Math 8 – Students did their Barbie Bungee Jump today. A few groups got really close! The big difference between a good jump and not-so-good jump was that many students included the lenght of barbie in their equivalent ratio. So they not only multiplied the stretched elastic when scaling the distance but Barbie’s body length was multiplied too. This problem is avoided if graphing is used – Barbie becomes the y-intercept. We may come back to this after linear relations.
