Choose a box and lid from the supply table.
Move to work tables and securely tape lid upside down to the bottom of the box;
Line the inside of box lid with aluminum foil. Glue the foil in place to create a tight fit.
Decorate the outside of the box and lid to create a building: house; apartment building; grocery store; fire/police station; community center; church; etc.
Bring decorated box to the supply table for potting soil.* Spread the soil evenly on top of the aluminum foil.
Sprinkle grass seed from one Dixie cup onto roof soil. Use a fork to “hoe” to evenly distribute the seeds in the soil.
Wash hands when done with the project (the soil contains fertilizer).
Grab an instruction sheet on How to Care for Your Green Roof (remember to water!).
*For easier transporting, potting soil and grass seed can also be placed in plastic bags so participants can finish them at home.
