  1. Wednesday, October 23, 2019 Objective: YWBAT describe how a rock’s total surface area affects the rate at which it weathers. Drill: Identify the independent variables in Problem 1 on the Weathering Lab. Homework Finish Rates of Weathering Lab

  2. Answer The type of rock

  3. Did you know…? Over time, the weathering of the copper on the Statue of Liberty created a thin layer of coppercarbonate called a patina. Although some people were worried that the changing color of the statue meant it was decaying, the patina actually protects the copper underneath from further corrosion.

  4. Today’s Activities Drill Rates of Weathering Lab Conclusion

  5. Weathering Lab - Analysis You must use your data to support your answers.

  6. Closure What is the dependent variable for the Weathering Lab?
