How to Compose Your Message

Materials: 4x6 blank note card, pen, timer, camera, glue, postcard stamp 

Take your materials to your favorite nature spot.

1. Enjoy your spot, alone, for 20 minutes (tip: set a timer). If your phone is your timer, do not look at or use your    phone during these 20 minutes. This is a technology-free activity.

2. After 20 minutes, compose your message to the Earth (write, draw, dance, sing…) Let your heart speak. 

3. Photograph yourself in your location. Be creative!

4. Print your photo and glue it to the backside of your postcard.
