Since January, our class has been participating in a global scavenger hunt called Journey North Mystery Class. Starting on January 28, every week we have been calculating the photoperiod (that’s the length of time between sunrise and sunset) in ten mystery locations around the world. This has given us a chance to practice calculating elapsed time. Here’s a video showing how we calculate elapsed time using a number line.
We started to see some patterns as the weeks progressed. Some locations’ photoperiods got longer from one week to the next, while others got shorter. We realized that if the photoperiods were getting longer the location must be in the Northern Hemisphere (like us), and if the photoperiods were getting shorter the location was in the Southern Hemisphere.
Three weeks ago we started getting interdisciplinary clues about the culture, geography and history of the Mystery Classes. We started doing some research to see if we could figure out where they are. Some of them were pretty challenging, but we think we are getting close to figuring them out!
We think the most challenging clues are the ones for Mystery Class 8. First we thought it was in Madagascar, then Australia, then we thought it might be in Indonesia. We still aren’t sure, but we are learning a lot as we do our research!
