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 (link is external) 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 (link is external).

Chemistry

The goal of this lab is to introduce students to phase change diagrams. Students will conduct an investigation that will allow them to collect temperature readings of water from its solid state to its gas state.

In this lab students will conduct an experiment that will allow them observe how different phases of matter conduct energy differently. Specifically, students will be using marbles (clumped together with different densities) to represent the three phases of matter and see how a golf ball will transfer its energy differently through each phase.

This short one day lab experience gives students a closer look into how the bonding between atoms of a compound impacts how the compound looks and behaves. Specifically, students will identify how ionic compounds and covalent compounds differ in properties of shape, solubility, melting point and conductivity.

In this unit the students will be introduced to the progress of the atomic theory. There are lessons and online you tube video that describe the atomic theory progress. An activity on how to explain the fact that electrons do not have specific orbit is suggested as an in class demonstration. There is a time line tool that is suggested for an online collaborative assignment.

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.
