2. Construct a simulation of the 2004 transit:
using modeling material (clay Playdoh, etc.) form a ball
b. Place Venus models on a thin stick and anchor to block
of wood or other material.
c. Mount a large piece of paper on the wall.
d. Place the Venus model in front of light source so that
it projects a small shadow on the circle of light projected
from the light source.
e. Move the Venus model in small increments simulating
the times listed in the http://sunearth.gsfc.nasa.gov/eclipse/transit/venus/city04-1.html
3. Students compare their observations to those that took
place in earlier transits.
this brief story of Jeremiah Horrocks and compare his methodology
of projecting the image through a telescope onto a card with
the simulation in this lesson.
From Wikipedia, the free encyclopedia.
Jeremiah Horrocks (1617 - 1641), sometimes given as Jeremiah
Horrox, was an English astronomer, born in Hoole, Lancashire,
United Kingdom. His father was a small farmer.
At Cambridge he became familiar with the works of Johannes
Kepler, Tycho Brahe, and others. Horrocks was convinced
that Lansberg's tables were inaccurate when Kepler predicted
that a near-miss of the transit of Venus (when the planet
Venus can be seen from Earth as crossing in front of the
Sun) would occur in 1639. Horrocks believed that the transit
would occur, having made his own observations of Venus for
Horrocks focused the image of the Sun through a telescope
onto a piece of card, where the image could be safely observed.
From his location in Much Hoole, Lancashire, he calculated
that the transit was to begin at approximately 3:00pm on
November 24, 1639. He first observed the tiny black shadow
of Venus on the card at about 3:15pm.
His observations allowed him to make a well-informed guess
as to the size of Venus, as well as to make an estimate
of the distance between the Earth and the Sun. His figure
of 59,000,000 miles was far from the 93,000,000 miles that
it is known to be today but it was a far more accurate figure
than any suggested up to that time.
