# Barbie Bungees Again

8th grade and High School Statistics / Algebra

**Description**

Students will collect and analyze data to help them predict the longest bungee cord that Barbie can use safely.

### Hook

The teacher should find a video showing a real bungee jump and lead a discussion on what makes a good bungee jump. After this discussion, present the scenario about Barbie and her bungee jump.

Barbie is interested in going bungee jumping. Since she is a thrill seeker, she would like to have the longest jump possible, without hitting the ground. Help Barbie decide how long the bungee cord must be to give her the most fun without getting injured.

### Lessons
