This unit is divided into 3 Arcs. Arc 1 answers the essential question, “What is weather and what factors influence

the weather?” The learning activities included in this arc guide students to use observation skills in order to

describe, explain, and predict weather patterns. Students will learn that the sun’s energy is the driving force of our

weather. They will complete activities to learn about wind, clouds, precipitation, temperature, and the role the

water cycle plays in our weather.

In Arc 2, students examine the essential question, “How does the ocean affect our weather?” Students will

complete activities to help them describe and explain the gulf stream, El Nino, La Nina, Sea and Land Breezes as

well as hurricanes.

Arc 3 allows students to investigate the essential question, “How does weather affect our lives?” Students will

complete activities to help them explain why our choices are based on the weather, as well as the impact that

climate change as on ecosystems. During the culminating activity in Arc 3, students research how to prepare for

extreme weather. Students have several opportunities to use their observations skills while working on their

nature journal
