Science Lap Buliding A Sizemograph

Hypothesis:

Can you design and build a seismograph that can record the movements of simulated earthquakes?

Prediction:

I think our seismograph will work and we will make it.

Materials:

• Cardboard box
• A couple of rubber bands
• Some safety pins
• A pen that is fine point
• Paper that has a chart system
• String 
• Tape 
• Toilet role  
• Knife

Procedure: 

1. Get all the materials that you need
2. Get the cardboard box and the knife and then cut the bottom of the box off and the one side of the box so you can see into the box.
3. Now get the knife and make one hole in two sides that are parallel and make three holes on the top of the box and make t in the shape of a triangle. 
4. Then get the string and put it through the top holes and then tape the ends of the strings to the pen and make sure the pen can touch the bottom of the box. 
5. Now get the rubber band and put one rubber band through the holes on the sides and then attach them to the pen and then on the outside of the box use the pin and put it on so that the rubber band doesn't go into the box.
6. After get the toilet role and the paper and tape one side of the paper to the role.
7. Ok now put the paper under the pan.
8. Now your almost done, now you just have to make the box shake and you have to pull the paper away from the pen.
9. And now you have waves recorded on your paper and you will know when a earthquake happens. 

Analyze and Conclude:

When we started to shake the table the pencil failed because we needed to put the cardboard on the bottom so the pencil didn't touch the paper so we had to glue and tape the card Bord on the bottom of it so the paper and the pencil are touching. We did tree tests the first test one was when we shakeup the table hard the pencil and the seismograph showed how strong is the earthquake.   

Communicate

Hello  everybody this is a new way of finding the earthquake this will develop the word it will show the exact how the earthquake occurred and how strong is it. This wasn't a big machine it is a small one it can fit in you room it is perfect for you.

 

Earthquake

There are very little earth quakes in Serbia the last one was in Kraljevo which occurred about 2 months ago, that made a big intact in kraljevo, almost all of the school were closed. My dad had made an exhibition so he could give some money to help kraljevo, he also organized them where they can sleep for safety. There were 100 kids from kraljevo that my dad helped to come and organize the tennis exhibition. 

Finding the Epicenter

I. GUIDING QUESTION/S (State the guiding question/s):

How can you locate and earthquake's  epicenter?

II.HYPOTHESIS:

I believe that, the epicenter of 3 cities will be approximated around Oklahoman

Materials:

Pencil

Compas
s

Map

Marker to locate

IV. RECORD & ANALYZE:

Data Table:

City	Difference in P and S Wave Arrival Times	Distance to Epicenter
Denver, Colorado	2 min 40 seconds	1400 km
Houston, Texas	1 min 50 seconds	1000 km
Chicago, Illinois	1 min 10 seconds	600 km

1. The factors are when the tectonic plates are rubbing on each other so that how geologists determine where the earthquake occurs.

2. Because the United Stats is big and when a earthquake and when a earthquake occurs where are waves that can effect a lot of country's in the surroundings, There are also tectonic plates.

3. Buildings are made in ground and when an earthquake occurs it may fall and injure people. A tree may fall and make a lot of damage. And the ground can creche and you can heart you.

My lab report

Lab Report Making waves  

1/19/2011

Guiding Question:How do water waves affect the objects floating in the water

Hypothesis: I think as the wave Hits the Boat and the floating objects in the water it will move them farther, And as i hit the water slower the boat and the object will not turn they  will rock.

Exploration  ( PLAN & DO A TEST):

(Materials) : 1. I will need a big bucket of water

                2. Make a tin foil boat and some building

                3. I will need sand

                4. A lot of water

                5. marker

(Procedure) :

1.  First you have to make a boats  out of tin foil. Second you have to take a big bucket, and insert water in it. Put the objects that you made in the bucket, Take a marker and start hitting the water and observe the boat and the water if nothing is happen take a bigger object and do the same thing, you will see as you take the bigger object you will see that the boat will flip or hit the bucket.         

IV.  RECORD & ANALYZE:

When i hit the water with the glue stick slowly it takes more time to get to the end, and as i hit stronger the faster the ball is traveling.

