I think I have been reading about the famous Barbie Bungee for about 2 years now. I don't know what I was afraid of - lack of time, mostly. But, you know, just make time.
I did Barbie Bungee today in two Accelerated Algebra 2 classes. It was a hit. They had already learned how to make scatterplots and determine lines of best fit. Then they made their predictions. After the activity, I used the Barbie data to introduce the correlation coefficient and how to do linear regression on the calculator.
Here is all my stuff set up for Barbie:
Another note, I had a skirt on today to wear, but realized I would be standing up on a table - so don't wear a skirt. I realized this in time at home to change.
Here are some kids doing it:
It was awesome! I got to finally have fun with my students in a way I got to know them.
I highly recommend you try it.
