III Learning Activity Context
Context: Moving TekBot
Abstract: Place a tape measure on the floor. Start
stopwatch
once TekBot begins moving forward from start line. Stop TekBot when
time
reaches 6 seconds. Write down result.
IV Teacher and Student Suggestions/Tips
Make sure students take their measurements from the same
place
on the TekBot (if they start measuring from when the bump sensor
crosses the starting line, finish timing at the bump sensor)
V Teacher Questions
Now that we know how far it went in 6 seconds, how do we
figure out how many inches per minute the TekBot moved?
How will we convert inches per minute to MHP? Is there more
than one way to accomplish this? How many steps do you think it will
take?
VI Assessment Ideas
A worksheet could be handed out with space to work out the
math. Stress that the students show their work because there might
be many different ways to solve the problem. There could be a place
at the top for a guess at how many miles per hour the TekBot travels
and then they can check to see how close they were to their
estimate.
