Research Tasks
You must make a presentation to the United States Congress
in Washington, DC, to explain why you believe that your comet rendezvous
mission should take place. This mission will cost plenty, and you need
to make
your
case that space travel - especially travel to a comet - is well worthwhile.
If you can state your case well, your mission will be funded and you
will soon Rendezvous with a Comet. Remember, you are part
of a team of teams. Each team must contribute a small part of the puzzle
so that the Congressional leaders can get the "big picture." There
are eight
teams scheduled to go on the Rendezvous mission
if it
is funded.
As a group and as individuals teams, you
must present information and then answer questions about the mission
asked by the Congressional committee. (One representative from each team
will
be asked to make a general presentation.) Then, each team (including
all team members)
will
make
its own presentation
dealing with its part of the mission.
GENERAL PRESENTATION OUTLINE:
- What do we know about comets?
- What more do we need to learn about comets?
- Why is it important to study comets?
- Why is this Rendezvous with a Comet mission important?
TEAM PRESENTATIONS OUTLINE:
- What is your team?
- What are your team responsibilities during the
mission?
- How will you accomplish those responsibilities during the
mission?
- What equipment will you use?
- How will you work as
a team?
- What knowledge/skills do you now have that shows
you are ready for your part of the mission?
- Why is your team so important to
the success of the overall mission?
- Why do you need to go on the
mission with the rest of the crew?
- What will happen if nobody is
on the mission to do the work of your team?
PREPARATION:
To prepare
for your
presentation
before
Congress, all teams
are require
to work together as a single group to find answers to the following background
questions based
on different degrees of difficulty and the work of different teams.
Basic questions are designed for all
students
in grades
5-8;
intermediate
questions are designed primarily for students in grades 6-8; advanced
questions are designed primarily for students in grades 7-8.
Basic Level: Find answers to all these
questions:
- What are comets?
- Where do comets come from?
- What are the 3 main parts of a comet?
- What does a comet look like?
- Why do comets have tails?
- How are the tails of comets formed?
- What are the main ingredients of a comet?
- What are the names of
5 famous comets?
- Where do comets get their names?
- What is a comet's path
around the sun like?
- What is magnitude?
- What is eccentricity?
- What is pulse?
- What is blood pressure?
- What is humidity?
- What is pH?
- What is an electrical circuit?
- How are probes used during space
missions?
- What is meant by “density"?
- What is the
mathematical formula for finding density?
- What is chlorophyll?
- What is radiation?
Intermediate Level: Answer all questions
above plus the following:
- When were the first comets discovered?
- What famous superstition
is related to a comet?
- How can we determine the orbits of comets?
- How do comets come to our solar system?
- How do comets form?
- Why do comets have two tails?
- Why are the two tails of comets different
colors?
- What are sun-grazing comets?
- How do astronauts describe the position
of objects in space? (Hint: They don’t use latitude and longitude,
but they have a different system of numbers.)
- What is triangulation?
- How do the pulse and blood pressure of
astronauts change when they are in space?
- What
happens when humidity gets too low?
- What could happen when humidity
gets too high?
- Why is air pressure very important
to astronauts in space?
- How could
you find the volume of an irregularly-shaped object?
- List 3 sources
of good radiation and 3 sources of harmful radiation.
- List 3 insects
that would be beneficial to plants in
a greenhouse.
Then, list
3 insects that would
be harmful to plants
in a greenhouse.
Advanced Level: Answer all questions
above plus the following:
- How do we study the composition of comets?
- What is the difference
between perihelion and aphelion?
- Why are comets more likely to break
apart at perihelion than at aphelion?
- Why are comets generally brighter
a few weeks after passing perihelion than a few weeks before passing
perihelion?
- How do comets change over time?
- What evidence do we have that the
moon, earth, and planets are sometimes hit by comets and asteroids?
- Formulate
a hypothesis which could connect comets with water in our oceans.
- Some
people thought that if Earth passed through the tail of comet,
it would have deadly effects
on human
health. In
1910 the
Earth passed through the tail of Comet Haley.
Construct a scientific argument in favor of or not in favor
of this concern.
- If you wanted a probe to collect
particles from a comet and then return to Earth, which
part of
the comet
would
you want the
probe to go through? Why?
- Why is it important
for astronauts to have acceptable visual and auditory reaction
times while in space?
- Why is it extremely important to test
the drinking water of the astronauts aboard
the
Space Station
to make sure it
is clean?
(Hint: Where does their water come from?
What happens if they run out of water?)
- What
is the difference among: meteors, meteorites, and meteoroids?
