Earth's jet streams are rivers of moving air that steer weather. Researchers discovered that they are shifting toward the poles and moving weather patterns with them.

I.Files allow each student in a group to read about a specific, high-interest topic related to unit concepts. Groups then discuss several files to identify common details in order to answer a Key Question. In this I.File, students learn how jet boats push out water to move. This I.File is written at the highest of three reading levels.

Racetrack Playa in Death Valley got its name from long tracks left behind by rocks, some as big as boulders, that inexplicably move across the valley floor. This decades-old mystery was solved by scientists who caught the rocks in action. In other news, archerfish spit super accurate water jets to capture prey; rubber from dandelion roots will soon be used to make tires; and plants that hear the chewing of hungry caterpillars produce a chemical that keeps the herbivores from eating so much.

I.Files allow each student in a group to read about a specific, high-interest topic related to unit concepts. Groups then discuss several files to identify common details in order to answer a Key Question. In this I.File, students learn how chemistry is involved in rockets and fireworks. This I.File is written at the highest of three reading levels.

The Unit Resource List identifies all the current resources within the Clouds, Wind, and Storms unit. Use this list to plan which resources to use, to note printing or projecting, and to record other notes about each resource.

The NGSS Correlations Chart lists the key student resources within the unit, then identifies which of the Next Generation Science Standards each resource supports. The chart correlates to relevant Performance Expectations using NGSS codes, which are explained at the end of the document. Using a variety of resources will help develop student proficiency in the skills required for each Performance Expectation.

FOCUS books are reading opportunities that allow students to dig more deeply into the content presented in a science unit. This book discusses how auroras—the northern and southern lights—form and change. This book is written at the middle of three reading levels.
