I need help with this lab, along with the questions answered:
Procedures
- Before you begin, make a hypothesis about the appearance of light reflected from a mirror and then refracted by a clear container full of water. Your hypothesis should be a prediction of the differences between the reflected and refracted light based on what you have learned in this lesson and your own personal experiences.
- You will begin by practicing observing the beam of your flashlight for control purposes. (Note, it is also possible to compete this experiment with sunlight if you have access to a good sunny ray!).
- Next, use a mirror to reflect the light. Make 3 observations about what you were able to do with this reflected light. Be sure to record the observation in the proper section of your lab investigation report template. Try to reflect the light on a wall, to the floor, and toward another object.
- Are you able to observe the angle of reflection?
- Make notes about these observations in your notebook. These notes will be organized and documented in the results section of your lab report.
- Repeat step 4 with a piece of shiny metal rather than a mirror. Make note of any additional observations, including differences.
- Next, fill the large bucket or wading pool with enough water to submerge your foot. After placing your foot in the water, make general observations and record them in your lab report.
- What did your foot look like?
- Did it seem bigger or smaller?
- Did it look thinner or fatter?
- Did it have a shadow?
- Did the color appear to change?
- Then bend your foot in various ways and continue to make observations with these same questions.
- Fill a glass pitcher or jar with water.
- Shine a flashlight on one side of the jar and look at the light as it emerges.
- Record your observations about the angle at which the light emerges from the glass.
- Repeat the steps from #7 above with a plastic bottle (such as a 2 liter bottle).
- Complete the Analysis and Conclusion questions and summary.
Analysis and Conclusion Questions: Answer these questions in complete sentences.
1. What was your testable question?
2. What was your hypothesis? Make sure it is in an "if, then" format and you include your independent and dependent variable in the hypothesis for full credit
3. What was your independent variable?
4. What was your dependent variable?
5. What was your control in this experiment?
6. Did you need any safety precautions for this experiment?
7. Was your hypothesis supported by your data? Use at least three complete sentences and the data you obtained to explain your conclusion.
- What was your hypothesis about the difference between reflected and refracted light?
- Were you able to perform this experiment with just sunlight? Why do you think sunlight and the light from a flashlight both work for this experiment? Explain your answers using complete sentences and terms from the unit.
- What did you notice about the angle of reflection when you shined the flashlight beam on the mirror? Was there any difference when you used a piece of shiny metal? Can you explain this difference based on what you have learned about light in the lesson?
- Why did your foot look distorted in the bucket of water? Why does this relate to the information in this lesson?
- What were the differences in refraction between the plastic bottle and the glass jar? Why do you think this is so?
- Give a brief conclusion or summary about what you learned from this lab. The first sentence should explain your hypothesis. You should also have a sentence that describes the procedures you performed along with the results. Be sure to include information about reflection and refraction that you learned in this lesson as well as new information you observed during your investigation.
