I use this after students have learned the basics about weathering, erosion, and deposition. My on-level or special needs students use their notes about WED to help them with the follow-up questions to the activity at each station.
Students travel in groups around the room to complete each activity. Warning: as with most hands-on activities, it can get a little messy, but it's well worth it as students remember this activity and you can reference it as you go forward through the geology content throughout the year.
At first, students simply love the stations because they are hands-on and require some group work skills, but I love the activity because the questions require them to apply what they've learned about WED. When we go over the stations together as a class, it's obvious they have gained a deeper understanding of weathering, erosion, and deposition by seeing these processes "in action" in the classroom.
