Girl Scouts

Who can attend

Bechtel Engineering Day is for Girl Scouts who have an interest in science and engineering. Although Bechtel doesn't charge a fee for attending these classes, many hours are invested by our volunteer team to make this event happen. Although we understand that emergencies arise, we ask that each scout who registers remain committed to this event.

NOTE: There must be one responsible adult (Troop leader or parent) who remains on Bechtel premises in the event of an emergency for each troop registered. This person should have the authority for your troop's scouts in case of any emergency, medical or otherwise. Please plan accordingly when registering your troop and make arrangements for a responsible adult to remain for duration of your troop's classes.

Suggestions for scout leaders

The Bechtel Engineering Day program is a wonderful opportunity for Girl Scouts to learn about different subjects and professions, and to possibly become interested in a subject that may develop into a career. Each course is tailored around a specific Science, Technology, Engineering, and Mathematics (STEM) subject. It is recommended (but not mandatory) that a Troop leader or parent (who has may have expertise in the given area), work with the Scouts to give them added preparation for the relevant courses. It's just an added advantage for the scout to learn more about the subject.  

Thank you for your interest. We are trying to make this program a successful one, and look forward to you helping us and the scouts accomplish this. We enjoy doing this each year, and look forward to seeing you in February. 

Happy scouting! 

How to register

You must have your Troop leader or parent submit your registration through the Girl Scouts of San Jacinto Council electronic registration system. Registration for this event is open.

The electronic registration system is available. (Note: Registration requests can no longer be accepted at any Bechtel e-mail address.)

Once classes are full, any remaining registration requests will be placed on a waiting list for that class. If you have to drop out of a class for any reason, the next scout on the waiting list will be contacted to see if she is still interested in attending. We will continue with this process until the empty spot has been filled.

After you register

Once the initial registration is complete, you will receive an automatic email confirming the classes for which you have been registered or those for which you have been placed on a waiting list.

Important Notes: Cadettes, Seniors and Ambassadors may register for up to three classes (descriptions listed below). See registration system for more information on class times.

Chemistry is the branch of science that explores the manner in which substances behave, react with one another, and respond to changes in their surroundings. Chemists explore how atoms are bonded together to form chemicals, how chemical systems work, and develop entirely new chemicals and chemical reactions.

Prior to Engineering Day, scouts are encouraged to do the following:
  • Research the four classical fields of chemistry (physical chemistry, inorganic chemistry, organic chemistry, analytical chemistry).
  • Discuss with your Troop leader or parent what you found out about each, including the differences and similarities of each field.
In the Chemistry course, the scout will:
  • Observe proper chemistry lab safety protocol
  • Review Material Safety Datasheets (MSDS) for two common household products, discuss the similarities and differences between each substance
  • Perform an experiment involving Iron and Copper Sulfate. The Scout must make a prediction about what will happen, perform the experiment, and record their observations, noting the difference between what they predicted and what actually happened.
  • Learn how gases behave under conditions. Scouts will construct a ‘Cartesian diver’ and watch what happens when they apply a pressure to the system.
  • Perform an experiment by mixing oil and water. Scouts will learn why oil and water behave the way they do when mixed
  • Shown several interesting demonstration experiments to illustrate the exciting possibilities of Chemical Reactions.
  • Talk to practicing Chemical Engineers, discuss careers in Chemistry and Chemical Engineering, and have an opportunity to ask questions about STEM related careers.

Digital Technology

Computing technology has come a long way since the first general-purpose computer, named ENIAC, was built in the 1940s (Did you know, ENIAC was operated by a team composed entirely of Women, hand selected because of their ability to perform complex calculations by hand?).  The Digital Technology course is designed to give scouts insight into modern computing and other applications of digital technology in general.

Please note, it is requested that scouts who sign up for this badge be proficient in keyboard use.

Prior to Engineering Day, scouts are encouraged to do the following:

  • Describe when it is OK and when it is NOT OK to share data. Discuss with your parent or troop leader what types of data can and cannot be shared. Write what you have learned in 100 words or more using a word processor.
  • Discuss with your Ttroop leader or parent proper disposal of digital technology. Write what you have learned in 100 words or more using a word processor.
  • Research three careers in the computers and/or digital technology field. Discuss each of them with your parent or troop leader. Write what you have learned in 100 words or more using a word processor.

Bring all of your responses with you to Engineering Day, we will discuss what you have learned in the course.

In the Digital Technology course, the scout will:

  • Review a brief history of digital technology over time
  • Make a prediction about the types of computers and other devices that will be available when the scout is an adult
  • Demonstrate the use of simple computer programs, such as spreadsheet programs, word processors, presentation software, etc. 


