Objectives:

  • Demonstrate gracious professionalism when working as part of a team.
  • Learn how to use the Scratch programming interface (video)
    • Experiment with the distance and/or tilt sensors as input devices for Scratch.
    • http://info.scratch.mit.edu/WeDo/StarterProjects
    • Try one of the programs for each device and experiment with changing the program to see what else you can make it do.
  • Build the "Roaring Lion" using WeDo components.
    • Program the "Roaring Lion" using Scratch or WeDo programming language
    • Incorporate a distance and/or tilt sensors as input devices
    • Program the lion to lie down and eat when you throw it a bone
  • Analyze the "Roaring Lion" as a system

In-class extension:

  • Design an appropriate habitat for your lion using the drawing tools in Scratch. Plan a skit where your lion is the main character. Take a screen shot for the class wiki photo gallery or make a short video to post on the class wiki.

Other Extension Activities:

You might want to try one of these extension activities (optional):
  1. Find out where real lions live. What are their habitats like? Draw a picture or write a short story about it. Or you can create a wiki page!
  2. Check out some programs other kids have made using Scratch. http://scratch.mit.edu/channel/featured Which program did you like the most? Why?
  3. For our last class we will be sharing some creations with your parents that use Scratch and WeDo. Write down some ideas for what you might like to design. What sensors would you use? What could you do with the Lego WeDo motor? Could you use the Scratch and WeDo components to tell a short story? If your parents download the Scratch program (see instructions on resource page) at home and you create a program on your own, you can use the same file in class. The easiest way to share is to upload the file to the Scratch website. Your parents can help you make an account.
