d= rt

D = Distance R = Rate or Speed and T = Time

Now that you have the ability to measure the duration of events return your focus to building a navigational device.

Starting Points: Hopefully these directions make more sense!!

• Consider moving your Navigational Out of the Forever Block so that you can show OTHER things on your LED Buttons

• Can you tell the captain how long she traveled in a certain direction?

• Can you ask the captain to enter a speed of travel

  • How might I do that?

    • set a starting speed of say 6 MPH

    • let the captain hit the A button or Shake the Micro: bit to increase the speed by 1 MPH per event

    • change the speed to be equal to the number indicated by the captain

      • so if speed starts at 60 MPH and he hits the A button 5 times then the speed is 65 MPH

    • So you know how long she traveled, and now you know she traveled 60 MPH

    • d = rt! You can tell him how many miles per hour he traveled in a certain direction

      • d = distance

      • rate = speed

      • time = duration or time elapsed

      • So you can tell the Captain how FAR they traveled based on how long they traveled and how fast they traveled

    • Can you convert MPH to knots since that his the language captains use?

• Can you allow the captain to choose between N S E or W as the desired direction by rotating the micro:bit?

• Can you help the captain head 1 direction for a certain number of seconds

• Can you incorporate the next 4 directions?

• Can you help navigate from ONE place to another?

  • travel North for 1 minute

  • Turn East and travel for 6 minutes?

• Can you design how this would be mounted on the captain? on the boat?

Um...how fast do boats travel
