Product Details

• Carolina Kits 3D®—Labs that use phenomena to support NGSS and 3-dimensional instruction.

This demonstration introduces students to the phenomenon of the metal activity series. Students apply prior knowledge of single-replacement reactions as they develop a model for ranking metals according to chemical activity. They use evidence from the demonstration to support the claim that a more reactive metal will replace the ions of a less reactive metal in solution. Students write balanced chemical equations for each single-replacement reaction that occurs in the demonstration.

Time Requirement
Total, 25 minutes. Teacher prep, 10 minutes. Demonstration and discussion, 15 minutes.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher’s manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives

• Observe and record the reactions of several metals with other metallic ions in solution.
• Write balanced single-replacement equations for each reaction observed.
• Develop a metal activity series by ranking metals from high to low on the basis of their reactions with other metals’ ions.

Prerequisite Knowledge and Skills
Students should be familiar with oxidation-reduction reactions and have the ability to write balanced net equations for single-replacement reactions.

NOTE: Instructions for this kit are based on the predict, observe, explain (POE) model. POE is primarily used in science classes. Specifically, POE has optimal effects when paired with demonstrations that allow students to make and record observations and then follow those observations with explanations.
