In this activity you will play a game that tests your reaction time so pay attention and see how well you do.




Go to the Zap! activity. Then click on the "How to Play" button at the top left of the screen before playing. Scroll down the page using the arrow key to read all of the instructions for the game.

As you read, be prepared to answer these questions:

  • What is the goal of this game?

When you're ready, click the "Back to Zap!" button at the top left of the screen to return to the interactive. Then click the red Zap! button toward the bottom of the screen to start.

Remember: At the end of each round, the reaction-time scores will be displayed again. Do not click the Zap! button until your partner has written down all of your reaction times!

When both players are finished and scores recorded, click on the "Learn More" button at the top right of your screen. Use the arrow buttons to scroll down the screen and read more about what's happening in this interactive.