           A.  Data Tables:

                       Give proper title of table and column headings

Object:	Low Frequency	Time	High Frequency	Time
Ping-Pong	1 Hz	21.7	5 Hz	15.7
Wooden stick	1 Hz	51.4	5 Hz	21.7
Small boat	1 Hz	43.5	5 Hz	16.8

                       Use an appropriate orientation

                       Make correct computations

                       Use units of measure

                       Observe significant figures and rounding-off

                           rules

           B.  Graphs: Give a proper title and a legend for each  

                             axis

                       Use an appropriate orientation

           C.  Analysis of Data: As i hit the water harder the faster the boat and the other object are going. But as i hit slower the slower the boat and the objects are slower and hitting the edge of the bucket.

IV.  Concept Acquisition (CONCLUSION): In conclusion i think this wave lab will help me a lot.I can see that this unite was Cindi hard. I learned a lot of things. It was so hard trying to do all of the calculating and putting all of the data analyses on the

I learned a lot for a very short time. The int resting thing is how each material accede different. One pore the more you swing there is less the ‘’the wave is made’’

V.  Concept Application (FURTHER INQUIRY):  The only thing that i would change was my guiding question because i was in a hurry and did’t have much time to think. Every thing El's was good

Water Pollution

Over two thirds of Earth's surface is covered by water; less than a third is taken up by land. As Earth's population continues to grow, people are putting pressure on the planet's water resources. In a sense, our oceans, rivers, and seas are being "tortured" by human activities, which reduce its quality. Poorer water quality means water pollution.

We can define pollution in so many ways. Usually, it means that one or more dangerous substances occur in water to such an extent that they cause problems for animals or people. Oceans, lakes, rivers, and other inland waters can naturally clean up a certain amount of pollution by dispersing it harmlessly. But the problem is with big concentrations of dangerous chemicals. This, in turn, could affect the health of all the plants, animals, and humans whose lives depend on water.

Pollution can affect two types of water: surface waters and groundwater. There are also two different ways in which pollution can occur. If pollution comes from a single location, such as a discharge pipe attached to a factory, it is known as point-source pollution. Other examples of point source pollution include an oil spill from a tanker and a discharge from a factory chimney. A great deal of water pollution happens not from one single source but from many different scattered sources. This is called nonpoint-source pollution

Fresh water from National Geographic

We drink over a million liters of water,Gees what if we don't stop to pollute the water there will be water bu we are still polluting. You think you can Get through one day with out drinking water, get what you cant because you organism need water.

 We are wasting water or trowing it when we are not thirsty any more, But for a Africans kid life just if you don't throw the fresh water when doing that just thing of the people in Africa.

  A thirdof the people on Earth may lack a clean, secure source of water. Join National Geographic in exploring the local stories and global trends that define the world's water crisis. Learn about freshwater resources and how they are used to feed, power, and sustain all life. See how the forces of technology, climate, human nature, and policy create challenges and drive solutions for a sustainable planet.

Earthquake in Kraljevo

http://www.blic.rs/Vesti/Hronika/215100/Novi-zemljotres-jacine-28-stepeni-u-Kraljevu-proglaseno-vanredno-stanje

Last night a shocking thing happened. There was an strong earthquake that shook the whole Serbia. This earthquake happened at 01:58 after midnight, The earthquake was so strong that it was felt almost every city in Serbia.

The epicenter was 10 kilometers north of Kraljevo. The Serbian seismological institute measured that the magnitude of the earthquake was 5.3 at a relatively shallow depth of 10 km. In this tragic earthquake 2 lost t lives. Many of the buildings are damaged, so at the moment there is no electricity and they don't have much water.

From the firth earthquake until now there were 20 small quakes which were not so strong as the first one. The last one occurred around 09:00 in the morning. Kraljevo is  under the state of emergency, because people are afraid that maybe there will be more aftershocks.


I think this is very scary for Serbia because you don't know when  another one can happen. I hope this is the last quake that Serbia will ever have.

I woke up at 2 in the morning, my whole room was shacking. I thought  it was a dream, so I continued to sleep.
