Investigating the Inverse Relationship Between Distance and Light Intensity Lab + Crossword Puzzle

Aligned with NGSS Standards: HS-PS4-1, Science and Engineering Practices

Explore the inverse relationship between distance and light intensity in this interactive physics lab! Using a lux meter app on smartphones, students will observe how light intensity decreases as the distance from a flashlight increases. This experiment provides a clear demonstration of inverse relationships in physics, reinforcing key concepts about wave behavior, light, and energy transfer. To deepen understanding, students will also complete a crossword puzzle that covers the four main mathematical relationships in physics, providing an engaging way to reinforce key terms and concepts.

What’s Included:

• Step-by-step procedure for the experiment

• Data recording sheet for easy student tracking

• Analysis questions focused on the inverse relationship

• Real-life scenarios to explore other inverse relationships (e.g., flashlight brightness, sound, temperature)

• Graphing activity for visualizing the data and inverse trend

• Crossword puzzle with key terms related to mathematical relationships in physics

• Includes answer key

Objective:

To observe and describe how light intensity decreases as distance from the light source increases, demonstrating an inverse relationship. Students will also learn key physics concepts through the crossword puzzle, enhancing their understanding of mathematical relationships.

Perfect for:

• High school physics classes

• NGSS-aligned investigations

• Exploring inverse relationships and other mathematical concepts in real-world contexts

• Hands-on learning activities and concept reinforcement with a crossword puzzle
