 | Procedure Part 1:
- Pair students up into groups of two.
- Display a large amount of resources and reference materials that are
available to the students.
- Tell students that they are to develop an oral presentation about space
shuttles and when they were developed, and why. They must also talk about
one individual launch and tell about the speeds that the space shuttle
reached.
- Give the students about 45 minutes to do this, this should be enough
time because of the amount of materials that were provided to them.
- Student must develop a way to display the information that they learned
on a poster board, and then they will use the poster board in their oral
presentation.
Presentation assessment (use this
to assess the oral presentations each pair.
Part 2:
- Take the string and run it through the shuttle so one end comes out the
nose and one end comes out the tail.
- Tie one end of the
string to the wall (or any sturdy object that will not move)
- Have a student hold
the other end of the string
- From
the highest point possible, have a student release the shuttle
- Time the movement of
the shuttle from the release to the landing
- Measure the distance
from the wall (or object) to the landing site
- Now we computer the
average speed by writing a fraction using the Total Distance to the landing
point as the numerator and the Flight Time as the denominator. Average
Speed is written as a unit rate. To find the unit rate, we divide the
denominator in to the numerator. (the units will be inches/second)
