1. Traveling on Various Surfaces Over Various Time Periods

2.  Can You Name Different Types of Surfaces?

3.  Does the various surfaces that a robot travels on have an effect on its Speed?

4.  Wood  Floor Tile  Carpet  Metal  Paper  Cardboard  Dirt  Concrete  Tar  Grass  Any more??????

5. Z oooooooooo m……..

6.  Speed is often referred to as the RATE an object or your Taskbot moves.

7.  It is related to DISTANCE and TIME.

9.  Distance are units of length between two points or places.  Metric lengths include: cm, meters, kilometers.  Customary lengths include: inches, feet, yards, miles.

11.  Time is how long did it take to go from one place to the other.  Some time is measured in seconds, minutes, hours, days, months, years.  Any other ??????

13.  Distance = Rate multiplied by Time [D=RT].  Soooooooooooooooo  Rate or Speed = Distance divided by Time.

14.  Program the Taskbot using the LEGO NXT Software and learn how to change a robot’s speed and time variables.  Make predictions about the distance your Taskbot will travel for given time periods.  Compare a robot’s speed over different surfaces.  Test/measure the distances (your predictions).  Compute and graph the robot’s speed(rate).

16.  Decide what surface you want your robot to travel on. Enter the description in Column 2.  Predict the distance that your robot will travel. Enter it in Column 3.  Fill in the time that you choose in Column 5.  After your robot travels, fill in Column 6 with the distance that you measured.  Compute the rate and complete Column 4.

17.  Try many trials with different times.  Try many trials with different surfaces.

18.  Groups present their finding and graphs.  Any observations, discoveries, conclusions?  NXT program sharing………………

19.  Sooooooooooooooooo  How are Speed (rate), Time, and Distance related ?????? What would you like to try NXT ??????
