Students develop an understanding of covalent and intermolecular forces. They are also introduced to ionic bonds, bond length, bond energy, dipole moment, geometry, and Lewis Dot Structure. Students prepare a lecture about bonding...

Students compare cell structure to the structure of a city. In this cell structure lesson, students investigate differences and similarities between cell structure and city structure. Students create a 3-dimensional, edible model of a cell.

Sixth graders explore Lewis and Clark's expeditions. For this Lewis and Clark lesson, 6th graders view the routes they took and discuss how the territory has changed. Students make a timeline of their journey. Students research online...

Fourth graders investigate two types of water vessels that were used by Lewis and Clark during the exploration of the Louisiana Territory. They interpret data to determine which vessel was more efficient.

Third graders examine the significance of the Louisiana Purchase and the journey of Lewis and Clark, and discuss "needs" versus "wants". They listen to a story, plan for a journey like Lewis and Clark, create a list of supplies, and...

Young scholars explore the significance of the Louisiana Purchase and the journey of Lewis and Clark's Corps of Discovery. They read to explain a new topic and write to inform readers of the historic events they explored.

Second graders describe the impact of certain figures in United States history, including Meriwether Lewis and William Clark. They describe experiences of early American explorers and compose narratives from the perspectives of others.

Learners examine the challenges that faced the United States as a new nation, especially those related to exploration, expansion, and international affairs. They study the chronology of events related to the expedition of Lewis and Clark.

Fifth graders explore places visited by Lewis and Clark. In this geographical concepts lesson, 5th graders plot places on a map and put events in chronological order. Students find locations on a map using longitude and latitude....
