Computer Science

Unit 7: Black and White Images

Throughout this unit, students gradually discover how to use bits to represent more complex data types. In this case, students work on representing images using sampling. Students quickly realize that very tiny sample squares are needed to approximate an image’s curves and small details.

Unit 8: Color Images

This Unit continues the story of how bits are used to represent digital images. Students will use the Pixelation Widget to attempt to make digital approximations of analog images, this time in color. These images are produced using layers of abstraction, with each layer relying on the other to perform its process.

Unit 9: Lossless Compression

Students use the Text Compression Widget to experiment with compressing songs and poems and try to find their ‘personal best’ compression. As a wrap-up, students discuss what factors make some texts more compressible than others.

Unit 10: Lossy Compression

Students will be able to examine the effects of lossy compression on text & images. Given a piece of media, decide whether to use lossy or lossless compression based on the needs of a situation.

Unit 11: Intellectual Property

Students have been examining how digital information is created and stored, but they have not closely examined the question of who owns their digital data and what rules govern how that information can be shared.
