We are people who were given the power to act on behalf of other people. We were usually white men in charge of keeping peace between Native nations and other people.

We were chosen to explore the Louisiana Territory by President Jefferson. We lead a group of more than 40 men on the expedition across the west.

I am a person who explains the meaning of words or changes them from one language to another. A famous one of me, Sacajawea, helped Lewis and Clark communicate with Native groups on the expedition.

I am a document that more than doubled the size of the United States when land was purchased from France. Today's Nebraska was part of this land.

I am the body’s ability to resist disease American Indians hadn’t been near many germs that Europeans brought with them; many of them died because they didn’t have me (a natural protection) to help fight off many of the diseases.

I am a gift that was given to the Native Peoples from President Jefferson as a sign that they were “children of the new Great Father” and they would be protected if they remained peaceful.

I am a trip taken by a group of people to learn about the land, rivers, people, plants, and animals of a new place. I was led by Lewis and Clark.

I am an official agreement that is made between two or more groups where each group promises to do certain things.

I am the only woman that went with the group that Lewis and Clark led. I brought my young son along and served as an interpreter with the Native Peoples. I had great knowledge of the land and knew which plants were safe to eat.

We are people who taught other people about our religion. We thought our religion would make life better for the American Indians if it were taught to them.

I am freedom from the control of another person or group. The Revolutionary War was a war for me. The colonial leaders led others to start a new country and break away from England.
