Editor's Notes

  • Briefly talk about the use of images and copyright. Remind them they need to have permission to use any images they find on the internet. Show the short video about creative commons.

    https://www.commoncraft.com/video/copyright-and-creative-commons

  • Explain the difference between vectors and bitmaps. Hyperlink on image above to http://www.bbc.co.uk/schools/gcsebitesize/dida/graphics/bitmapvectorrev3.shtml – simple grid which compare bitmap and vector graphics

    Bitmap or vector graphic?
    When deciding whether an image should be a bitmap or vector graphic, you should ask yourself the following questions:
    Does the image need to be resized?
    Does the image need to be drawn to scale?
    Do you need the image to look real?
    Do you have any restrictions on the file size?
  • Show the Paint Editor Tips video Differences between vector and bitmap
    http://scratch.mit.edu/help/videos/#Paint%20Editor%20Tips

    Encourage them to explore the tools by drawing an apple
  • Use My Studio collection – Anyone for Ice-cream – exploring vector graphics- The instructions are in the notes and credits on the project page
    http://scratch.mit.edu/projects/34767470/

    Look at the costumes for the ice-cream cone. How has it been drawn? Enlarge the cone and use the ungroup tool to see the shapes within this shape. Explore the duplicate shape tool to see how the waffle pattern has been created.
    Look at the fill tool and how the graduated colours have been achieved.
  • Quickly look at these costumes changes and the very simple script used to create simple movement

    TASK
    Draw a character. Duplicate the costume several times and make small changes on each costume. Create a simple script to animate it.
