How far does this block make the robot move?
Set your Finch so its tail is at the end of your ruler (at 0 cm). Then run the program below and measure how far the tail moves.
Next, change the number in the forward block. Try out different numbers between 1 and 10. Measure how far the robot moves for each number.
Can you use your measurements to figure out how many 8 blocks you would need to move 50 cm (or 20 in)? Make a prediction and then write a program to check your answer.
