Woah! Slacker poster! Perfect Man and Hot Dogs

Standard

Has it really been 2 weeks since I posted? Oddly, in my head I posted the results from the great hot Dog experiment and the Perfect Man project (which I stole unbashedly).
First, the Perfect Man. yes, i know it’s a middle school project, so it was well within the range of challenge for my low performing students. I solicited contestants for the “Perfect Man.” I am so lucky to work with some great guys who were willing to be measured, as long as all the measurements were along the outer sides of the body. It was enlightening for some of our English teachers to see the measurement skills of our students – they are getting an inkling of the skills our students need to master at 9th and 11th grade in “math” class.
Then we calculated ratios of the “perfect man” and of the “measured man.” Finally, the students calculated the percent difference, and were able to create posters for “their guy.” We put the posters outside in the hallway, and we’ve had several visitors. Now I have created an essay contest for the “Perfect Man”- persuade me that the person you pick is indeed perfect. I have a give-away TI84 calculator as a prize.
Then last week, we completed the Hot Dog experiment. I bought 100 hot dogs and 50 buns. I found we only had 6 thermometers in the entire school (it was school of Health, Science and Technology – now the school of Health Science, apparently we have no technology). So we had groups measuring the temperature drop over time of a hot dog in air and in a bun. I did this at home, and I had a good difference between air and in the bun, but we did not see this at school.
We did get nice exponential drops in temperature – clearly not linear. And most kids got the excel modeling done in 2 days instead of a week. Clearly some skills are improving. Hurrah!
Too many hot dogs. I blame the ‘flu, as having 25% of the students gone meant there were too many hot dogs, even for teenagers.
