Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform.

Cola fountains: a nucleation spectacular


What happens when you drop Mentos candy into a bottle of cola? Surface area, candy glaze, carbon dioxide, and a small amount of time all make a difference. It is a short assessment geared to help students think about the phenomenon and learn what Myth Busters has uncovered in the investigation using three questions that check for understanding.
