Advance Preparation
• Prepare one beach model for each team’s beach/coastline.
1. Pour sand into the clear container, make it wet, and pack it on one end.
2. Ocean: Pour 500 mL of water on the side of the container with no sand.
3. Vegetation: Stick grass, twigs, or toothpicks into the sand and along the beach/coastline.
4. Buildings/development: Press domino pieces and small rocks into the sand and along the beach.
• Using the materials from the For the teacher section, prepare a beach model to demonstrate what happens to the coastline as a result of rapid sea-level rise (storm surge) and erosion by water and wind.
• See page 147 for model example.
Vocabulary
beach deposition weathering
coast erosion
coastline sediment
Materials

For the class
For each team
• foam cups, plates, or pieces
• cardstock
• fabric
• craft sticks
• plastic cups, plates, or pieces
• gravel
• yarn
• cotton balls
• rubber bands
• foam egg carton tops
• paper towels
• masking tape
• camera
• 1 shoe-box size clear plastic container
• 1/2 gallon of sand
• small rocks/gravel
• dominoes or small plastic building blocks, to simulate buildings
• 1 small container lid, to simulate waves
• grass, twigs, or toothpicks, to simulate beach vegetation
• 1 L water
• 1 ruler
• 1 timing device
• 2 sheets of graph paper
• 1 shoe-box size clear plastic container
• 1/2 gallon of sand
• small rocks/gravel
• dominoes or small plastic building blocks, to simulate buildings
• 1 small container lid, to simulate waves
• grass, twigs, or toothpicks, to simulate beach vegetation
• 1 L water
• one 500 mL beaker
• 1 ruler
• 1 timing device
Suggested Time Frame
• Ask, Imagine, and Plan: 1–2 hours; may be broken down over a few days
research (not more than 60 minutes) explore the materials (about 5 minutes) sketch and plan independently (about 10 minutes) reach team consensus on final design (about 10–15 minutes)
• Create, Test, and Improve: 45 minutes
• Evaluate: 3–5 minutes to present and test
The amount of time needed for this challenge may vary depending
on your students’ research skills and findings.
