WORKSHOP 3: SAIL CAR
Speed Is No Mystery
Remember how the potatoes fell very quickly from their starting point onto the spit
in the potato experiment? How quickly did they fall? What do we mean by words like
slowly and quickly, anyway? A snail creeps along at a snail’s pace, while a racecar
whizzes by at Indy 500 speed. What does speed mean? It is an indication of the
number of meters an object covers in a second. We could also say it specifies distance
traveled over a period of time. So it’s just a maer of dividing the distance traveled
by time.
What about Velocity?
Velocity is similar to speed, but it also takes into account the direction of movement,
not just the rate of movement.
Speed = meters (m) per seconds (s) = m/s
Speed = kilometers (km) per hours (h) = km/h
Speed = miles (mi) per hour (h) = mi/h
On these two pages, you can see
the paern for the sail. The solid
lines indicate where to cut with
scissors, the dashed lines indicate
where to fold, and the blue lines
show where to position the sail
struts.
1. Trace the sail template onto a
sheet of plastic (such as from a
thick trash bag) and cut it out.
2. Fold back the plastic at the
edges of the sail.
3. Secure the hems with tape.
4. Tape pre-cut sections of wooden
skewers to the sail to provide it
with a supporting framework.
