We read about canyons the other day and then decided to try to make our own. First we made a tiny ditch in some sand (old sand in the driveway that Rob dumped out from one of the sandboxes). We then ran some water down the ditches to make little rivers. Last we poured a gallon pitcher fast into the "river" and flooded it leaving behind a canyon formed from a HUGE flood. I wish I would have taken a picture of our little river. Below is the picture of our canyon we made. After that they did some sand play and experiments without me.
