For three days, we collected data, made our equation, and did the final jump for the Algebra project "Bungee Barbie". Before we started, we learned about slope and the line of best fit so we could use that knowledge in the project. We each got one or two partners to work with. Our goal was to get Barbie the closest to the floor without her head touching the floor. On our first day, we did data collection by recording how far barbie fell with a certain number of rubber bands. We created a function table showing the number of rubber bands (x) and the number of inches Barbie fell (y), then graphed those points on a coordinate plane. On day two, we made our equation from the data from yesterday's data collection. We found the slope and drew a line of best fit, then we checked our work by inputting the data on a website that showed us the equation. On the final day, we did the big jump! Ms. Bad told us the height that Barbie would drop from on the day of (76.5 inches), so we had to use our equation to find out how many rubber bands we would need for Barbie to be safe and have a fun ride. After the big jump, we found the average of our three attempts and we found out who had the lowest average. The winning team was Marin and Derek with an average distance of the floor of 0.13 inches! Check out the photos of our project below! Which part of the project was your favorite?
