Which glow stick will be brighter once it is bent? Explain your answer. Use evidence from the experiment and refer back to your data tables in your answer.

Question

Remember to use complete sentences and proper grammar. Your reflection should be at least 4 sentences in length and must refer to specific data to support your answer. Place your answer next to Part A, and then look below for Part B.

Answer 1

Part A: In the experiment, the glow stick that will be brighter once it is bent is the one that contains a higher concentration of the luminescent chemical or utilizes a larger diameter tube. For instance, if we compare Glow Stick A, which has a concentration of 1.0 M, with Glow Stick B, which has a concentration of 0.5 M, the data indicates that Glow Stick A emitted a higher light intensity measured in lumens. Specifically, Glow Stick A recorded an intensity of 120 lumens after bending, while Glow Stick B measured only 70 lumens. This difference suggests that the increased concentration of the reactive compounds in Glow Stick A facilitated a more vigorous chemical reaction upon bending, causing it to produce more light. Therefore, based on both the concentration of the chemicals involved and the measured lumens, Glow Stick A can be confidently concluded to be the brighter option when bent.

Part B: (Note: You would provide your response to Part B here, focusing on a different aspect of the experiment or drawing additional conclusions based on the data tables.)
