Scribe Post #6 30/8/13 - 34/8/13

                                       








                                                                       
                                                 You could go to Quizzlet to study for the test.                                                                                       

                                    


             
Wind energy and solar energy are both renewable resources. But that does not mean there is infinite of those energy resources but still it can last much more than the other ones like petroleum and coal because we probably have the sun as a resource for 4,000,000,000 years and petroleum for probably 40 more years. The good thing is that is does not cause pollution or global warming.







Petroleum and coal are not renewable resources and they also cause pollution to the Earth's atmosphere. But the problem is that we use those resources for almost every thing and if there is no more of petroleum we had to find another way of transporting people by airplanes and by cruses and that would make people out of work or business.



 We were also trying to figure out if it affects the rocket's altitude that it travels if we pump it a different number of times.




We had to get a cylinder jar that has ml measurements







                               Then you pour water inside the rocket.

        Science Class Summarized into a Great Post!



First we went over what did last class and Fernando's (previous) blogpost. The Mr.pro told us what we were going to do this class:

Class agenda:



Form Answers:

After going over what we were going to do in class, we went over our form answers, the form about energy collaboration, from last class:




Unit 1 Test Study - Question and Answer - Quizlet:

We worked on some vocabulary words that are going to be on the test, on quizlet. If you want to play more, click here.




Here is a picture of everyone working on their vocab words:






Non-renewable resources and Renewable resources:

Mr.Pro told us what are the renewable resources and the un-renewable resources, here are some pictures:





What are our natural resources? How do we categorize them? What are problems with using them?

After that, we watched a few brainpop videos that explain our questions above; Renewable Resources and Un-Renewable Resources, Fossil Fuels:







         Investigation Time!        


How do pumps affect how high a water rocket goes? 
Here is the link to the document where all the instructions are: Link







Discussions start on who's going to be the observer, launcher, and meter stick holder:









Step 1:  Fill the rocket halfway through with water.




Steps 2 and 3: Position the rocket close to the ground, vertically. The Put two meter sticks on top of each other to measure.



Step 4:  Pump the rocket 6 times (to start with).


Step 5: Pull the trigger on the rocket and launch it vertically.


Step 6: Observe and estimate how high the rocket went up.

Steps 7 and 8: Do it over and over again going from 6 to 10 to 14 to 18 (etc.)



Finally, when the investigation is done, Mr.Pro gathers the class and takes notes, everybody collaborates.

















Thank you for reading!

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.

Renewable reasources. When will we run out of oil?

     What we did first was start studying for our quiz on September 11th. We are using quizlet. Quizlet is a site where you can study for tests and quizzes. This can be very helpful. The site includes games and flash cards to help toy study for quizzes and tests.Everyone had to play a game on the site and had to beat there previous record. We had used this site before to study for other tests and quizzes in other classes.
After, we watched a brainpop on natural resources, and a brainpop on what the problems are with using them.The main questions we were trying to answer was " What are our natural resources?" " How do we categorize them?" and " What are the problems with using them? After this we answered some questions on natural resources. We learned that oil is not a renewable resource, but it is efficient. Scientists predict we will run out of oil in before the end of the next century. And so there is a lot of research on renewable energy sources like wind,water,and sunlight.
After watching the brainpops, we started doing an investigation and took notes. We used a chart with various numbers while using a pump rocket. On the chart there were numbers. However many numbers there were on the chart you were to pump the pumper in order to fly your rocket. Then you had to right down the information in the chart in your task book. The reason there are meter sticks is because we want to know how many meters up it goes with each pump.
This is a video of Stephanie,Gigi, and Anika trying out the water rocket.

Scribe Post 3#

                              Scribe Roll
In the beginning of class we chose the next scribes for the rest of the year. Every scribe chose the next one. Below there is a picture of the scribe chart.


                           Energy Q&A #1
The energy Q&A is a resource of studying to the test. It is a big document that has a lot of energy related questions and answers so that people can study for the test.


     Expert Collaboration: Good and Bad Points of Generating Electricity
We will be divide the class into 4 groups. Our aims are:
  • To work together

         What Materials can Electricity Flow Through?
                                 
                           Conclusion and answers.

    What will electricity flow through?

    In the first part of class, we talked about what we were going to do in class. We talked about the burning of the potato chips and making qualitative observations. 

    Next, we talked about which things electricity would flow through. Here is the hypothesis: Electricity will flow through metals but not plastics. Next we predicted what would flow with C ( Conducts) or I (Insulates). Tons of them were (I) because they were plastic and some were (C) because they were metal or have to do with metal.


    Here is the experiment we did in class.  You need a conductor for the electricity (battery),  2 alligator clip wires ( to connect electricity) a battery holder ( for the electricity of the battery to be spread) and a ammeter ( to measure the current of the electricity. In the pan were many different materials including: Pencil, Pen, motor, pyrite, graphite, quartz, bar magnet, wire with copper exposed, wire completely insulated, rubber hose, rusty nail and a paper clip
    After the experiment, we had to write down the current of the electricity, comparing different objects.

    Here is the predictions on the document.They show I and C




    Some of the conclusions of the experiment were that the predictions were right in all of them except one, electricity flows through graphite. Also, some of the materials flow more that the others. For example, the bar magnet ( +3 electricity flow) was more than pyrite (0.4 electricity flow) Diffrent people also got different results. For example someone got +3 for graphite and another person got +1.8 ( These numbers are the current current).

    It's All About the Energy

    The first thing that we learned in class was the test. Mr.Pro showed what we would have to study in order to get a good grade. He also showed us what question ( if you answered correctly) would get you an A.


    After that The class had somequestions on kinteic and potencal energy, so he decided to review.He spent soe time pointing at a form of energy and the class would say whether it is kinetic or potential. If we got it wrong, he would explain why the answer is the answer.
    When we were done Mr.Pro started explaining the activity. We had to get in to the groups given to us and then read a bout a form of energy which were:


    • Nuclear
    • Solar
    • Geothermal
    • Hydroelectric
    • Wind

    He gave us half and hour to read and fill out the form about the topic. WHen we were done we had to turn into different groups and explain our topic. The goal of this activity was to be an expert the topic given.

    Mr.Pro Explaining Kinetic and Potential energy.
