Discussion questions
Talk about it
A thrown dart follows a predictable curved path. If a computer measures its motion quickly, it can calculate the landing spot and move the board there.
- How can the machine 'know' where the dart will land before it gets there?
- Why does a thrown object follow a curved path instead of a straight line?
- What steps of the design do you think were hardest to get working?

Vocabulary: trajectory, predict, motion, sensor.
Try it: Toss a ball of paper to a friend and watch its curved path. Draw the arc and mark where it lands.
