Subject: Build an Interplanetary Scale in this month's Science Scope
Date: Thu, 12 Dec 1996 09:53:37 -0600
Dear discuss-lfm members,
This month's Science Scope (an excellent NSTA Journal for middle
level science educators) has an article called "Build An Interplanetary
Scale" this month. It is by Catherine Matthews (assistant professor
of curriculum and instruction at the U of NC at Greensboro and Dick Fargo
(vice principal of Lakes Middle School in Couer d'Alene, Idaho and Jeffrey
Craig,
education director at The Discovery Center in Boise, Idaho.)
The activity "helps students understand mass, weight, and gravitational fields
with an interplanetary scale. Students can simulate their weight on any planet
or satellite with a surface gravitational field equal to or less than Earth's."
The procedure is clearly written and easy to implement in the classroom... I can
just see all of you borrowing bathroom scales from your colleagues!
Thought you might be interested in this particular activity as it relates
to the Live From Mars.
