explored, including: filtering, equalization, amplitude modulation, sampling, feedback control systems, circuit analysis, and Laplace-domain techniques for solving differential equations. Other supplemental material is also included, such as: a detailed introduction to MATLAB, a review of complex analysis, and an exploration of time-domain techniques for solving differential equations. Throughout the book, many worked-through examples are provided. Problem sets are also provided for each major topic covered.

This website presents the principles of finite deformation continuum mechanics with many example applications to metals and incompressible viscoelastic materials (rubber). It can serve as lecture notes for a graduate level course in continuum mechanics for engineers interested in the subject.

Control Systems is an inter-disciplinary engineering text that analyzes the effects and interactions of mathematical systems. This book is for third and fourth year undergraduates in an engineering program.

In this video segment adapted from ZOOM, two solar cookers are tested against a control to see which can cook a "s'more" faster.

This article highlights the five essential components of cooperative learning, provides a quick overview of the research behind the strategy, describes three of the most common types, and offers ideas on how to get started using cooperative learning at the elementary level.

A brief refresher on the Cartesian plane includes how points are written in (x, y) format and oriented to the axes, and which directions are positive and negative. Then students learn about what it means for a relation to be a function and how to determine domain and range of a set of data points.

Indigenous People have been creating cosmetics and natural body remedies for thousands of years. Through trial and error, they have blended science and a deep understanding of human biology to connect with the world around them in very personal ways.

This video from NASA features the Cosmic Origin Spectrograph (COS), which allows scientists to use spectrographic analysis to assess the composition of intergalactic material.

In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions. CRaTER's purpose is to identify safe landing sites for future human missions to the moon; discover potential resources on the Moon; and characterize the radiation environment of the Moon. The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation."

Students learn about the many types of expenses associated with building a bridge. Working like engineers, they estimate the cost for materials for a bridge member of varying sizes. After making calculations, they graph their results to compare how costs change depending on the use of different materials (steel vs. concrete). They conclude by creating a proposal for a city bridge design based on their findings.

In this lesson, students find their location on a map using Latitude and Longitudinal coordinates. They determine where they should go to be rescued and how best to get there.

This article discusses how creating Readers Theater scripts from informational text can improve fluency and build comprehension.

This activity gives a visual representation of how we are able to observe many colors in a sunrise or sunset.

In this lesson, students create a compass and apply their reasoning about magnetism to how compasses work to help us navigate around the globe while utilizing the Earth’s magnetic field.

Short Description:
This book covers basic principles in the genetic improvement of crop plants. Emphasis is on methods of cultivar development in self-pollinating, cross-pollinating and asexually propagating crops. Relevant examples of crop improvement research in Africa are utilized to cover factors affecting cultivar release, multiplication, and distribution of high-quality seed.

The subject of this course is the historical process by which the meaning of “technology” has been constructed. Although the word itself is traceable to the ancient Greek root teckhne (meaning art), it did not enter the English language until the 17th century, and did not acquire its current meaning until after World War I. The aim of the course, then, is to explore various sectors of industrializing 19th and 20th century Western society and culture with a view to explaining and assessing the emergence of technology as a pivotal word (and concept) in contemporary (especially Anglo-American) thought and expression.
Note: In the interests of freshness and topicality we regard the STS.464 syllabus as sufficiently flexible to permit some — mostly minor — variations from year to year. One example of a different STS.464 syllabus can be found in STS.464 Technology and the Literary Imagination, Spring 2008.

Students gain experience with the software/system design process, closely related to the engineering design process, to solve a problem. First, they learn about the Mars Curiosity rover and its mission, including the difficulties that engineers must consider and overcome to operate a rover remotely. Students observe a simulation of a robot being controlled remotely. These experiences guide discussion on how the design process is applied in these scenarios. The lesson culminates in a hands-on experience with the design process as students simulate the remote control of a rover. In the associated activity, students gain further experience with the design process by creating an Android application using App Inventor to control one aspect of a remotely controlled vehicle. (Note: The lesson requires a LEGO® MINDSTORMS® Education NXT base set.)
