Classroom Experiments
Nondestructive testing (NDT) education and programs are vital to building a strong workforce. By providing access to resources and experiences to students and teachers, we create a foundation for the future of the NDT workforce.
Hertz Activity
Grades 6-12
Explore how alternating current circuits work using neon lights and other materials, a key concept used in electromagnetic testing.
Walking Water
Grades K-8
Using water, food coloring, and straws explore capillary action, the process of liquid flowing in narrow spaces without assistance, a key concept used in liquid penetrant testing.
Simple Electric Motor
Grades 4-11
Construct electric motors using batteries, magnets, paper clips, and wire to investigate how motors and electromagnets work.
Slinky Experiment
Grades 4-11
Using just a slinky and your hands, model longitudinal and transverse waves, showing how particle behaviors are used to identify defects.
Tuning Fork Activity
Grades 3-11
With a tuning fork and water explore the connection between sound and vibrations, a key concept used in ultrasonic testing.
Doppler Effect
Grades 8-12
With a foam ball and a buzzer explore how sound waves are affected by other forces, a key concept used in ultrasonic testing.
