Landslide: A Natural Hazard Andy Wilson Third Grade Science New Market Elementary School z Landslide: A Natural Hazard

z Today’s Objectives: Explain how a landslide can affect humans and the environment. Create a retaining wall that is strong enough to keep rocks and soil from falling onto a makeshift road.

z Essential Questions: How does a landslide affect humans and the environment? How can a landslide be prevented? What causes a landslide to occur?

Let’s create a KWL Chart! z z Let’s create a KWL Chart!

z What is a landslide? A landslide is the sliding down of a mass of earth or rock from a mountain or cliff. Mudslide, rockslide, or avalanche

z Types of Landslides Rockslide Mudslide Avalanche

What can cause a landslide to occur? z What can cause a landslide to occur? Earthquake Explosion/Volcano Heavy Rain Powerful Noise (Screaming/Yelling)

Today’s Objectives: Explain how a landslide can affect humans and the environment. Create a retaining wall that is strong enough to keep rocks and soil from falling onto a makeshift road.

Essential Questions: How does a landslide affect humans and the environment? How can a landslide be prevented? What causes a landslide to occur?

Scenario Wilsonville citizens and visitors are concerned about a rockslide that could occur on Wilson Hollow Road. This road is steep and narrow and goes up into the mountains. The mayor of Wilsonville has hired you and your team to create a plan to build a retaining wall at the base of the hillside that can help protect the road and vehicles that drive through each day from a rockslide. Your retaining wall must be made from the materials provided and be able to hold up against the forces of a rockslide.

Materials and Cost: Overall Budget $50.00 Cardboard $5.00 Each (1 Piece per group) Spray Foam $20.00 Per Can (1 Can per group) Wooden Dowel $5.00 Each (Limit 3 per group) Masking Tape $10.00 Per Roll (Limit 1 per group)

Today’s Objectives: Explain how a landslide can affect humans and the environment. Create a retaining wall that is strong enough to keep rocks and soil from falling onto a makeshift road.
