Science Technology Competition (North America)

Toshiba has organized the ExploraVision Awards (EVA), a science and technology contest for U.S. and Canadian students from kindergarten through high school, in collaboration with the National Science Teachers Association (NSTA) since 1992.

EVA is a science technology contest with a dream, predicting future technologies that might be realized in 20 years based on existing science and technology. Entering its 22th year of existence this year, EVA has very long history of any activity conducted by a Japanese company to support science education in the U.S. More than 330,000 students have participated, and the number of applications for participation exceeds 101,000 to date.

Every year, we invite the eight teams that have made the most outstanding proposals to Washington, DC to be presented with awards. In addition to offering the students a forum in which to exhibit their prizewinning projects, the event also affords them an opportunity to visit their local congressmen and senators in order to present their reports. Toshiba employees also participate in a variety of ways, including managing events and leading teams.


Children form teams with their teachers, and commence entry procedures from September. For each theme, the teams study the existing science and technology, and using this as a base propose a technology that they would like to see realized in 20 years.
The proposals are then reviewed, and in March the best 24 teams are selected as Regional Winners. Following this, the proposals made by the Regional Winners are published on the EVA website, and in April four teams are selected to receive First Prize, and another four teams are awarded Second Prize. In June, the students in these eight teams, together with their teachers and families, are brought to Washington, DC for the awards event (EVA Weekend).

Awards Event

On the day before the awards ceremony, the teams visit the offices of their local congressmen and senators and present their prizewinning reports.

On the morning of the awards ceremony, each team is interviewed by its local television station, appearing live on the morning news.

They have the opportunity to explain their projects to VIPs and the media.

Politicians and celebrities from the U.S. and Canada send congratulatory letters and videos.

The prizewinning students are congratulated by VIPs at the awards party.

Declared June 6, the day of the awards ceremony, to be ExploraVision Science and Technology Day.
First-place winners in Grades K-3, elementary school children from Oklahoma, was invited to the White House Science Fair and proposed their project.

2014 Prizewinners

1st Place Winners

GRADES K1-3 (Kindergarten to 3rd year elementary school)

• Theme: Hot Car Safety System
• School:John Ross Elementary - Edmond, OK
The Hot Car Safety system warns when a car gets too hot for people or animals to be in the car by sounding an alarm. Weight sensors placed under the seats of the car ensure that the system turns on to protect all occupants.

GRADES K4-6 (4th to 6th year elementary school students)

• Theme: Plant Power - Super-hydrophobic Lotus Leaf
• School: Locust Valley Intermediate School - Locust Valley, NY
Our innovation will involve the nano-imprinting of the lotus leaf pattern on airplane exteriors so that ice and snow no longer build-up and affect airplane safety. The surface of the lotus leaf is “super-hydrophobic,” it repels water. Currently, the airplane industry has to address ice and snow build-up after it has formed on the exterior of an airplane. The de-icing and anti-icing processes use chemicals that run-off into the water and impact the natural habitat. Our vision is to make airplane flight safer with this preventative measure.

GRADES 7-9 (1st to 3rd year junior high school)

• Theme: iGlasses - The Eyeglasses of the Future?
• School: Marlboro Middle School - Marlboro, NJ
The eyeglasses of the future will provide improved vision, greater connectivity, and early detection of eye diseases. iGlasses will automatically adjust its lenses based on the object being viewed and the needs of the user’s eye to provide perfect vision, eliminating continuous changes in prescriptions, need for bifocals, and eye strain. iGlasses will also provide the user with real-time content directly to the lens and scan the eye for problems. The lens will be made from a material that adjusts its refractive index based on an electric current. The frame will have iris and pupil tracking to determine the object the user is viewing, infrared sensors to get distance from the object, micro-cameras to detect changes in the dimensions and health of the inside of the eye, a microprocessor, a display on the lens, and technology for communication.

GRADES 10-12 (1st to 3rd year high school)

• Theme:Quantum Dot Energy Harvesters for Powering Implantable Medical Devices
• School: West Salem High School - Salem, OR
Presently, electronic medical implants such as pacemakers, defibrillators, and neurostimulators rely on batteries that require constant surgical replacement. A convenient and permanent solution will harvest the thermal energy of the human body through a simple heat engine made from quantum dots. Quantum dots are nanocrystals that exhibit special properties, namely their ability to easily morph into efficient semiconductors, which will revolutionize thermoelectric generators and supercapacitors. Heat engines made with quantum dots have high efficiencies because of their chemical potential energy, yielding high energy densities and power outputs. Our Quantum BioEngine system will generate energy through temperature gradients of the body using a solid state chip implanted subcutaneously. The convergence of quantum dot technology with biomedical devices will create a world where human power sustains human life.

2nd Place Winners

GRADES K1-3 (1st year kindergarten to 3rd year elementary school)

• Theme: S.A.F.E.R. (Saving All Friends Escaping Rip currents)
• School: Waldron Mercy Academy - Merion Station, PA
S.A.F.E.R. is designed to save people that become stuck in a rip current while swimming at the beach. It is a wearable, inflatable belt that stores both pressure and velocity sensors, and GPS technology that will save a swimmer from the dangers of a rip current.

GRADES 4-6 (4th to 6th year elementary school)

• Theme: WateRenew: Wave Power for Clean Water
• School: Countryside Montessori Charter - Land O' Lakes, FL
Our idea, WateRenew, will have wave wings to harness energy, and a cutting-edge desalination plant to generate drinking water from the ocean. The vacillating hydroelectric forces of the underwater swells provide renewable energy. The wave wings will provide electricity, with no extra carbon dioxide being released. Then, a new reverse osmosis membrane made out of grapheme will trap salt while allowing water molecules to flow through.

GRADES 7-9 (1st to 3rd year junior high school)

• Theme: Kidney Microfilter Regulation Device
• School: Northview High School - Duluth, GA
The Kidney Microfilter Regulation Device (K.M.R.D.) is an artificial silicone kidney that will be surgically implanted into a patient’s body. It will have scanning nanofilters that will identify and regulate levels of phosphorous and other large particles in the blood that can be harmful in high concentrations as well as figure out what particles to let through the artificial kidney membrane. The K.M.R.D. will have most functions of a healthy kidney such as releasing hormones, balancing particles, and checking substance levels in the blood as well as medical reporting features.

GRADES 10-13 (1st to 3rd year high school)

• Theme: LTCHDTM using P-SOT
• School: W. L. Mackenzie C. I - Toronto, ON
We propose the use of fully photonic (using light alone) optical transistors to boost optical computing. These “optical transistors” would effectively achieve greater processing power. These optical transistors would use photonic-saturation to saturate a nanocrystal to the point where it stops absorbing light of a specific wavelength, consequently letting excess light pass through. Our optical transistor will be capable of running at multiple wavelengths, allowing each unit to perform the function of multiple transistors simultaneously.
