Weathering and Erosion

Investigation 1: Chemical and Physical Weathering

In Investigation One, you will explore the chemical and physical weathering of rocks and minerals. During this Investigation, you will:

  1. Attempt to physically weather marble chips.
  2. Chemically weather marble chips with hydrochloric acid.
  3. Simulate continued chemical weathering on marble by submerging calcium carbonate into hydrochloric acid.

Investigation 2: Factors of Erosion

In Investigation Two, you will analyze several factors that cause erosion including wind, water, slope, and obstacles. During this Investigation, you will:

  1. Model the effects of erosion on two different slopes.
  2. Observe the effects of erosion when obstacles and vegetation are present.

Investigation 3: Components of Soil

In Investigation three, you will study the various components of soil that result from weathering and erosion. During this Investigation, you will:

  1. Compare and contrast the appearance of the components of soil such as sand, gravel, and organic material.
  2. Use a sieve to separate each component of soil to identify the size and amount of each component in a soil sample.
