Part 1 Semion 1: Illustrate a design of your Rube Goldberg Device using objects you already have in your home since you will need to build it later. Your illustration/diagram should include the items listed in the checklist within the lesson. You may choose to draw it freehand and scan or photograph the drawing, or you may use a computer program to digitally create your device. Place your illustration/diagram below. Section 2: Answer the analysis and reflection questions below. 1. Describe your rationale for selecting the materials and structure of your device. How did your choices support the criteria and constraints of your design? 2. Select two energy conversions in your device and explain the forms of energy involved in those conversions, 3. Describe any energy transfers at the particle level that can be observed, 4. What type of system does your Rube Goldberg device represent? Describe the conversions in your device that support your answer. 5. Explain how your Rube Goldberg device design follows the law of conservation of energy. Part 2 Section 1: It's time to build your device to determine if your design needs revisions. You will need to turn in avideo clip or photograph of your device. Remember, with a photograph. you must include a written description of your device. Place your picture or link to your video below. Section 2: Make obseNations of your device's performance during three testing trials. Describe any unexpected results or gains or losses of energy to the surroundings. Trial Device Performance 1 2 3 Section 3: Answer the analysis and reflection questions below. 1. Evaluate the performance of your Rube Goldberg device against the given criteria and constraints. Describe the energy conversions that met the criteria and constraints and conversions that did not. 2. Refine your design to optimize efficiency. Describe the changes you made to your design and why you made those changes. 3. Test your refined design, Describe its performance. How did your changes increase or decrease the efficacy of your device? To begin, create designs for your Rube Goldberg device that meet the given criteria and constraints listed below: a design will show four energy transfers (this means five objects in your device). . design will minimize energy loss to the surroundings. Illustrate a design of your Rube Goldberg Device using objects you already have in your home since you will need to build it later. Your illustrationfdiagram should include the items listed in the checklist below. You may choose to draw it freehand and scan or photograph the drawing for your instructor, or you may use a computer program to digitally create your device. You will add your illustration to your Energy Models and Devices Worksheet. Public Domain Checklist Your diagram should include: ./ a written description of how each step works ./ labels for the energy transfers in your system by type (potential energy or kinetic energy) I labels for the energy conversions in your system by form (mechanical, electrical, radiant, sound, thermal, stored mechanical energy, chemical, gravitational, or electric potential energy) I label any possible energy losses to the surroundings through sound, heat, or radiation It's time to b our device and then determine if your design needs revisions. You will need to turn in a video clip or photograph of your device. If you submit a photograph, include a written description of the performance of your device during three testing trials. Your picture or video should include the items listed in the checklist below. Checklist Your picture or video should include: I the same energy transfers and objects in your illustrated design ./ labels (or verbal descriptions in video) for the energy conversions in your system by form (mechanical, electrical, radiant, sound, thermal, stored mechanical energy, chemical, gravitational, or electric potential energy) I labels (or verbal descriptions in video) for any possible energy losses to the surroundings through sound, heat, or radiation Public Domain
