Activity Based
Why would paper be a poor choice for a real life dam? (One reason)
- Lack of structural strength
- Permeable
- Lack of durability
What two words describe a force?
Push / Pull
Provide one example of a suitable material to construct a dam with
- Concrete
- Stone/Masonry
- Steel
What's the difference between a retaining wall and a dam?
A retaining wall focuses on soil retention while dams are intended for water management/control
Provide the name of one real life example of a dam
Hoover Dam
When the dam began to fail, why did the marbles deform the bottom section of the cardboard first?
Pressure increases with depth
What force is responsible for keeping us grounded on Earth?
Gravity
What are the three types of dams?
1. Buttress
2. Arch
3. Embankment
What shape are retaining walls?
L-Shape
What does the term "hydroelectric" mean?
The generation of electricity using the flow of water
What benefits are there of using an arch shaped dam? (One example)
- Structural strength - the curved design efficiently distributes the force of water
- Uses less material (more efficient)
If you slide a book across the table, what force will act on the book in the opposite direction?
Friction
What are all the forces that act on dams?
Gravity, pressure
How does a retaining wall's shape prevent it from falling over?
The soil is able to provide support to the retaining wall
What's a negative environmental impact of constructing a dam? (One example)
- CO2 emissions
- Disrupts wildlife
- Erosion of surrounding land
