Original Prompt

can you help me create a science lab worksheet for my 5th graders? The lab is one where the students are comparing distances and brightness for 5-ESS1-1 using a flashlight. Include tables for evidence.

This lab activity focuses on understanding the relationship between distance and brightness. Students will explore how light behaves when a flashlight is moved closer or farther from a surface, specifically a wall or poster board. The experiment aims to demonstrate why the Sun appears brighter than other stars, despite many of them being larger or hotter. Key components include materials needed for the experiment, safety precautions, predictive questions, a structured procedure for conducting observations at various distances, and reflective analysis questions to synthesize findings from the experiment.
