In this activity,
members of your group will build inclinometers, devices that let
them measure the height of a distant object. That object can be a flagpole,
a building, a treeor a rocket!
inclinometers and learning how to use them prepares your group for making
rockets (Bottle Blast-Off!) and
measuring how high they fly. It can be tough to get a group of young people
excited about measurements, angles, and math. On the other hand, its
easy to get them interested in launching rockets and flying kites.
If you live in the
Northern Hemisphere (that is, anywhere north of the equator), people can
also use their inclinometers to figure out where on Earth they are by
measuring the height of the North Star.
So youll need
another way to measure distance. You could use a measuring tape, or measure
the distance with string, then measure the string with a meter stick.
If you have time,
we suggest that you make an inclinometer before introducing this activity
to your group. Putting together the inclinometer will only take you a
few minutes. Its useful to have a completed inclinometer on hand
to show your group.
We'd like your feedback on Math Explorer activities.
