Time capsules are so much fun! The kids get a kick out of doing this project each year and it is a great get to know you activity as well. I think it helps students think about what they want to accomplish this year and it gives you a little information about them.
In my own classroom I have done this project every year for the last 9 years. This file includes a printable download of the time capsule sheet. After students finish filling it out, I place each one in a special time capsule container that is visible all year. Then on the last day of school, we open it up and compare how they have all changed and discuss if goals were met.
This project is a super reminder for students about how much they grow throughout the year.
