Bell Work: 3/3/15 O List your ideas for a “green” toy. Explain what makes each toy the best engineered toy. Get with your team and compare ideas.

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 Earth’s 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 Earth’s 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, that’s who! As a toy engineer, you can play with toys all day long while trying to create new inventions that kids will love. If you’re 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.

Let’s create a “class” circuit! Can we get energy in the form of electrons to flow through our entire class to complete a circuit?

Reflection O What type of circuit did our class create? O How were we able to create this type of circuit? O Why didn’t it work when two hands were dropped/let go?

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: 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
