Just Plane Simple
This lesson introduces students to three of the six simple machines used by many engineers. These machines include the inclined plane, the wedge and the screw. In general, engineers use the inclined plane to lift heavy loads, the wedge to cut materials apart, and the screw to convert rotational motion into linear movement. Furthermore, the mechanical advantage describes how easily each machine can do work and is determined by its physical dimensions.
Energy Sources Research
Fact sheets are provided for several different energy resources as a starting point for students to conduct literature research on the way these systems work and their various pros and cons. Students complete a worksheet for homework or take more time in class for research and presentation of their findings to the class. This approach requires students to learn for themselves and to teach each other – rather than having a teacher lecture about the various sources and systems.
Clean It Up!
Students learn about a special branch of engineering called bioremediation, which is the use of living organisms to aid in the clean-up of pollutant spills. Students learn all about bioremediation and see examples of its importance. In the associated activity, students conduct an experiment and see bioremediation in action!
Copycat Engineers
This lesson introduces students to the idea of biomimicry — or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.
Light vs. Heat Bulbs
Students measure the light output and temperature (as a measure of heat output) for three types of light bulbs to identify why some light bulbs are more efficient (more light with less energy) than others.
Bridge Types: Tensile & Compressive Forces
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.
Cost Comparisons
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.
Marine animal tracking
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-determi
Turning the Air Upside Down
Students develop their understanding of air convection currents and temperature inversions by constructing and observing simple models.
How Tall Are We?
Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height
Waiting times between geyser eruptions
This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.
6 CASE tools
Enterprise systems are software applications that automate and integrate all many of the key business processes of an organisation. With some understanding of software development, you will learn about current development practices for this type of system and develop relevant skills to apply them to real-world problems. You will develop core skills in object-oriented analysis and design, allowing you to develop software that is fit for purpose, reusable and amenable to change.

U.S. says Gaddafi weakened but not defeated
U.S. military officials say Gaddafi is not close to a military breaking point even though coalition strikes have seriously degraded his fighting power. Deborah Lutterbeck reports.
