Name: |
Bow and Arrows
|
| Concepts / Skills
addressed: |
measurement, designing an
experiment, graphing, linear relationships, slope,
|
| Approximate Grade
Range: |
4th - 9th ?
|
| Materials: |
bow and arrows set, measuring
tape
|
| The General Idea:
|
There is some kind of a
relationship between the deflection of the bow string and the distance
of the arrows flight - the further you pull it back, the further the
arrow flies. So challenge your students to discover the
relationship and to be able to use the relationship
to predict the distance that will be flown for a distance that
you will provide. When I do this activity, I tape the bow down on
the table (This cuts down on a load of potential problems.) and provide
a measuring tape for them record the distance the arrow slides along
the table. I also tape a strip of paper marked in inches so
as to enable them to quantify the deflection of the bow string.
This set-up is similar to that for the Ramp
Racing activity in that you give them the materials and the charge,
let them experiment and gather data, clean up, analyze data and be
ready to make prediction for a deflection distance that you will
provide after, say 15 minutes (or overnight for homework) of number
crunching.
