Electricity: 3-D Model

How Things Work

Ji Kim

Assignment: Create a 3-D model of the topic you have chosen. It may be made out of popsicle sticks, paper mache, Lego, software such as SketchUp etc. Label the parts and provide a written explanation of the following questions. Using at least three educational sources, research your topic and answer the following questions.

Topic : Tidal Barrage

• What problem is your topic trying to solve?

Making the electricity by using the tidal power. The tidal energy is the renewal energy, so we can use everytime. The tide is always happening in the sea, so it is useful.

• Form and Function: What are its main parts and what do the parts do? How does it use or generate electricity? How do electrons move through it?

1) Turbine – moved by the water. This moving sends an energy to the electric power station.

2) Tidal barrage – it is a wall that blocks the water.

3) Generator – it changes the tidal power that from the turbine to the electricity.

4) Electricity power station – sends the electricity to the city.

When the water comes to the turbine, it spins, so the power from the turbine is changed to the electricity by the generator. The electricity power station sends the electricity to the city.

• What are the social implications? (How might people be affected?) Consider less developed countries and locations with different climates or geography.

cons)

1. If the countries do not have the sea, they cannot use it because it uses the tidal energy that only works in the sea.
2. It can ruin someone’s place because the sea can be someone’s place. It takes a long time to make.

pros)

1. If the countries have the sea, it makes useful power.
2. It makes new jobs because someone has to control it.

• What are the environmental implications? (How does it affects the natural world?)

pros)

1. It blocks the flood or big waves from the sea.
2. It is renewal energy, so it is not risky to the earth.
3. The around of place that makes the tidal barrage becomes a better place because they can provide the electricity near cities, so near cities will be developed.

cons)

1. It damages the natural ecosystem because it blocks fish’s routes.
2. It causes the water pollution because it forces to block the water’s moving.
3. It needs a lot of money to make.

• Are there ethical implications? If so, what are they? (What is morally right or wrong?)
• Yes, there are. It is not ethical to nature. It destroys people’s habitats and nature habitats. This is morally wrong. However, It is ethical to nature other way because it uses the renewal energy, so it saves the earth.
• What are its weaknesses?
• Only able to use at the sea that has a big different tide. It needs a long time to build.
• Given these weaknesses, is it a satisfactory solution to the problem it is trying to solve?
• No, it is not.
