Which way should they turn?

Abigail and her friends are in the middle of a Monday afternoon group project when Mr. C tells them it's time to jump back to the past. They're super-excited, even though this time things are more complicated than ever!

The kids have to convince Sacagawea not to give up on her dream. But they don't know what Sacagawea's dream is! Sure, they know that explorers Lewis and Clark mapped a route leading out West...but what does that have to do with the teenage Native American?

Can Abigail and her group find Sacagawea, figure out what her dream is, and convince her to stick with it -- all in just two hours?
