Day 1
Objectives
- Students will define weathering.
- Students will differentiate between chemical and physical weathering.
Students will list products of weathering.
- Students will differentiate between chemical and physical weathering.
Students will list products of weathering.
Materials
- Power Point
- Plaster and Ice Experiment- plaster of paris, water, a small balloon, two empty pint milk cartons (bottom halves only), a freezer
- A Sour Trick Experiment: lemon juice, vinegar, medicine droppers, two pieces each of limestone, calcite, chalk, and quartz

Events of Instruction
- Test prior knowledge. Introduce concept of weathering, erosion, and deposition. Explain that weathering is the first phase of this process. (5 min)
- Expand on weathering in brief. Highlight areas for students to take notes in notebook. (5-10 min)
- Set up first part of the Plaster and Ice Experiment in front of students. Explain that this will show physical weathering through freezing water. (experiment requires an overnight freeze to be continued in next session) (5-10 min)
- Chemical Weathering Station- Have materials and instructions set up into stations. Split students up into groups of about four. Conduct A Sour Trick experiment. Students will record hypothesis and conclusions in notebook. (15 min- 20 min)
- Discuss as a class results. (5-10 min)

Ideas for Differentiation
- Provide handouts for notes for students that may need them.
- Split students based on academic level and adjust instructions and level of exploration based on student need.
