What to expect from an Engineering Ambassador School Visit:

We will send two or more Engineering Ambassadors (EAs) to your school. We cover grades K-12 and tailor the presentation to the grade level. EAs can visit a class or do a larger format presentation with Q&A (and no hands-on activity) for larger audiences or assemblies. They generally present a 10-15 minute engaging TED style talk on an engineering topic (please see list of possible presentations – grade levels are merely guidelines, we may be able to tailor a presentation to your needs).

Presentations are usually followed by a related hands-on activity. Ideally, class sizes of 20-40 students work best for hands-on activities, although we have accommodated as many as 100 (with help from the school). We ask that you provide a computer that is connected to a projector, sound, and internet access. Powerpoint is preferred. We will do the rest.

Time allotment: generally a class period per presentation, but we are flexible. There is no charge for our visits.

In addition to presentations on engineering topics, we offer a presentation called "My College of Engineering Experience," which individual EAs prepare based upon their unique College of Engineering experience.  These presentations give students a glimpse of one engineering student's experience at  the University of Nebraska, College of Engineering.

Presentation Topics and Descriptions

Aquaponics

In this presentation, students will learn all about aquaponics (the combination of aquaculture and hydroponics) and the engineering behind it. They will discover how this method of growing crops is very beneficial! Finally, they will learn about aquaponics’ future as an agricultural method and how it could be implemented for the benefit of the planet. The activity includes exploring how a bell siphon works.
  • Level: Upper Elementary, Middle, or High School

Bridges

For this presentation, students will learn about the basic forces acting on bridges, including compression, tension, torsion, and shear. They will also learn about three main types of bridges: beam, truss, and suspension. The  types of engineers working with bridges and the future of bridges is also discussed.
  • Level: Upper elementary to middle school

Don’t Skip a Beat: Pacemakers engineered

Students learn about different types of heart beats as well as ways that pacemakers can stabilize the heart. They explore the physics behind pacemakers and discover the types of engineers that work with this technology.
  • Level: Middle or High School

Earthquakes and Structures

Students explore the various types of earthquake waves and learn about the physics behind earthquakes. They also discover how to design a building which can stand up to an earthquake using toothpicks and marshmallows.
  • Level: Late Elementary, Middle School or High School

Engineering the Human Body: Tissue Engineering

Students learn about the building blocks of life and how an understanding of biology can be used to engineer stem cells for use in the human body. They discover where stem cells come from and how engineered tissue can be used in medical applications.
  • Level: Middle or High School

Engineering to the Stars: Rocket Propulsion

During this presentation, students will discover the impact rockets have had on our lives today. They will also learn about how a rocket works: how all of its components function together to its advantage and allow it to rise up into the sky. Finally, students can see how engineers are planning to use rockets in future! Students will have the opportunity to design and fly their own straw rockets using our rocket launcher.
  • Level: Middle or High School

Fiber Optics

In this presentation, students will learn about the role of fiber optic cables in our world and the physics behind transfer of data in the form of light. They will then be inspired by the various types of engineers involved in the fiber optic technology!
  • Level: Elementary School or Middle School

The Future at Your Fingertips: Touch Screens

Students discover the science and engineering behind touchscreen technology and learn about the different types of touchscreens. They are challenged to think about how engineers contribute to the world of technology.
  • Level: Middle and High School

Get it Wright: An Intro to Flight

For this presentation, students will understand the four forces involved with flight and how engineers work to harness them, or limit them, in order to have planes fly! Students get the opportunity to engineer their own flying craft in the form of a paper airplane! We will talk about how the forces of flight act on their design and how to improve the force of thrust to improve their plane.
  • Level: Middle School and High School

Hydropower

Students discover hydropower as an alternative source of energy, learning how energy is harnessed from water and how it can be used. Students think creatively about how to design an efficient hydropower system.
  • Level: High School

The Magnus Effect

In this presentation, students will learn about a phenomenon in Physics call the Magnus effect. They will learn about how it works, every day uses of this effect, and engineering applications of it.
  • Level: Middle School or High School

An Ocean of Possibility: Electricity from Wave Energy

The presentation focuses on the use of wave energy as a renewable energy source and how engineers are working to make it a reality! Students will learn about wave energy’s dependability as an energy source, how it stacks up against other energy technologies, and finally, the current developments on its research.
  • Level: High School

Propellers at Work in Transportation

In this presentation, students will be taught about propellers and how they are unique. First, students learn about how propellers work to “propel” something. Then, they are educated on how engineers have harnessed this technology in boats and helicopters! Students will design and create their own paper propellers and see who can create the one that falls the slowest.
  • Level: Upper elementary or Middle School

Prosthetics

Students are exposed to prosthetic limbs, the science behind their movement, and the materials which compose them. Students also learn about applications of prosthetics and the engineering that goes into using them. Students will design and create their own prosthetic leg or hand.
  • Level: Middle School or High School
