Tuesday
Run part of the flight
Today the crew runs two test flights.
The ship flies over a wide, empty field.
Nova keeps the logbook the whole time.
Raven wants to run just part of the flight.
What if the ship flies only 4 steps?
Rocket says, let us see what happens!
- Read the lines.
- Tap the answer.
The same drop, every time
At spots 1 to 4, height stays 3.
At spot 5, the ship drops to 1.
Then it lands softly on the grass.
Test 1: stop after 4 steps
Rocket changed repeat 5 to repeat 4.
Now the flight stops after 4 steps.
Keep a logbook for steps and height.
set height to 3 set steps to 0 repeat 4 times: move right change steps by 1 do check height stop land
- Track steps and height.
- Tap the answer.
Test 2: start at step 3
Test 2 skips ahead to the end.
Steps starts at 3, then two steps run.
Build test 2 yourself.
Set both boxes first. Then two steps.
- Set both boxes first.
- Then count and check, two times.
What do you notice?
No drop while steps is 4 or less.
The drop comes when steps is 5.
