Traveling on Various Surfaces Over Various Time Periods

 Can You Name Different Types of Surfaces?

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

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

Z oooooooooo m……..

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

 It is related to DISTANCE and TIME.

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

 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 ??????

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

 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).

 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.

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

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

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