The lab door locked behind you!
A turtle has scrambled the exit code. Five locks stand between you and freedom — each one is a challenge from yesterday's lesson on algorithmic thinking. Solve a lock and it reveals one digit of the vault code.
Work with your partner. Every teammate must be able to explain every answer — the lab keeper (Mr. Babb) may quiz you before you're truly free!
Beat 8:00 for bragging rights. Wrong answers cost time, not points.
Predict the exact drawing
The lab turtle starts at the green dot, facing east, pen down. It runs this program. Which drawing comes out?
Click the line with the bug
Python refuses to open the lock. Read the error, then click the guilty line:
Decode the definitions
Match every definition to its term. All four must be right at once!
Which algorithm draws this shape?
The lock wants exactly this shape — an equilateral triangle with sides of 100 pixels:
Put algorithmic thinking in order
Click the cards in the order they happen, from first to last. One wrong click resets the lock!
Enter the 5-digit vault code
Type the digits you earned, in lock order (1 → 5):
