| Lesson Plans:
The Formation of the Solar System
Any model of the formation of the solar system must account for the
motions, compositions and locations of all the planets and their
moons. In this lab, you will use the motions of objects in the solar
system to concoct a model of the formation of the solar system.
Celestial Navigation
The gnomon, a fancy name for a vertical stick (must be thin and
round) stuck in the ground, is the most ancient of all astronomical
instruments. It can be used to chart the Sun's motion across the sky
so as to determine one's latitude and longitude, as well as the time
of true noon.
Sidereal Day
To find the difference between a solar day and a sidereal day you
will measure the intervals between the times when a star returns to
a given spot over successive evenings.
Motion of the Moon
The moon changes its position in the sky from day to day as a
consequence of its orbital motion around the earth. In this project,
we ask you to chart the motion of the moon against the background
stars.
Kepler's Laws
By reproducing ellipses via the "string-and-pencil method," the
students will draw ellipses and determine the eccentricities; by
measuring the orbits of five of Jupiter's moons, the students will
test Kepler's third law; and by using characteristics of Pluto's
orbit, the students will confirm Kepler's second law.
How Old Are You?
To understand the relationship between planetary orbits around the
Sun and our measure of time.
How Much Do You Weigh?
To understand that weight is a measure of gravitational attraction
and that this force is not the same on each planet.
