Episode Description:

This is the 9th of 27 TV show episodes to teach kids (about 5th grade and up) programming using Scratch 2.

This episode:

1) introduces String Expressions,
2) displays the range of color shades, and
3) shows a way to use transparent color.

String expressions are introduced. Strings values are "X", "Yes" and "Cat". They are a fundamental data type since a lot of data is text strings. Also, the "join", "length" and "letter" operators are introduced.

The first challenge also introduces "Off by One" errors - an error situation that is common to all programming - not only in Scratch.

The second challenge draws large dots on the stage showing Scratch's range of colors and shades.

The final challenge shows an example of the transparent color that makes sprite costume areas colorless so they are see-through.

Episode Short Description: Introduces String Expressions, displays the range of color shades, and shows a way to use transparent color.
