Electrical Engineering--A Helping Profession
The Arizona State University Electrical Engineering Department provides a hands-on laboratory session for teachers and counselors who are participating in the W.I.S.E.(Women In Science and Engineering) Investments program. The main focus is to interest more students, especially women, in engineering, by demonstrating how engineers help us to live better lives. In this webpage you will find the simple experiments which demonstrate principles used by electrical engineers in achieving this. There are also explanations included that show how the principles behind these experiments help us to protect the enviroment and live longer lives.
Some general resources promoting women in the field of electrical engineering can be found at:
Electrical Engineering Profession
- Electrical Engineering Profession PowerPoint 97 presentation (638k)
- Briefly describes the emphasis areas within electrical engineering at ASU including electromagnetics, electric power, solid-state electronics, communications, controls, and signal processing.
- What is Electrical Engineering? - a four page (pdf) document (476k)
- Briefly describes the electrical engineering profession. Careers within solid-state electronics, electromagnetics, controls, communications and signal processing, and power engineering are addressed.
General Resources for Teachers
Ideas and links for integrating electrical engineering topics in coursework
Digital Logic Resources
Digital Logic Laboratory Information
Detailed descriptions of the software simulation and hardware construction of both a digital lock, and a flashing railroad crossing signal.
- Digital Logic PowerPoint 97 presentations (a free copy of the PowerPoint Viewer may be obtained from Microsoft)
- Digital Logic Tutorial and Design (130k)
- Describes the basic logic gates and the Boolean logic associated with each. From there a simple digital lock is designed using AND gates and inverters (NOT gates). In addition, a simple flashing railroad crossing signal is designed using the AND and XOR logic gates.
- Digital Logic Hardware Laboratory (574k)
- The hardware used to construct the digital lock and the railroad signal are described, including the breadboard and trainer board. The insides of the AND, NOT and XOR chips are examined. The procedures and electrical connections of the circuits being built are given in detail.
- Digital Logic Workbook in Excel 97 (117k)
- Includes truth tables for AND, OR, and NOT gates; a 4-input, digital combination lock demonstration and user "lock picking"; a railroad crossing light simulation; and homework questions. Students using these spreadsheets can learn about digital (Boolean) logic via the simulations in this workbook.
- Digital Combination Lock Hardware Experiment Instructions and Parts List (html)
- Describes a laboratory experiment suitable for middle school and high school students. The students will gain knowledge of mathematics (Boolean logic) and physics (electricity and devices). A materials list and step-by-step procedure are given.

Simple laboratory experiments were developed on the following topics:
- Static Electricity fundamentals and experiments
- Salt and pepper - demonstrate the attractive force between opposite charges
- Repelling balloons - demonstrate the repelling force between two objects of the same charge
- Electromagnetism basics and experiments [included in the NSTA's SciLINKS]
- Galvanometer - demonstrates the relationship between electricity and magnetism by creating and detecting magnetic fields
- Electromagnet - demonstrates the relationship between electricity and magnetism by using electricity to magnetize metal
- Electric motor - demonstrates a practical application of electromagnetism through the construction of an electric motor, which also shows how electrical energy is converted into mechanical energy
The static electricity experiments are useful in understanding how electrostatic precipitators work, and likewise the electromagnetism section helps us to comprehend the medical diagnostic procedure of magnetic resonance imaging (MRI).
