Objective: What is the relationship between temperature and the amount of light given off by the glow-stick?
1. How does a glow stick work?
2. What precautions should be taken during this lab?
3. Write a hypothesis for your experiment.
4. At what temperature should the control container be set ?
1. Activate the glow-stick according to the instructions given by your teacher.
2. Shake it back and forth to get it to glow.
Write a detailed plan for how you will set up an experiment to test your hypothesis. Include a control. Obtain teacher approval before you proceed.
Conduct your experiment.
1. Develop a qualitative method to express your results.
1. What does the data you collected tell you about the relationship between temperature and the amount of light produced in this reaction?
Conclusion and application:
These glow-sticks have been modified and have been advertised for use as fishing lures.
The ad explains how the stick will glow in water and attract fish. Many of the rivers commonly fished in Nevada are between 40 degrees in winter and 70 degrees in summer.
Will the glow stick be an effective lure for fish? Explain.
In your opinion and based upon your data, how warm does the water need to be to cause the glow-stick to give off enough light to attract fish?
Post Lab: Clean up your area. Dispose of all water and leave
