Data exploration and getting new insights from data is more important today than ever before. Exploring data is an important part of data science and can be a fruitful topic in middle school. New insights can be gained from rich data, but this requires a good data basis. Therefore, we present multivariate and rich data of over 1200 young people who answered an online survey on more than 150 questions. Several examples of possible data explorations of this data are presented. A short glimpse is given to a corresponding teaching unit for grade 8-10. With a suitable data science tool, students can handle and analyze such rich data. Students' presentations at the end of the teaching unit show the insights students get from the data but also, show challenges when exploring multivariate data.
