Question

define variable block

define Sensing block

define pen block

define motion block​

Answer 1

Answer:

1. Think of a variable as a place to store a value in the NXT's built-in memory. Other programming blocks can read the variable's current value (and even change it) by connecting to the block with data wires.

2. Sensing blocks is one of the ten categories of Scratch blocks. They are color-coded cyan, and are used to detect different factors of a project. There are currently 18 Sensing blocks: 3 stack blocks, 5 boolean blocks and 10 reporter blocks.

3. Pen Blocks. The Pen is a feature in Scratch that allows a Sprite to draw shapes, plot colored pixels, and so forth on the screen with the pen blocks. The pen is derived from Logo's turtle graphics, as are the motion blocks with which the pen is used.

4. Motion blocks is one of the ten categories of Scratch blocks. They are color-coded medium-blue and are used to control a sprite's movement. They are available only for sprites. There are currently 18 Motion blocks: 15 stack blocks and 3 reporter blocks.

Answer 2

• Variables blocks are one of the ten categories of Scratch 3.0 blocks. The variable blocks are color-coded orange, and the list blocks are color-coded dark red. There are currently 17 Variables blocks: 11 Stack blocks, 5 Reporter blocks, and 1 Boolean block. There are 5 variable blocks and 12 list blocks
