scratch challenge 3 and 4.

in challenge 3 we had to make the bat switch from costume to costume to give an illusion of flying, and in challenge 4 we had to make the bat appear as if it was flying towards you by changing the size.

scratch challenge 2.

i have designed an animation where there are fish swimming around and when they come n contact with the shark, the shark closes its mouth giving the illusion of it chomping them, and they disappear for a few seconds, giving an illusion of them being eaten.

here is the script for the shark;

here is the script of one of the fish;

here is a screenshot of the animation;

• key moves
• move to a beat
• moving animation
• reference guide
• say something
• getting started
• surprise button
• animate it
• change colour
• dance twist
• follow the mouse

• interactive whirl

flowchart questions.

1. For each of the flowcharts below describe in words what you think they will do.

In this flowchart, it shows the process of printing temperature. It begins by reading the temperature, it then deciphers whether the temperature is below 32, if yes, it prints "below freezing", if not, it prints "above freezing".

This flowchart demonstrates the one second response to a switch. When the switch is on, LED will be turned on, after one second, LED is turned off and the timer is reseted.

2. Convert one of the algorithms you have created in the previous task into a flowchart.
