Science - 5th Grade
Standard 2 Objective 1
The purpose of this activity is to teach writing in a science context using the text structure of compare and contrast.
It is assumed that Introducing Text Structures in Science has already been taught using descriptive text structure examples. This lesson is intended to be a model lesson and is not expected to be the only occasion where students write cause and effect texts in science. The principles taught in this lesson may be adapted for use in any of the Science Core Curriculum Objectives where cause and effect is emphasized. Look for the phrase explain the reasons in the Science Core Curriculum.
This activity is intended to mesh with the activities about weathering and erosion in Standard II. Students will write about the causes and effects of a simple Earth process. The geologic processes of Earth are the result of forces within Earth and on the surface of Earth. The cause and effect structure is ideal to explain about these processes. This activity should be used after students have had several experiences learning about weathering and erosion. For information about weathering and erosion, consult the Teacher Resource Book.
1. Use Science Process and Thinking Skills
3. Understand Science Concepts and Principles
4. Communicate Effectively Using Science Language and Reasoning
Invitation to Learn
Show a picture of a rock formation that shows evidence of erosion. If possible, show a poster from one of Utah’s national parks such as Arches, Bryce, Capital Reef, Canyonland, or Zion National Park. Discuss the processes that made the formation as it appears today.
