Question Description

Directions: 1. Design an experiment to support the hypothesis that light travels in straight lines except at the point it enters a new medium. 2. Write experimental procedures using detailed, numbered steps. Do not use paragraphs. Do not use personal pronouns such as you or I. a. Incorrect: I will pour 10 mL of water into the graduated cylinder. I will transfer the water to a separate container. I will shine the light of the flashlight onto the surface of the water. b. Correct: 1. Pour 10 mL of water into the graduated cylinder. 2. Transfer the water to a separate container. 3. Shine the light of the flashlight onto the surface of the water. 3. To plan the experimental procedures, consider the following questions: a. What materials are needed? (If using the PhET simulation, list which tools and mediums will be used.) b. What safety procedures should be followed? (If using the PhET simulation, safety procedures are unnecessary.) c. What observations should be made? i. How will the angle of incidence and the angle of refraction be measured? d. What kind of data table is needed? (see example) 4. After writing the procedures and creating a data table, carry out the experiment. 5. Create a lab report with the following sections filled in. Submit a typed copy to the teacher via drop box: a. Experimental Question: How does a change in medium affect light? b. Hypothesis: c. Materials List: d. Safety Procedures (if necessary): e. Experimental Procedures: f. Data Table: g. Analysis and Conclusions: (Use the data to explain whether the data supports the hypothesis. Discuss any circumstances that may have affected the outcome. Answer the experimental question.)

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
