Students Responses to Bald Eagle Challenge Questions # 1 & # 2:
Challenge Question # 1
"If you wore a backpack that weighed 2% of your body weight, how heavy would
your backpack be?"
From: ONTARIO
Hello, Our names are MATHEW HENNESSEY (29kg) and THOMAS CROTEAU (32kg).
If we had backpacks that weighed 2% of our body weight they would be:
MATT 0.58kg and TOM 0.64kg. We calculated these figures by multiplying our weights by 2% on a calculator.

1.7 lbs. I got my answer by multiplying my weight which is 85 lbs. x 0.02.

From: VERMONT My name is Matthew R. and I am a third grader at Ferrisburgh Central
School. First I weighed myself. Then I used a calculator to find out how
much 2% of my weight is. I weigh 70 pounds so 2% is 1.4 pounds which is
alittle under two pounds. Linda L. Thurber (lthurber@panther.middlebury.edu)
From: ILLINOIS
The answer: If I weighed 100 lbs., the backpack would weigh 2 lbs.I
transformed 2% to 0.02 because 2% is 2/100. Then, I multiplied 100 lbs
and 0.02. Then I knew it would weigh 2 lbs. Elisa Correa Mr. VanAntwerp's 6th grade classvJames Hart Junior High Homewood, IL Gary G Vanantwerp (GGVanantwerp@govst.edu)
From: ILLINOIS We thought that our backpack would weigh 1.4 pounds. We figured
that our average body weight was 70 pounds. Then we said 2% of 70 pounds
would be 1.4 pounds.vDr. Howard Elementary School Champaign, Il 61821 Cheryll Douglas (douglach@cmi.k12.il.us)
From: FLORIDAvMy weight is 65 pounds and the backpack is 1.3 pounds. OHS Science Lab (ohssci@gnv.fdt.net)
From: TENNESSEE Dear Journey North, I weigh 130 pounds. I have calculated that 2% of my body weight is 2.6
pounds. Therefore, a back on my back would weight 2.6 pounds.
Thank you, Jason Lisa McGinley (MCGINLEYL@ci.maryville.tn.us)
From: shannon walden We calculated that the backpack would wiegh 2.3 lbs. We multiplyed .02 x 115.

From: Shella DelCurtovHi from the Halfway Elementary Sixth Grade,
We dedided to use one students weight. The student weighed 80 lbs. We took
80x.02=1.6 for the weight of our backpack. (hescomp@pdx.oneworld.com)
From: MINNSESOTA My backpack would weigh 2.5 pounds (I weigh 125 pounds).

From: MASSACHUSETTS Patrick weighs 70 lb.So the backpack would weigh 1.4 lb.
James F Condon School, Boston Mass (condon@boston.k12.ma.us)
From COLORADO: "We had 4 people in our group. Our weights were 78, 147, 96, 100 pounds. We
calculated 2% of our body weight like this: 78 x .02 = 1.56 lbs. 147 x.02 = 2.94 lbs. 96 x .02 = 1.92 lbs. 100 x .02 = 2 lbs. That is how much backpacks that are 2% of our weight would weigh.

From: NEW YORK This is Gabriel Brotman, a member of the eagle team from Mrs. Berger's 5th
grade class. If I wore a backpack that weighed 2% of my body weight, my
backpack would weigh 2.44 lbs. Mrs. Berger showed us how to find a percent
of a number. I changed the 2% into the equivalent decimal, .02 , and then
multiplied my weight by it and got 2.44 lbs. Joan Berger, East Hills School, Roslyn, NY K12ROBZJ@vaxc.hofstra.edu
Challenge Question #2 "If the satellite goes around the earth every 101 minutes, how fast is it
moving?"
From: TENNESSEE Dear Journey North, We have calculated that the satellite is moving at a speed of 14,880 miles
per hour. We calculated the number of hours in 101 minutes (1.68
hours)and then we divided 25,000 miles (what we think is the distance
around the earth in miles) by 1.68 and got the answer 14,880 miles per
hour. Thank you, Jeff and Micheal

From: NEW YORK This is Gabriel Brotman, one of the eagle team members from Mrs. Berger's 5th
grade class. If the satellite goes around the Earth every 101 minutes, I
think that it would be traveling at about 248.32 miles per minute. I think
that the distance around the equator is 25,000 miles so I divided that
by 101 to get distance per minute.

From: MASSACHUSETTS We found our answer to be 23,629 km/hr. We took the circumference of the
earth at the poles 39,776 km and divided it by 101 minutes. We then
multiplied that by 60 and got our answer=23629 km/hr.

Floyd Haan (fhaan@iw.net)
The answer to the question about the speed the satellite is traveling
was 247 miles per hour. We found the diameter of the earth at the
equator which was 24,955 miles. That number was divided by 101.
