Barbie Bungee

Y = mx + b

Thrill her

Don’t

Kill her

???What & Why???

What

Why

Barbie will help us learn how math can be fun to use in the real world

She will be bungee jumping to teach us how to:

Collect data

Organize it

As a table

As a graph

Use mathematics to make predictions

We will learn to create and use our own line of best fit to develop a linear equation.

We will use our linear equation to predict Barbie’s Long Distance Big Drop.

We will use technology to assist us.

• Tie 3 rubber bands around Barbie’s ankles
• Drop Barbie from any platform.
• Record the distance she fell (Dis. Would be from the platform to the tip of her head)
• Repeat these steps to get an average for using three rubber bands.
• Add on 3 more rubber bands and repeat the first three steps
• Create a scatter plot representing (x)number of rubber bands & (y)distance of drop
• Choose a line of best fit
• Create an equation for our line of best fit
Information/Data

Table

Graph

Line of Best Fit

Final Step

Y = 4.756x – 5.608

Point of NO RETURN

Calculation

900.000 = 4.756x -5.608

+ 5.608 = +5.608

905.608 = 4.756x

4.756 4.756

190.41379 = x Or x ≈ 190

Our Equation:

Y = 4.756x – 5.608

Our Given Drop Distance:

900 inches

Our prediction was to use 185 rubber bands.

Drop Day

Does Barbie make it?

THE END

Unfortunatly, our prediction was wrong.

 Barbie did not survive the BIG DROP 

We apologize to those who will miss Barbie.

THANK YOU
