What is a GIF?

• A tool for drawing shapes

• A type of file that shows moving pictures

• A kind of sound file

• 
  A type of file that shows pictures

What is the difference between a GIF and a video?

• GIFs are long animations with no sound, while videos can be long and have sound

• GIFs are short animations with sound, while videos can be long and have sound

• GIFs are short animations with no sound, while videos can be long and have sound

• GIFs are short animations with no sound, while videos are shorts and no sound

What is an advantage of using GIFs?

• They have big file size and are easy to share

• They have a small file size and are easy to share

• They have a small file size and are not easy to share

• They have a big file size and are not easy to share

How is a GIF formed?

• By separating a series of videos to create an animation

• By separating a series of images to create an animation

• By combining a series of images to create an animation

• By combining a series of videos to create an animation

What should we do if we want a GIF to look smoother in Scratch?

• Increase the number of frames in the GIF

• Decrease the size of the GIF

• Use fewer colors in the GIF

• Change the GIF into a still image

What is the function of this code?

• It changes the background every 0.1 seconds.

• It moves the sprite to the next position every 0.1 seconds.

• It changes the sprite’s costume every 0.1 seconds, creating an animation.

• It makes the sprite disappear after 0.1 seconds.

What happens if you set a very long wait time between GIF frames in Scratch?

• The animation will stop

• The animation will appear slower

• The animation will reverse

• The sprite will disappear

What is the main purpose of the "next costume" block when used with GIFs in Scratch?

• To move the sprite across the stage

• To change the sprite's size

• To create the illusion of animation by changing costumes

• To stop the animation

What will happen if you forget to add a "wait" block between "next costume" changes in Scratch?

• The GIF will play slower

• The GIF will play too fast

• The GIF will disappear

• The GIF will not play
