Earth Day Mayhem!

It's Earth Day and you and your class are really excited to help make your school and environment a better place. Your teacher arranged to have the groundskeeper, Mr. Reese Ikel leave the school's tool shed unlocked for your class on Earth Day. However, when you arrived to school on Earth Day, your teacher informed you that Mr. Ikel forgot to unlock the tool shed because he left for a 'Save the Earth Convention'. He did however send a website link in an e-mail to your teacher with clues for each lock so you and your class can unlock the school shed and help clean the environment!

It's up to you and your class to decode the clues and help save the earth this Earth Day!
