Learning Goal 4: I can interpolate and extrapolate values in scatter plots with lines of best fit.(LR)
Interpolation: ___________________________________________________________ Extrapolation: ___________________________________________________________
Purpose
You are going to create a bungee line for Barbie that will give her the most thrilling, yet SAFE, fall from a height of 3 meters.
Procedures
1. Connect two rubber bands with a slipknot.
2. Then wrap one end repeatedly around Barbie's ankles. Be sure the rubber band is on tight enough not to fall off when she is being dropped.
3. Measure Barbie's height without rubber bands. Record this amount next to the zero rubber bands in the data chart on back side of this paper.
4. Next, drop her with one rubber band attached to her ankles. Hold the band tight at the top of the yardstick, and simply let Barbie drop from the head-down position. She won't swing; she will just lightly bounce.
5. Now it’s time to start adding more bands. Once again use a slipknot to connect a second band to the bungee line. (Remember the band wrapped around her ankles does not count in the length of the line.)
Lesson 1.5: Barbie Bungee Name: _______________
Do not worry about your problems with mathematics, I assure you mine are far greater. –Albert Einstein
7. Complete the data chart.
Number of
rubber bands head reaches (cm) Lowest point
0
(i.e. from ankles)
1 (i.e. original band)
2 (i.e. 1 more band)

8. On graph paper, graph the points from the data chart. Draw in the line of best fit. 9. Now consider the SAFETY issue vs. the THRILL issue:
If you put too many rubber bands on, her head will reach the floor, she will crack open her skull, and die. You will then be sued for negligence and will lose your business and owe her family millions of dollars that you don't have.
On the other hand, if you don’t put enough rubber bands, therefore you shorten the bungee line TOO MUCH, the ride may not be thrilling enough, and Barbie will pay her big bucks to your competitor. You will lose clients and your business will suffer.
10.So based on your line of best fit, your prediction for the number of rubber bands for the bungee line for Barbie jump from a height of 8.5 meters (850 cm) is ________________.
11. Now, you are ready to test out the jump using the number of rubber bands you wrote for #10. (You may not change this number once it’s written down or when you have seen other groups test their jumps!)
