I don't have the newer EV3 Lego robotic kits, but while I'm looking at my NXT robot, I could describe what those "Try" functions do and maybe you could find an alternative?
The "Try Me" buttons on the brick are just meant to play a sound when the sensor is active. The Try Me options are Color, Touch, Light, Ultrasonic, Motor, and Sound which just plays a sound when the sensor is seeing color or light or being pressed, etc... I'll try to ask around for a EV3 kit and see if I can find similar, but this part is really just focused on the Inquiry part in using the built in "Try" method for students to discover how to plug the sensors into which ports and what they do.
Let me know if that helped or if you have any other questions.
