Olivia taking careful observation notes
Children observed that a slow pour of 100 ml of water had less erosion than a quick dump of 100ml of water.
Children noticed that the water eroded the sand and made valleys down the middle or washed out everything.
The next task is to use our understanding of how water erodes sand to protect some houses from falling down the hill--stay tuned!
The erosioin models are ready for the water!
