Scribe post #3 Bl.6 by Fernando Maksoud

Today's schedule was the following:
  1.  Scribe Roll
  2. Energy Q&A #1
  3. Energy Collaboration: What are good and bad points of generating electricity? - nuclear, wind, solar, biomass, hydro
  4. Investigate  what materials can electricity flow through

Scribe Roll

1. We decided that I would be the class scribe.  

 Energy Q&A #1

2.The Q&A #1 is a document that reviews questions and answers for electricity. If a student has doubts he/she should consult the document.

 Energy Collaboration: What are good and bad points of generating electricity? - nuclear, wind, solar, biomass, hydro

3. First the groups carefully read the in formation in the text books. Each group consist of four students. One of the students wrote the facts on the computer while the others read and told the information to the one in the computer. 

Each group read about a different kinds of energy. They read about Sola, r, Nuclear, Geothermal, Hydroelectric, and Wind.

The wind group, Thiago, Max, Will, and Be, learned that: 
- It's very expensive
- It generates little electricity
- Doesn't generate electricity when it doesn't have any wind
-The large blades of the wind turbines can be mistaken for planes or other weather patterns

The Nuclear group, Tomate, Adam, Isa, and Mari, learned that: 
1. You can make weapons with nuclear power.
2. Fukushima was a meltdown.
3. There are over 400 nuclear power reactors in use around the world.
4. It can create nuclear waste which is hard to dispose of safely.
5. 30 different nuclear power reactors around the world.
The Solar group, Daniel, Valeria, Dominic, and Andre, learned that:
Some of the solar panels are portable. Solar cells / photovoltaic cells are used to generate electricity in spacecraft since the start of space age. Some panels can work at night because it stores the energy from the day. Solar cells may eventually lead to power plants that can produce millions of watts of electrical power. The largest power plant in the world is found in the Mojave Desert, USA. Most people put a large amount of solar panels on their roofs.

The Hydroelectric group, Gabi, Caroline, Gorge, andAlthea, learned that: 
1. In 2006, hydroelectric power powered 20% of the world's electricity. 
2. Hydroelectricity generates electricity by harnessing the gravitational force of falling water.
3. The most common type of watermill grinds grains into flour.
4. Tidal power is another form of hydropower, it uses the energy of tides to create electricity.
5. It is a renewable energy but the building of the large facilities needed to make it can have negative effects on the environment.

6. Hydropower uses the energy of moving water for a variety of useful applications. 

The Geothermal group, Lucas L, Heitor, Zora, and Angelica, learned that: 
1. The world's largest geothermal power plant in California, which makes electrical energy for 1.7 million households. 
2. The word geothermal comes from Greek words meaning earth (geo). 
3. The power plant in New Zealand has operated since the 1950's. 
4. Geothermal heating applications include industrial uses, heat pumps, space heating and bathing in hot springs. 
5. The oldest spa known fed from a hot spring is believed to be a stone pool 6. 30% of the electricity in the Phillipines is geothermal energy, and in the US it's less than 1% 

                 Investigate what materials can electricity flow through

4. At the end we talked about last classes lab, what can electricity flow through.
