This is the student lab guide for the Claim, Evidence, Reasoning White Powder Lab. This guide is meant to be used in tandem with the educator slides in this bundle. Students will use this observational lab in order to learn to write CER's. 

This lesson is designed as a lab activity where students are trying to figure out what three unknown white powder substances are through making observations of known substances. This can be used in an high school level science class because it is not tied to a content standard; rather, it is tied to the Science and Engineering Practices (SEP's).

In this lab, students collect observational data and use that data as evidence in their CER's at the end. There are sentence starters in the CER section to help students gain access to writing the CER. This is a group assignment containing collaboration and communication.

ELD Scaffolds: Collaboration-Graphic Organizer, Sentence frames, cooperative learning.

UDL: Engagement: Fosters collaboration and community, Action and Expression: Maximizes transfer and generalization through use of graphic organizers and models. 

Science and Engineering Practices: This lesson focuses on 3 SEP's:

• Analyzing and Interpreting Data
• Engaging Arguments from Evidence
• Obtaining, Evaluating and Communicating Information
