Conservation of Mass Activities for 5th Grade Science

The resources below will provide students a comprehensive understanding of the conservation of mass. All of the following lessons are also included in the Kesler Science Membership.

5E Lessons

Lessons

The Conservation of Mass 5E Lesson includes materials for every "E" phase, including the Conservation of Mass Station Lab for Exploration and an interactive PowerPoint with digital INB templates for Explanation.

The lesson also includes introduction materials for Engagement, student-choice project ideas for Elaboration, and assessments for Evaluation.

After completing the Conservation of Mass 5E Lesson, students will be able to measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. [Clarification Statement: Examples of reactions or changes could include phase changes, dissolving, and mixing that forms new substances.] [Assessment Boundary: Assessment does not include distinguishing mass and weight.]

Essential Questions
  • In what ways can matter change?
  • During physical and chemical changes, does the mass of the substance(s) change?
Standards
  • 5-PS1-2 - Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
