I wanted to send my seniors off with something fun that would leave them with some lasting memories. I stumbled onto the idea of creating time capsules with water bottles. Some searching showed me some images, and I found some TPT resources that seemed more appropriate for younger students. So, I set out to make my own version.
The "white sheet" was where students could write about themselves; their favorites, and predictions for their life. I copied one for each student. If you want to spread the project over several days you could give students the "white sheet" as a warmup the day before or for homework.
My students customized their caps with pens and pencils. Next time I will encourage more of them to use colors and markers. Very important: Use a hole punch to add a hole to the grad cap somewhere. I did this after my students decorated, so that I could place the hole where it would not interfere with their design. Next time, I'll punch two connected holes, so that it will be a little easier to fit the ribbon through. This year I had to use some white string to create a loop so that I could tie the grad caps on the bottles.
