Now that we've figured out about where our drinking water comes from, and how the lake refills, we're still curious about all this water and where it comes from. We recognized that the lake may refill with water from precipitation and from other bodies of water that flow into it because they're at a higher elevation, but is there any other way? How does a river even start, especially if that's the source for the lake?
We watched a series of videos to see how snow melts and becomes liquid water, but we weren't really sure that the water was still there. So we're doing a series of investigations not only of ice melting, but of water freezing back to ice. We're specifically looking at the water's mass, because if the mass stays the same, then we'll know the quantity of water must be the same even though it may look different. Some students are throwing around ideas of evaporation too, and that this helps keep the water "moving" as someone said. It's still not helping answer the questions we have about our concerns with our water making it to the ocean...
