Year 8 Computer Science

A dance can be compared to ........... in computer science

• a set of random instructions
• an algorithm

A subroutine is a set of instructions which are ...

• written to help decision making
• written to simplify the code and make it easier to understand
• part of the main program
• used for making costume changes

What sort of graphics has this student used to create her sprite?

• Bit map graphics
• Holistic graphics
• Java script
• Vector graphics

When the space bar is pressed what will happen after 3 seconds?

• The music will start
• Switch to costume 2
• Switch to costume 5
• Nothing will happen because there is a bug in the code

Which set of pieces will you look in to find out how this student has written her sub-routine called 'Dance'?

• Motion
• Control
• Events
• More blocks

What will happen if letter t is pressed once the green flag has been clicked?

• Something will be rotated 90 degrees clockwise
• Something will be rotated 15 degrees anticlockwise
• A horse sprite will jump 15 degrees
• Nothing at all as there is a bug in the program.

What will happen when the computer reaches the piece called 'Dance' in this computer code?

• Control will pass to a sub-routine called 'Dance' and will then return to the main program once the sub-routine called 'Dance' has finished
• The program will stop at this point

A student has been 'tinkering' with making decision structures. What will happen when she runs the code and selects '2'?

• Nothing at all as option 2 hasn't been defined.
• The sub-routine 'rollyhead' will start
• The sub-routine 'ShakeyLeg' will start
• None of the above as there is a bug in the code.

A student is working on building a simple animation sequence. Which coding piece would she use to make the figure's head appear to move?

• A motion piece
• A next costume piece
• A decision piece
• A sensing piece

A dance set to music is being choreographed for a competition. In order to decompose the dance into its constituent moves which of the following couldn't be used?

• An algorithm
• A flow Chart
• A random list of instructions in no particular order