Drafting is a highly sophisticated method of drawing and/or representing engineering and architectural work. Drafting is used by engineers, architects and other craftspeople to communicate information on a day to day basis.
Prior to Engineering Day, scouts are encouraged to do the following:

  • Should sketch one room from their house (with approximate dimensions) and bring it with them to Engineering Day.
In the Drafting course scouts will:
  • Use CAD software to prepare and plot a sketch of a room in the scout’s house
  • Discuss with course leader why CAD software is important in the engineering industry. Scouts will prepare a description of 40 words or less and use CAD software to type out the description.
This course will use AutoDesk, AutoCad, and/or Bentley MicroStation software, due to the popularity of the software. This will give the scouts hands-on experience with leading industry drafting utilities.


Prior to Engineering Day, scouts are encouraged to do the following:

  • Discuss electricity safety with your parents, including what you can do to improve potentially unsafe conditions. With your family, perform an electricity home safety inspection, following these guidelines
  • Research, with your parents' help if required, electricity topics: what is the difference between direct and alternating current; how do batteries work; what are fuses and circuit breakers, how do they work, and why are they important; what does it mean to overload a circuit ? 

In the Electricity course scouts will:

  • Learn and demonstrate proper response to electrical emergencies
  • Make a simple electromagnet and use it to investigate magnetic attraction and repulsion forces
  • Learn to read an electric meter and learn how to determine the cost of electricity based on a meter reading
  • Discuss ways that you and your family can conserve energy
  • Construct simple electric circuits and learn how they work 


Engineering is science in action. Engineers employ scientific principles and cutting edge technology to deliver energy, make new products, and improve quality of life. Engineers design a variety of products, including cars, bridges, schools, power plants, and electronics. The engineering course will expose scouts to a variety of engineering concepts.

Prior to Engineering Day, scouts are encouraged to do the following:

  • Find an item in your home that has been manufactured (such as an appliance). With your parents, investigate how and why the item works. Research what sort of engineering was required to make this product.
In the Engineering course scouts will:
  • Review an engineering achievement that has had a major impact on society. Scouts will investigate about the engineers behind this engineering achievement and discuss any special obstacles that had to be overcome in the process.
  • Visit with practicing engineers. Scouts will learn about the work engineers do, the tools they use to complete their work, and see actual engineering reports.
  • Design an original piece of equipment for your scout troop. Scouts will employ systems engineering approach to decide how it will work and how it will work. Scouts will draw plans and explain to the course leader why the specific design was chosen.
  • Perform experiments to investigate the differences of wood, metal and plastic. Scouts will discuss with the course leader what they learn about each material.
  • Learn what it means to a registered Professional Engineer (PE) and discuss what types of work require an engineer to be licensed
  • Study the Engineer’s Code of Ethics and explain how it is similar to the Girl Scout Promise and Law

Nuclear Science

Nuclear science is the study of atoms, sub-atomic particles, and radiation.
Prior to Engineering Day, scouts are encouraged to do the following:

  • Research radiation. Discuss with your Troop leader or parent about the hazards of radiation to humans and the environment/wildlife. Show the radiation symbol, and explain where and when it should be displayed.
  • Look up the meaning of the following nuclear science terms: atom, alpha particle, beta particle, gamma ray, x-ray, nucleus, proton, neutron, electron, quark, isotope, ionization, radioactivity and radioisotope. 

In the Nuclear Science course scouts will:

  • Construct a cloud chamber. Scouts will work together to build the chamber and use it to observe how radiation interacts with the apparatus.
  • Learn about radioisotopes, including how and why they are used in industry
  • Learn about radiation meters and learn how different materials affect radiation levels, and the effect of proximity on radiation count
  • Learn about nuclear reactors. Scouts will discover how nuclear reactors work to turn nuclear energy into electricity
  • Learn about career opportunities in nuclear science  

Class Information: Juniors

The course for Juniors is based around engineering principles. During the Bechtel Engineering Day, Juniors will:

  • Learn about careers in Engineering. Scouts will visit with practicing engineers and learn what being an engineer is all about. Scouts are encouraged to write three things they have learned about being an engineer during their session and share what they have learned with their troop.
  • Examine actual engineering blueprints. Based on these models, scouts will design their own project using techniques similar to the professional blueprints. Scouts will use their design concepts (blueprints) to complete their simple project.
  • Learn about different fields of engineering, and investigate how they have helped form our past, present and future
  • Using the principles they have learned, scouts will complete two simple engineering projects, and demonstrate what they have learned to their troop members.
