4 volunteers from the museum held a STEM event at the Holy Trinity School. The event was for all 32 students in 3rd grade. Volunteers were Dave Brown, Chris Curtin, Pat Green, and Gary Johnson.

To accommodate the group size, the event was split into 2 sessions. Gary Johnson welcomed the group with a brief overview of Tektronix, the museum, and passed out sample electronic components for the students to view first hand.

The students were divided into four groups and rotated through four different exhibits. Gary Johnson demonstrated computer graphics with the 4052. Students were able to interact with our Instant Art program and view a computer program.

Chris Curtin demonstrated additive color. LED instrumentation, and iPhone construction. The additive color exhibit features a red, green, and blue flashlights shining onto a white screen. The LED exhibit features different LEDs and test equipment to measure the voltage drop of individual and tri-color LEDs and the use of PWM to vary the brightness. The iPhone exhibit is an exploded display of all the internal components.

Dave Brown demonstrated using an oscilloscope to view different sound waves, including demonstration operation of a speaker using a function generator and a microphone and guitar to examine sound waves. The students were able to view their voices, claps, and whistles.

Pat Green demonstrated the use of a USB microscope to examine the construction of different colors on a LCD and printed half-tone pages. The students also examined the details of fabric, their shirts, and hair.

It was a fun and rewarding day for both the students and volunteers.
