Dynamic Earth

http://www.mnhsi.edu/earth/main_frames.html

 We are leaning about Earth in Science. Inside Earth it is really hot, and there are 5 layers. The hottest layer is Inner core. The Crust is thin as the apple's crust and it is the layer we stand on.The Mantle is the layer beneath the Crust and 84% of  Earth's volume is Mantle. The Core is the deepest and the hottest layer in Earth.
 Meteorites are mostly seen in midnight and they represent new messengers from space .They are formed at the same time and in the same way as Solar System and Earth, so they give us message about the origin of our planet.

  The peridotite rock is from the inner core, and it flies out with the lava when a volcano erupts. Diamonds grow by drops of water underground and when it gets old it turns into a solid and becomes a diamond. Diamonds can be found in underground or caves. Diamonds travel from the core to the top of the Earth with a rare magma called kimberlite and lamproite
  For me it is very intresting to learn about Earth and space .


 

Blog about leaning about Earth

I learned from the Bill Nye  that Earth has 3 layers and they're called core, outer core, mantle and crust. The temperature in the Earth is 1,500 degrees Celsius. Also the things that cause earthquakes are called tectonic plates. When a strong earthquake happens it's said you can feel it a bit on the other side of the planet.

What I want to know is a lot about volcanoes,  for example, what happens when the volcanoes erupt? Also how far can the smoke of the volcano go? Also, how far can a lava go ?

 

reflection on labs

For my making water wetter lab report grade I am satisfied with my results.  It was an interesting lab, but a hard one. Although I had mistakes , the information is quiet accurate and good. What went wrong is there was couple of confusions in my group.
    For Cooling races my grade was better than usual when  the labs are in question. What was good was we got to finish fast and nicely. There was  no trouble in the lab except the questions were difficult.

Magic show

For our magic show, me and Mateja did two tricks. I was in charge of a experiment where milk turns into different colors. To see the trick click the link below

Everything went nice except we wasted a lot of time emptying and cleaning the plate. The kids were excited for both for mine because it was nice and for Matejas because it was hard to believe, even I was amazed what happened.

  For my color milk this is why it does it: Milk has quiet big amount of surface tension which means it is pretty strong. That's why when we add food color it doesn't do anything. But, when we add soap it pushes the food color and milk to the edge.


You can do this at home.
WARNING: Do not drink the milk after the food color is added.

Simulation

 For the solid, liquid gas part, when you add heat to all molecules they start to spread and move fast. When we take away heat, the molecules slow down.  They are all the same because they all do  he same thing. They are different colors. At room temperature neon is moving kind of fast. At 25K the molecules start to connect and slow down.
 For the phase change, the higher the pressure the faster the molecules move and spread. When we add pressure the molecules squeeze together to survive. When the pressure is too high the molecules expand and break the top and fly around.

BacillaFilla - A Bacteria That Glues Concrete Walls

This article I found on Dogo news and it was posted by Meera Dolasia two days ago. This article is about a bacteria which a group of students in UK's New Castle University  created for gluing concrete together  or filling in holes in concrete. This bacteria was  created by genetic engineering   using an ordinary bacteria from soil. The name of this bacteria is BacillaFilla and it fills up the concrete cracks in the following way:

1. bacterias enter the hole and they cluster together
2. a hardening fiber is produced by this bacteria  and
3. a special kind of glue is created and it sticks everything together

This bacteria is still not on sale and that's a pity, because natural disasters are happening often and they destroy the concrete structures. For the time being, this ruined buildings must be completely thorn down or repaired with a new concrete whose production contaminates the environment. Imagine how easy would be just to put some bacteria in cracks and holes and wait for this wonder creatures to do all the repair work!

My mixture

In science class we had an assignment to create a mixture and to identify it. I made a mixture called Apfel Spritzer. This is a mixture of  apple juice and fizzy water. My mixture was homogeneous mixture and it was a solution. At the end I even got to share it with my classmates and they enjoyed it, they even wanted more but the teacher didn't allow. This assignment  was fun and I enjoyed tasting all these delicious mixtures.
