Navdha is playing a game created by her teacher using Scratch. The game works like this :

An item/thing name is shown on screen and then the screen shows moving images of multiple things/sprites. The player has to click on correct image/sprite as per displayed name. If the player clicks on correct sprite/image, a ball sprite in the right corner starts jumping and clap sound also plays. If the player wants to move to next thing/item, the player can press a space bar.
