Today was the big day! Students finished up graphing and analyzing their data and making their bungee strings. Then we went out for our first run. Most groups were able to go and I will say, I was very pleased that we had no Barbie deaths!!! :) You can watch the video of the jumps below.

Today, the students were able to finish any trial drops to collect data and then were asked to analyze it. They graphed the data points, drew a line of best fit, write an equation for the line and will then use that to predict how many rubber bands will be needed for their doll to drop from a certain height in a way that it gets as close to the ground as possible. Students were also able to use the online graphing calculator on Desmos.com to make a table of their data and generate the actual line of best fit to see how close their line was that they drew. Desmos is a great free online too for teachers and students (and maybe even parents) to graph functions, plot tables of data, evaluate equations, explore transformations, and much more! This week we're doing our Barbie Bungee project! We started off by looking at a couple videos of the world's tallest bungee jump and talking about what makes a bungee jump the most fun. The students decided that the person should drop as close to the ground as possible without touching it. Then, I gave each group a Barbie and some rubber bands to start collecting data about how far their Barbie drops compared to how many rubber bands were used. Eventually, the students will have to create a full sized Barbie Bungee cord for an undisclosed location. We plan on having the actual jump on Thursday. It'll be exciting to see which group gets their Barbie closest to the ground without hitting it! |
