Welcome to the SpeedRacer page. In this activity we will learn how to use Scratch and how to control the speed of our cars.
Here are the steps to follow:
Complete the online survey about speed
Create a new Scratch project
Create a background that is a racing track (top view)
Change Sprite1 to a car
Create a script to turn your car left and right with the arrow keys
Create a script that starts the car moving forward when the green flag is clicked
Test your game
Change the speed of your car with the up and down arrows (add a variable)
EXTRA: Measure the time and distance it takes to go all the way around the track - calculate your average speed.
