Engineering in Reverse!

5.0 stars

Students learn about the process of reverse engineering and how this technique is used to improve upon technology. Students analyze push-toys and draw diagrams of the predicted mechanisms inside the toys. Then, they disassemble the toys and draw the actual inner mechanisms. By understanding how the push-toys function, students make suggestions for improvement, such as cost effectiveness, improved functionality, ecological friendliness and any additional functionality they determine is an improvement.

Students' eyes are opened to the value of creative, expressive and succinct visual presentation of data, findings and concepts. Student pairs design, redesign and perform simple experiments to test the differences in thermal conductivity (heat flow) through different media (foil and thin steel). Then students create visual diagrams of their findings that can be understood by anyone with little background on the subject, applying their newly learned art vocabulary and concepts to clearly communicate their results. The principles of visual design include contrast, alignment, repetition and proximity; the elements of visual design include an awareness of the use of lines, color, texture, shape, size, value and space. If students already have data available from other experiments, have them jump right into the diagram creation and critique portions of the activity.

Students learn the value of writing and art in science and engineering. They acquire vocabulary that is appropriate for explaining visual art and learn about visual design principles (contrast, alignment, repetition and proximity) and elements (lines, color, texture, shape, size, value and space) that are helpful when making visual aids. A PowerPoint(TM) presentation heightens students' awareness of the connection between art and engineering in order to improve the presentation of results, findings, concepts, information and prototype designs. Students also learn about the science and engineering research funding process that relies on effective proposal presentations, as well as some thermal conductivity / heat flow basics including the real-world example of a heat sink which prepares them for the associated activity in which they focus on creating diagrams to communicate their own collected experimental data.

Interactive log p-h diagram for displaying refrigeration cycles of different refrigerants.
Automatic calculation of the COP for heat pumps and refrigerators. Free online tool, no registration required.

More detailed information:
The thermodynamic state of a fluid (e.g. the refrigerant R134a) can be represented in state diagrams as a single point. Complete processes such as refrigeration cycles are visualized by connecting points with lines. These connecting lines correspond to changes in the state of the fluid.

In refrigeration technology, the pressure-enthalpy diagram is by far the most frequently used state diagram. The pressure is mostly scaled logarithmically, hence the name log ph diagram.

The thermodynamic properties of a refrigerant are represented in the state diagram as lines of constant state variables - so-called isolines.
