Chemical Reactions and Mass Inquiry Lab - MS 6-8 Science

Students will do two experiments that explore conservation of mass, characteristics of three types of chemical reactions, and how we know when each one has occurred. A link to energy transfer/transformation, thermal energy, and the conservation of energy can also be discussed with this activity if desired.

This product contains three complete labs that are differentiated for all of your students. All labs have comprehension questions, Claim-Evidence-Reasoning (C.E.R.) prompts, and a reflection section.

Essential Question:

• How does mass change in a chemical reaction?

What's Included?

• Teacher resource pages, including prep time, standards/objectives, teacher directions, materials, and additional resources
• Answer keys - suggested answer keys for the labs
• CER conclusion and reflection questions - Claim, Evidence, and Reasoning statements along with 3 reflection questions per lab

3 Differentiated Labs:

• Dependent Student Lab - A complete lab. This level is written with a combination of procedural instructions and inquiry questions. They are moderately student-centered with guided inquiry questions throughout the lab. Suggested for on-level learners.
• Modified Student Lab - A complete lab. This level provides the most structured lab experience. The lessons may eliminate parts of the lab and change the questioning to include sentence stems or multiple choice questions. Suggested for learners who may benefit from modifications.
• Independent Student Lab - A complete lab. This level is the most student-centered experience. Suggestions are made for the students to get started, but most of the decisions will be student-generated. The students will be responsible for most aspects of the lab and will have the least guidance. Suggested for advanced learners.
