What's Going on in the Lab? Bungee Jumps!

Oh my goodness y'all!! This post is jam-packed with deliciousness all about our latest STEM Adventure!
All About Bungee Jumping!
STEM Challenge:Can you find the exact number of bungee cords Barbie needs to have a safe jump? Experiment and find out- then design the perfect device!

Let me just tell you that when this began to come together I was so excited! I knew my fifth graders would LOVE this! And they did!

First, you have to watch this. I just learned how to make movies and I am having a blast producing things! You should see my cat movies.....
Okay, that was pretty cool, I know!
Here's the background of this challenge!

This idea came from a student! She mentioned bungee jumping one day as we were talking about our fourth graders recent visit to the Space and Rocket Center. It seems they have a bungee jumping contraption there that many of our students tried. (Not a real tower jump, more like a trampoline.) Anyway, I started thinking about jumping or dropping something. My first thought was to use eggs..... then I thought about a Barbie doll!

First off, I needed Barbies!
Off to the Dollar Tree. I came home with a bag full of Barbies, added weights to them to make them a little heavier and then attached our "bungee cords".

Okay, what to do with them? My students love to experiment so I added some testing to this.
The kids tested Barbie with an increasing number of cords.

They filled out a data table with the jump results and averaged the data for each test level.
Then, are you ready for this??
We used the data to plot points on a line graph and did some fabulous math to extend our graph lines and predict how many cords would be needed to drop Barbie from a much higher spot.

After deciding the number of cords, kids got the dolls ready and I stood on a stool to drop her from our doorway.
The arrows in the photos below are pointing to Barbie. It's hard to catch a Barbie in a still shot- especially when I had students taking the photos!

This was such fun and SO FULL OF MATH!
This challenge is now number three on our list of favorites- right behind Pancakes and Roller Coasters!

  1. Hi! This looks like so much fun! What an adventurous Barbie. I'm your newest follower but I can't figure out the picture thing so I am just a blank head :)

  2. Thanks for stopping by! I think the photo that appears needs to be your photo that is loaded into your Google account. Try going to your Google+ page or your gmail account and changing the picture!

  3. For your "cords", did you use rubberbands or yarn? I know you used bands around the feet, but what did hang from the wall and doorway?

    1. Hi Gianna! It's all rubber bands! You can read more about it at my TpT store!
