Eureka! Cartoons Reach K-12 Students with Engineering Concepts

The idea to teach science and engineering ideas through cartoons is not new to K-12 teachers (Donald Duck in Mathmagic Land is probably the best example). The Eureka video series is another instance that may have gotten lost over time. Cartoons cater to different learning modalities than typical classroom instruction but some cartoons are better then others. Eureka captures viewers’ attention with its’ absent minded characters who demonstrate physics concepts (mechanics) along to a clear and concise narration of the key concepts.

What is especially cool about the Eureka series is that the concert concepts aren’t lost in the silly animation (but, nevertheless, the animation is very silly).


Going Global in Engineering Education: Considerations at the 2008 ASEE Conference

The 2008 Annual ASEE Annual Conference and Exposition brought engineering professors and graduate students from across the US together in Pittsburgh, Pennsylvania to discuss engineering education. Some issues at conference included, connecting engineering departments to K-12 students and teachers, developing stronger freshmen engineering classes, and getting engineering students to think globally.

Professors are finding that going global means that connecting engineering students to humanities and language classes is very important. Professors at the conference talked about strengthening language requirements and creating partnerships between humanities departments and engineering departments, in an effort to get more students to study abroad and think global.

The language of math and science is almost always English, so therefore many American engineering students get off easy, with less rigorous language requirements then in other disciplines. However, as a presenter at the conference pointed out, it is important that American students not be allowed to take “language” for granted. Having students learn a new language is not about what language they learn but that there is an effort to learn. It is really a challenge to teach students about the difficulties of learning a new language and making them aware of global language barriers.

Previously, most engineering students were not focused on the humanities or language classes, but now it seems new efforts may promise to produce even more qualified engineers. Helping the students think globally has led to the development of groups like the Engineers Without Boarders, who are passionate about the environment and others in a global society and work to use their engineering know- how to make changes.

With engineering departments making some sort of global experience a requirement and thinking about ties to language and humanities, this is a trend worth paying attention to.

Solar Thermal Water Heater For Less Than $5

DIY thermal solar in progress photo

The instructables web site provides how to guides on many topics. The origins of the site trace back to the MIT Media Lab. Solar Thermal Water Heater For Less Than $5

This project will create a DIY solar hot water heater for less than five dollars (if you have access to a garbage dump). It will allow you to see the principles of solar water heating in action, and is highly customizable.

Its a great way to learn about using the renewable energy of the sun to produce useful effects, in this case hot water. You can use these instructions to build a device that will actually heat enough water to use in the home, but it would require modifications.

Materials needed:

* Water
* 2 buckets
* Drill (with both drill bits and screw bits)
* Some scissors
* A saw (a simple hand saw will do)
* Some wood
* A pane of glass.
* The back of a small refrigerator.
* 12 feet of air pump hose used in fish tanks
* Backing material (we used an old door mat)
* A box of wood screws
* Aluminum Foil
* Role of duct tape
* Angle Cutter (or hack saw)

Time:

This project took about 3 hours of constructions time. It took a couple weeks to find all the parts.
