How do Waves Impact Beaches? Exogenic Processes At this lab station, you will investigate how waves impact beaches. To model a beach, you will create a patch of sand on one end of a large pan and then slosh water back and forth inside the pan to model waves. Materials: • Large pan • Water • Sand (enough to make a "beach" at one end of the pan) Procedure: 1. Using dry sand, make a "beach" at one end of the pan. Pack the sand down, smooth it out, and then record your observations of what your beach looks like. 2. Make sure there is water in the pan and then slowly slosh the water back and forth to model waves washing up on the shore of your beach. 3. Watch what happens to the beach the longer you do this. 4. Record your observations after you've experimented like this for about five (5) minutes. 5. Write down your thoughts about how waves alter beaches. Make a prediction about what would happen over a long time period if the waves continued to do this to the beach. 6. Record whether you think this exploration demonstrated chemical weathering, mechanical weathering, or erosion. 7. When you've finished, scoop out any wet sand and clean up the station. 07 Activity 1 *Property of STI Page 5 of 5

How do Waves Impact Beaches?
Exogenic Processes
At this lab station, you will investigate how waves impact beaches. To model a beach, you will create
a patch of sand on one end of a large pan and then slosh water back and forth inside the pan to model
waves.
Materials:
• Large pan
• Water
Sand (enough to make a "beach" at one end of the pan)
Procedure:
1. Using dry sand, make a "beach" at one end of the pan. Pack the sand down, smooth it out, and
then record your observations of what your beach looks like.
2. Make sure there is water in the pan and then slowly slosh the water back and forth to model
waves washing up on the shore of your beach.
3. Watch what happens to the beach the longer you do this.
4. Record your observations after you've experimented like this for about five (5) minutes.
5. Write down your thoughts about how waves alter beaches. Make a prediction about what would
happen over a long time period if the waves continued to do this to the beach.
6. Record whether you think this exploration demonstrated chemical weathering, mechanical
weathering, or erosion.
7. When you've finished, scoop out any wet sand and clean up the station.
