Bell Work: 4/7/15 Describe any testing data acquired from yesterday or improvements that you made on your toy. Vocabulary Reference Use my portaportal or the articles at your table to find the meanings of the circled words. Participate in Accountable Talk with your team to compare the information you found on the word(s) above. Remember: ask meaningful questions & change or modify your work (if needed). Standards & EQs Standards Essential Questions O SPI 0807.T/E.1 Identify the tools and procedures needed to test the design features of a prototype. O SPI Recognize that electricity can be produced using a magnet and wire coil. O SPI Describe the basic principles of an electromagnet. O SPI Distinguish among the Earths magnetic field, a magnet, and the fields that surround a magnet and an electromagnet. O What tools and procedures were used to test the design features of your prototype? O How can electricity be produced using a magnet and wire coil? O What are the basic principles of an electromagnet? O Compare and contrast the Earths magnetic field to that of a magnet and an electromagnet. Engineering Green Toys Challenge What was your favorite toy to play with as a child? Was it Mr. Potato Head? What about a Slinky or Legos? It seems like every time you walk through the toy section of a store the toys get cooler and more exciting. Who comes up with this stuff? Toy engineers, thats who! As a toy engineer, you can play with toys all day long while trying to create new inventions that kids will love. If youre not really good at coming up with new things, you can also find new ways to make old favorites more exciting! Engineers have a wide range of opportunities from streamlining the production process, to testing toys for safety and durability, to designing the packaging. Your challenge is to design and create a toy that uses batteries, solar power, hand-held generators, or solenoid magnets to function. Toys that must be plugged into wall outlet are NOT acceptable; these toys should be environmentally-friendly. In order to do this, you must understand and be able to explain the relationship between electricity and magnetism as you construct and analyze electrical circuits. The electrical toy must also be safe and cost-effective. Finally, your team will also design and create the packaging for your environmentally-friendly toy. Restate your problem State what you already know List any limitations or controls O Research the following topics: O Types of circuits (series & parallel) O Action Research: series circuits vs. parallel circuits O Electron flow (current) O Batteries O Electromagnets O Action Research: Make an electromagnet. How do you build your own motor? O Solenoid O DC motors O Solar Panels O Toy Engineering O Autodesk 123D & 3D printers O Brainstorm ideas with your team for each problem O Decide on a toy that your team will design and create. O Draw a detailed blueprint of your toy. O Make a materials listjustify ALL materials! Dont forget packaging. O Make list of steps you will take to engineer your toy, including packaging. O Create your design using Autodesk 123D Design. O Assemble your toy. O Test the functionality of your toy. O Write down what happened when you tested. O After testing, improve your design. O Make note of the improvements your group made? O What happened when you re-tested? Did you have to improve again? If so, how did you improve?
