Where did all the water that you poured into your cup go?
How does this model simulate what really happens to groundwater in the world? (How does water get underground? Where is water stored underground?)
Based on this experiment, what can happen to a drop of water after it falls on the ground?
Do you think humans use groundwater? If so, what do we use groundwater for?
How do humans get groundwater to the surface? Is this easy to do?
Do you think groundwater can move anywhere else? Where? How does it move?
How have your ideas about what happens to a drop of water changed since you started learning more about groundwater?
Some of the water stayed in the sand, and some of it dripped down to the bottom of the cup.
This simulates what really happens to water, because it shows how the water gets underground, and where it goes underground. I learned that some water soaks into the soil, and some of it goes down to bedrock.
When a drop of water falls on to the ground, it soaks into the ground, and eventually goes down to the bottom of the cup. So a drop of water in real ground would soak into the soil, and overtime make it's way to bedrock.
Humans use groundwater a lot, because it is one of the biggest sources of freshwater. We can only drink freshwater, so we use groundwater a lot.
Humans get ground water to the surface by drilling for it, or making wells. It isn't very easy to do because we have to use machines to get a lot of water. You could use a shovel, but you wouldn't get a lot of water.
I don't think it could move anywhere else, because the only other places it could move are left and right, and I don't think it would be able to move like that.
My ideas haven't changed much, but I learned about all the different layers of ground, and I didn't know that there were more then one type of soil in the ground. It changes my idea of how water travels through the ground a little bit, because some of the layers might stop water from getting to bedrock.
