This STEAM lesson, "Invisible Sculptures," allows students to visualize magnetic and electric fields to meet NGSS Standard MS-PS2-5. Through a hands-on investigation, students create "sculptures" with iron filings and static electricity, providing visual evidence of unseen forces.

Following the investigation, students will critically evaluate their experimental design. They will analyze their methods, identify uncontrolled variables and potential sources of error, and suggest improvements. This project integrates art and scientific inquiry to build a deeper understanding of physical science.

Included Resources:

• 3-4 Day Lesson Plan: A detailed guide with a script, essential questions, vocabulary, and differentiation strategies.
• Student Handout 1: Field Investigation Log: A worksheet for students to record observations and sketches or photos of their magnetic and electric field "sculptures."
• Student Handout 2: Experimental Design Evaluation: A summative assessment where students analyze their investigation's weaknesses and propose modifications.
• Grading Rubric: A 4-point rubric to assess students' investigation, evidence, design evaluation, and artistry, aligned with NGSS standards.

Learning Objectives:

• Conduct an investigation to show the existence of fields between objects that are not touching.
• Analyze the patterns created by magnetic and electric fields.
• Evaluate an experimental design for variables, controls, and errors.
• Propose improvements to a scientific investigation.
• Create process-based art using scientific materials.
