Labs from YSI 95.
Here are some of the labs and lesson plans used by instructors during
the Yerkes Summer Institute (YSI) in August 1995.
Important Disclaimers and
The schedule from
YSI 95 is on-line. There are also several
pictures of the labs
and final student reports on line.
- Calculating The Moon's
- (night lab, taught and adapted from Project
SPICA by April Whitt)
We indirectly measure the width of the moon.
- The Grating
- (day lab, written and taught by Jim Sweitzer.)
We learn about grating, diffraction, waves, and interference.
- How Bright are the
- (night lab, written and taught by Todd Duncan and Al
We learn how to use the brightness of stars to determine how much
energy is reaching us from them.
- Predicting the Configuration of the
Satellites of Jupiter.
- (night lab, written and taught by Rich Kron and Rich
We plot the current positions of the Galilean satellites and make a
scale model that fits in a window in the main building; we then look
at the real thing (if it's clear) and our model in the other building
with the 10-inch.
- Shadow Observations.
- (day lab, taught and adapted from Project
SPICA by April Whitt)
Using a plastic film canister as a gnomon, we record
shadows at specified times during the session, which we then compare
with shadows recorded at the same times from different
- How much energy does the Earth
receive from the Sun?
- (day lab, written and taught by Todd Duncan)
By using the Sun to heat up some coffee, we determine how much energy
the Earth receives from the Sun.
- Studying the Sun and
- (day lab, taught by Rich Dreiser)
We learn about the Sun and sunspots, and we make observations of
the Sun with the 10-inch.
- Sun's Path.
- (day lab, taught and adapted from project STAR materials
by April Whitt)
We use clear plastic hemispheres and markers to record the apparent
motion of the Sun across the sky. Plastic hemispheres for this summer
were donated by Greg Gansz of Learning
Technologies, 59 Walden Street, Cambridge, MA, 02140, phone
- (day lab, written and taught by Rich Kron)
We build a telescope and learn about magnification, fields of view,
and seeing, among other things.
- Transmitter Hunt.
- (day lab, written and taught by Chris Knox)
Using a very neat transmitter Mr. Knox designed with the chip from a
recordable Hallmark card, the students learn about interference by
going on a transmitter hunt.
