Character collides with object so text pops up

Hey. So I'm currently making my first game on unity and I was wondering if there was a way to make text popup when the player collides with a certain object. Example, when the player walks over a certain block text pops up telling you how to maybe sprint or crouch. I'm relatively new to Unity and scripting and I'm not asking you to make a script for me I was just wondering if there was some way to do it. Thanks for your time!
