Does my teacher hate me?

Last week we finished a major project in science and presented our works in the gymnasium, my teacher gave everyone a decent to near-perfect grade. But when he got to mine (a fake miniature pond) he yelled across the room "oh look, it's Herman's project, I'm sure it'll be WAY better than everything else!" and he was acting like what I made made no sense and didn't teach anything. He picked it up and started drinking the water, spat it out and was like "this sucks" and just dropped it on the floor spilling water everywhere. He gave me a 50% and wants me to meet him after school tomorrow. I have no idea what happened, but he had a clear problem with my project. He still stares at me in the hall, and says he's looking forward to talking with me all stern.
