I conducted an experiment for a physics lab and noticed that the warmer the elastic band was, the further it would stretch when I place the same mass on it. I’ve been told this is because of the glass-transition effect, thoughts?

They usually don’t. Warm rubber bands have more tension than cold rubber bands!
Do the experiment! Dangle something from one, then heat it up. It’ll contract. This is because elasticity comes from the randon jiggling of long chain elastomers. More heat means more jiggling and more pulling.
