Challenge Question #1Roberta Prescott (rprescott@dusd.k12.ca.us)Thu, 10 Sep 1998 16:37:27 -0000
calculated the arrival date of the majority of Monarch Butterflies to be October 16, 1998. To come to our arrival date we first looked up various facts in the encyclopedias, nature books and geography books. We discovered that Monarch Butterflies travel approximately 20 mph. We located Mochoacan, Mexico and using a ruler measured the distance from Santa Cruz, California to the middle of Mochoachan. We chose Santa Cruz, California since there is a state park there that is know for its clusters of Monarch Butterflies. They are the thickest there in September-October and we voted and decided that they would leave that spot on October 7th. We measure the distance to about 2000 miles and thought that they might travel 12 hours a day. By multiplying and then dividing we found that it would take 8.5 days to get there. We had fun and learned a lot whether our estimate is the correct one or not. Thank you, Roberta Prescott
