Why do Rivers Flow?

This week we conducted an investigation to discover why rivers flow.  The class hypothesized that they flowed because the wind pushed them, the animals swimming underneath made them flow or other rivers pushed them. 

After our investigation, they learned that rivers flow because they begin at the tops of mountains and hills and flow down to the oceans.

Tomorrow we are going to look at the rivers in Idaho.  Feel free to do some research about Idaho rivers and which ocean they flow into at home so your second grader has even more to share tomorrow.

Here are some pictures of our models.  Ask you second grader to tell you about it.
