First, check out this BrainPOP video on water erosion for a general definition: Erosion
Then, explore this National Geographic article on erosion for more detailed information as well as some really cool pictures that show the effects of erosion all over the world: National Geographic Erosion
Still not sure about erosion? Watch this HowStuffWorks video for more information/review: Power of Water Erosion

If time permits, work with your classmates and your teacher to design a stream erosion investigation. Here are a few ways to do this:
Erosion Streaming Tables (Do all of Day 1 including Class Demonstration, Outside Activity, and Closing Discussion, also do Day 2 Follow Up/Extension Activity)
You have seen the effects of stream erosion, but what about wave erosion? How does each wave and the wind contribute to the erosion process? Explore the following website's interactive 3-D wave simulator to see this in action: Wave Simulator
By now, you should be able to answer the following questions: 1. What is water erosion? 2. What are the different types of water erosion? 3. How does water erosion occur? 4. What are the effects of water erosion in the short term? Long term?
Turn and talk to your partner(s) about each of these questions and then stop and jot your thoughts about each question in your science journal. If you are unsure of how to answer any question, review the resources above to clarify your understanding. When you are done, please see your teacher with your journal before continuing on to part 2 of your journey.
