Before beginning this experiment we suggest drawing/ taking photos of/ taking notes on the rubbish items you are burying. In this way your kids will be able to treat the experiment as a report - and later can compare their findings before and after.
As with a time capsule, the best option is to find a part of the garden where it’s okay to dig, and you will need a way to mark the spot - as this is shorter term than a time capsule (which can stay in the ground for 10 years or more!) a wooden sign in the ground should do the trick. Try to bury your rubbish about a foot deep. Be sure to use gloves and take care with spades when trying this one out.
After burying your rubbish items it’s time to wait! Usually 2-3 months is the perfect amount of time. Then, get your camera or your pencil and paper ready, get digging, and record your findings!
