Question: If you wore a backpack that weighed 2% of your body weight, how heavy would your backpack be?
Answer: Well, luckily for the eagles, their backpacks aren't as
heavy as the boys calculated. Just a small mistake with a decimal would
mean a terribly heavy backpack for an eagle! Try This! As the boys in New York point out, this is what people--including the scientists--are concerned about. Scientists do not want their research to interfere with the life of the eagle. This is for humanitarian reasons, but also because they don't want their research to be affected. The scientists want to learn about NORMAL eagle behavior. How many ways can you imagine that the backpack might cause ABNORMAL behavior? The scientists must always have this in mind when they design their research--and also when they interpret the results.
