CONSTRUCTIVE AND DESTRUCTIVE PROCESSES K – 5 Science Endorsement Unit Presentation

Goals of the Teaching Unit Concepts that will be targeted in this lesson plan The Earth is constantly changing. The Earth’s landforms were created by weathering and erosion. Essential Questions for this lesson plan: How do weathering and erosion affect the Earth’s landforms? Are weathering and erosion constructive or destructive?

Standards Addressed Georgia Performance Standards S5E1a Constructive Processes Identify surface features caused by constructive processes S5E1b Destructive Processes Identify and find examples of surface features caused by destructive processes.

Lessons to Develop Big Idea UNIT PRE-ASSESSMENT : Student will sort a list of processes found on the board into one of three categories: constructive, destructive, or both. ENGAGE : Pass out pictures of the Grand Canyon (several views per table, all same pics per table) and the Grand Canyon Student Page. Have students work in teams and discuss and answer the questions on the Grand Canyon Student page. EXPLORE : Use non-fiction text on the Grand Canyon to introduce the formation of the Grand Canyon. Then students will complete in groups the Wind and Water Checkpoint Labs A – D (From Picture Perfect Science Lessons). EXPLAIN : Students will make vocabulary connections using their lab results and the remainder of the non-fiction text. EXTEND : Students will sort pictures of other landforms into weathering or erosion using new knowledge from text and from labs.. Then students will work in groups to create a brochure on the Grand Canyon with focus on how weathering and erosion have impacted its development. EVALUATE : Students will create a brochure to demonstrate what they learned about weathering and erosion and how the concepts can be applied to the formation of the Grand Canyon

Addressing Misconceptions Misconceptions: Changes to the Earth’s surface only happen quickly Weathering and erosion are the same thing Rocks are here to stay Earth’s forces can only destroy Truths Changes to the Earth’s surface can happen fast or slow (addressed in non-fiction reading) Weathering and erosion are both processes that change the Earth’s surface, but weathering is the process of breaking rock into sediment while erosion is the process of carrying that sediment away (addressed in labs) Rocks are subject to weathering, destructive processes and the rock cycle (addressed in labs and non-fiction reading) Earth’s forces can be constructive, destructive, or both (addressed in reading, discussion, and later in unit)

Cross-Curricular Integration Literacy: Reading two non-fiction texts to support science standards and address text features of the books while introducing or using them in accessing information Technology: Students will create brochures on Microsoft Publisher Social Studies: showing the Grand Canyon’s surface feature changes over three decades; explain what decade means Math: folding sheet into thirds, discuss what thirds are while folding occurs, what things come in thirds

Unit Assessments Pre-assessment : the unit pre-assessment will be the Earth’s processes sort to determine where students are in the understanding of what constructive and destructive processes are. FA : New Vocabulary Words sheet will assess student’s pre and post knowledge of vocabulary. FA : Correcting or adding more detail to the questions originally asked on the Grand Canyon Student page. SA : Grand Canyon brochure will assess how students apply weathering and erosion to the formation of the Grand Canyon, as well as changes that may occur every day in the Grand Canyon as a result of weathering and erosion.
