• Go straight in 3 different ways.

• Turn in 3 different ways.

Multiple Choice

Which two codes cause EV3 to go the same exact distance?

Multiple Choice

What does this code do?

• It moves EV3 backwards then stops.

• It moves EV3 forwards then stops.

• It waits until distance is less than 6 cm.

• It moves forward until it detects an object less than 6 cm away then stops.

Multiple Choice

What does this code do?

• It moves EV3 backwards then stops.

• It moves EV3 forwards then stops.

• It moves EV3 backwards then stops when it has travelled more than 6cm.

• It moves EV3 forwards then stops when it has travelled more than 6cm.

Multiple Choice

What does this stack do?

• It drives then stops when it detects and object.

• It drives until it detects an object closer than 6cm.

• It drives until it detects an object closer than 6cm, then it goes backwards until it has driven more than 6cm away from the object.

Multiple Choice

What does this do?

• It makes an apple banana sauce.

• It joins the word apple with the word banana.

Multiple Choice

What is the result of this calculation?

• 4 cm

• The distance from an object as a number joined to " cm"'.

Multiple Choice

What does this code do?

• In the display it writes the word, EV3 starting at pixel 1 , 1 (top left corner) with a normal black font.

• It says EV3.

Multiple Choice

What does this do?

• It writes '"join 4 distance in cm"" at 40,60.

• It writes in the display the distance to an object.

Multiple Choice

What does this code do?

• It writes 4 cm forever.

• It updates the distance on the display constantly.

Multiple Choice

What does this code do?

• If the distance to an object is less than 15cm, it plays a beep.

• If 4 is the distance to the object, it plays a beep.

Multiple Choice

What does this code do?

• It joins 4 and cm together and plays beeps.

• It displays the current distance measured and makes a sound when anything gets close.

Multiple Choice

How would you write code to play a beep louder and faster the closer you get until you are too close and play a steady beep?

¿Cómo escribirías un código para reproducir un pitido más fuerte y más rápido a medida que te acercas hasta estar demasiado cerca y reproducir un pitido constante?

Multiple Choice

What does this code do?

• Writes the distance on the display and plays a louder sound the closer it gets.

• Writes the distance on the display.

Multiple Choice

What does this code do?

• Sets the volume quieter the closer the distance is.

• Plays a beep louder the closer it gets to an object.

Multiple Choice

Which code cause EV3 to write the distance and play it louder and louder the closer it gets to an object?

¿Qué código hace que EV3 escriba la distancia y la reproduzca cada vez más fuerte a medida que se acerca a un objeto?
