You are an archaeologist on a dig in a back garden. Lots of interesting objects have been found, but there are also some modern-day things that people have left lying around.
It's your job to tell the Site Supervisor exactly where you found each object, and to decide how old it is. Things of the same age are found together in the same layer, with the older layers at the bottom and the newer ones on top.
To make your report, click on each object and drag it from the bottom
of the screen to a box in the layer of the correct date. How many can
you get right?
