4th Grade Science Unit 5

Big Idea:

The effects of nature are slowly changing Earth’s surface.

Student Expectations:

Focus TEKS

4.7(B) [Supporting] Observe and identify slow changes to Earth’s surface caused by weathering, erosion, and deposition from water, wind, and ice

Ongoing TEKS

4.1(A) [Tools to Know] Demonstrate safe practices and the use of safety equipment as described in Texas Education Agency-approved safety standards during classroom and outdoor investigations using safety equipment, including safety goggles or chemical splash goggles, as appropriate, and gloves, as appropriate.

4.2(A) [Tools to Know] Plan and implement descriptive investigations, including asking well-defined questions, making inferences, and selecting and using appropriate equipment or technology to answer his/her questions

4.2(B) [Ways to Show] Collect and record data by observing and measuring, using the metric system, and using descriptive words and numerals such as labeled drawings, writing, and concept maps

4.2(F) [Ways to Show] Communicate valid oral and written results supported by data

4.3(A) [Ways to Show] Analyze, evaluate, and critique scientific explanations by using evidence, logical reasoning, and experimental and observational testing

4.3(B) [Ways to Show] Represent the natural world using models such as the water cycle and stream tables, and identify their limitations, including accuracy and size

4.4(A) [Tools to Know] Collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, spring scales, balances, graduated cylinders, beakers, hot plates, meter sticks, magnets, collecting nets, and notebooks; timing devices; and materials to support observations of habitats of organisms such as terrariums and aquariums

Student Learning Targets:

• I will differentiate between weathering, erosion and deposition.
• I will identify different causes of weathering, erosion and deposition.
• I will write about the changes to Earth’s surface from weathering, erosion and deposition.

Essential Questions:

• How do weathering and erosion shape Earth’s surface?
