Journey North Mystery Class: A study of sunlight and the seasons

Can You Find the Mystery Class Sites? In this global game of hide-and-seek, students search to uncover the secret locations of ten "mystery" sites hiding around the earth. To guide the investigation, they track changes in day length at the mystery sites and at their hometown, and use other "clues" along the way. As they take this inspiring journey, students unlock the essential questions behind the reasons for seasons and the dramatic changes in day length that result. Mystery Class starts in early February but you can get ready now.(See: "Countdown to Mystery Class: Three Months to Go!")
