+# STARTER TEMPLATE FOR ACT-CMS LESSON PORTAL SUBMISSION
+# Replace all placeholder text with your actual lesson information
+# Remove any sections that don't apply to your lesson
+
+# BASIC METADATA (REQUIRED)
+# Use a clear, descriptive title that includes the main topic
+title: "Particle in a Box Energy Calculations"
+
+# Brief description for search results (1-2 sentences)
+description: "Students will calculate energy levels for particle in a box, examine how box length changes these levels, and predict absorption wavelength"
+
+# Longer description for the lesson page (use | for multi-line text)
+expanded_description: |
+  By completing this module students will examine the energies of a 1, 2, and 3-D box. 
+  Students will calculate both individual energy levels and differences in energy levels.
+  
+
+# COURSE INFORMATION (REQUIRED)
+# Choose ONE: "None", "Beginner", "Intermediate", "Advanced"
+programming_skill: "Beginner"
+# None: No programming experience. 
+# Beginner: Knows variables, conditionals, loops
+# Intermediate: Can write their own scripts from scratch
+# Advanced: Can write/develop software.
+
+# Examples: "Foundational Module", "Physical Chemistry", "Organic Chemistry", 
+# "Inorganic Chemistry", "Analytical Chemistry", "Biochemistry", "Materials Science", "Other"
+primary_course: "Physical Chemistry"
+
+# List other courses where this lesson could be used (optional)
+also_for:
+  - "Physical Chemistry Lab"

+# Estimated total time for all materials
+estimated_time: "1-2 hours"
+
+# Format of the module. Must be EXACTLY one of these two values (case- and
+# spelling-sensitive) so the home-page format filter groups lessons correctly:
+#   "Single Notebook"  or  "Multi-Part Module"
+format: "Single Notebook"
+
+# INSTRUCTOR INFORMATION (OPTIONAL)
+# Contact email for instructor access requests (optional - will use default if not specified)
+instructor_email: "cecilia.vollbrecht@kzoo.edu"
+# Note: Instructor materials will be located at: instructor-repo/{lesson-filename}/
+# where {lesson-filename} matches this YAML file's name

+# INSTRUCTOR DETAILS (OPTIONAL)
+# What level of students was this piloted with?
+student_level: "Undergraduate - Third Year"  # e.g., "Graduate", "Undergraduate - First Year", "Mixed Graduate/Undergraduate"
+# How many students has this been tested with?
+students_piloted: 7  # Number of students
+# Free-form notes for instructors
+instructor_notes: |
+  Additional context for instructors using this lesson:
+  This activity was piloted with students working on their own document but collaborating in pairs.
+  The set up allowed students to help each other and learn to troubleshoot better.
+  A lot of material was covered before the module, and the module was designed more to help students practice calculations
+  and see visualizations than to learn new concepts.
