Area for teachers to provide descriptions of new materials, significant changes, new collaborators and other items of interest. Please consider posting stories and pictures here.
Free workshop for: 1) High school math and science teachers seeking to incorporate engineering problem solving into courses they teach and 2) High school teachers interested in offering ENED 1090 Engineering Models for college credit under the new College Credit Plus plan. The workshop will be June 22-26, 2015 on the UC campus. MathWorks has significantly reduced their pricing for schools to get MatLab so this is a great time to learn this tool. For more information or to register contact firstname.lastname@example.org.
Jason Shields and a couple of students from Kings High School appeared on Fox19 News recently describing the results of a project performed in the engineering class. The recycling tray stacker is going to save the Kings district about $15,000 per year in garbage removal fees and greatly reduce (by 88%) the volume of trash that they send to the landfill. The district business manager had been trying to come up with a solution to disposal costs for years without any success.

1. We shut the off power to the school heater around 8:30 am and the internal room temp was around 60 degrees. Outside temp 18 degrees.
2. At 10:15 the temperature of the solar heater was at 100 degrees and kicked on the internal thermostat. Outside temp 19 degrees.
3. One hour later, 11:15 the internal room temperature was up to 64 degrees and the solar heater was at 112 degrees. Outside temp 22 degrees.
4. At the end of the day 3:00 the internal room temp was at 71 degrees and the solar heater was outputting 120 degree air. Outside temp 32 degrees.
The kids were really excited to see their invention work so well and to heat my huge room!
Michelle Shafer introduced me to a new activity that is good for introducing the engineering design process. A description of the activity can be found on the PBS Kids site. The essence of the project is to use common materials to keep an ice cube from melting. This project can easily be adapted to a "challenge-based learning" format by creating a reason for the need for such a device. For instance, after the earthquake in Haiti there was a need to quickly get medicines to individuals and some of these medicines need to be kept cold. Taking the vantage point of a disaster relief agency that had to act quickly and use available materials students are asked to help meet this need.
The project can be easily expanded to include the need for surviving an air drop. There's opportunity to bring in science and math (heat transfer, velocity, momentum), social studies and communication (how do you mark a box that helps individuals know what is inside when they may not speak English), and even geography (what's the terrain like, are there animals that might also try to open the box).
Students at Harrison High School have created a biomass briquette press as well as a stove to burn the briquettes to quantitatively measuring which biomass produces the most heat. Biomass can be used as fuel in areas that lack other natural resources. Engineers Without Borders has created a number of press designs that can be used in third world countries (and in our own neighborhoods). The plans are included under the Chemical Engineering section.
What a deal! I found a free 2D CADD software program from Dessault Systemes (SolidWorks).

I am using this program now with my Engineering 1 class and it's working great. The program is very similar to AutoCad. The commands seem to be exactly the same. I was amazed.

King's High School students recently completed a mechanical engineering unit that included designing and building trebuchets. The designs were tested with 50lb weights (enough to storm the castle!). Most designs launched the object 50 - 70 yards. However, one design sent a 90 lb weight airborne for 97 yards!!
You can see a video produced by students on Youtube (these students are having way too much fun for this to be a high school class!)
