Dear discuss-lfm members,

Thought I would share the >>results<< of Challenge Question
#4 with you and remind you that Challenge Question #6 
are due tomorrow!  

Teachers have been telling us (referring back to the vocabulary of CQ 
#1) that they think it's very useful for students to compare Earth's 
"geology" and Mars' "areology." Now, in preparation for some of the 
content of LFM 102 (aired April 24), a more open-ended 
question, which will require and receive some subjective, but fair, 
judgments from our PTK/Live From Mars CQ staff!

CQ #6: What five features make Mars most like Earth? And, what 
five features make Mars most unlike Earth?

We hope students will come up with some geologically correct 
answers, but also with some clever, provocative and tongue-in-
cheek comparisons!

You are invited to send original student answers to: Please include the words CHALLENGE 
QUESTION in the subject line of your email. The kids' names will be 
listed online and token prizes will be given to those will the best 

Answers are due April 30th!  Challenge Question #5 Results to
be posted shortly!

Olympus Mons is the highest feature on Mars. What is its 
counterpart  on Earth? Be forewarned: it is not Mount Everest!

If you measure Mauna Kea, Hawaii, from ocean floor to peak, you will 
find that it is higher than Mt. Everest, Nepal -- about 30,000 feet 
compared to Everest's 29,000 feet.

If you think about how astronomers measure the height of features 
on Mars, you'll have a clue to help you answer this question. What do 
we mean?

For Mars, astronomers use the "datum level" -- the reference surface at
which atmospheric pressure is 6.1 millibars (the pressure at the triple
point of water) -- to give a baseline for measurement of altitude. On
Earth we use sea level, but as CQ#3 reminded us, that would currently be
impractical to do on Mars -- though some astronomers think there may once
have been an ocean on Mars, or at least lakes of liquid water, now lost to
space or locked in permafrost.

        RESULTS:  Challenge Question #4 -- four participants had
                  the answer 100% correct, so we drew a name for the winning
                  entry and RICK KIRST's 4th and 5th graders (Anastasia,
                  Marco, Jeff and Daniel) won the drawing.   

                  Congratulations to all who hit the answer right on the head!

                  Honorable Mention:  Mrs. Elaine Heines' Fourth Graders from
                        Palm Bay, Florida;  Linda Lund's Christian Academy
                        8th grade students; Katie, Ian and Jessie in Rick
                        Kirst's Class; Charlotte Steven's students (Ryan, Jason
                        Linsey, Billy, Chris, Diana, John, Michael and Paul);
                        and Darlene Taylor's Mesa Class.  All had correct
                        answers -- >great< work students!
