Growing Crystals
In my garden I have two medium size plants.I sprinkled one of them with the solution prepared by my science teacher. There were three solutions: the first one was made of sugar and water, The second one was made of salt and water, and the third one was made of borax and water. I used the mix of all three of them. On the first day,in my garden very few crystals have appeared. Crystals appeared on leaves of the plant that sprinkled by the solution. The crystals were small but very nice, and surprisingly grew on a real leaf. it took 24 hours for the crystals to form, and it is predicted that crystals will continue to grow. Today I sprinkled the second plant and i will check on it tomorrow. Yesrday I have also sprinkled the soil and the plastic flowers with the same solution but i haven't noticed any changes yet. It was also interesting experimenting with the colors of our crystals by adding the food coloring.

Questions and Asweres for Dinamic Earth
Diamonds
Q. How do gems grow?
A. Diamonds grow deep within the earth at high temperatures and pressures.
Q. Where are diamonds found?
A. diamonds are found in parts of Asia in parts of Africa Australia and in North America. They are not found in Europe.
Q. How do diamonds come to the surface of the earth?
A. Diamonds are carried to the earth’s surface by a volcanic eruption in a form of a rock called cimlurit.
Rocks and Mining
Q. Where do rocks come from?
A. Rocks come from the inner earth which is from the magma. When a volcano erupts the lava that dries becomes a rock and that’s where we get rocks.
Q. What is a mine and how does it work?
A. A mine is a underground tunnels where people dig out rock, copper, diamonds, etc
Q. What do we get from mining?
A. From mining we get many helpful things like, stone, copper, diamonds, carbon, etc
Q. Why do we need mining?
A. Mining we need so we could get these elements. Some of these elements are vital for humans and also for nature. Mining gives a lot of elements for building like stone, metal titanium and coal, etc.
Q. Why are there many types of rocks and colors?
A. Because it depends on there years it depends of where are they found
Plate Tectonics
17. What are the layers of the inner earth?
1. there are five layers on Earth : the crust that’s the layer on which we live on, then comes the upper mantle which is very warm and then goes lower mantle then outer core and inner core which is the nucleus of the earth.
Q. What kind of meteorites can tell us about space?
A. There are many meteorites in the universe which can tell us what is happening in the space.
Q. How do gems grow?
A. Diamonds grow deep within the earth at high temperatures and pressures.

What did I Learn this Week and What Would I Like to Know
This week was a very busy week, so my class and I have studied this week about caves and the earths crust. We have watched 2 movies from the same series of Bill Nye the Science Guide. I have learned a great deal of facts and science theories, about the earths crust and about caves. I have learned that there are 4 layers on earth the first is the crust which is the layer where there is life and the layer that is the thinness in width. After the crust comes the layer called the Mantle which is a gooey warm layer where magma is formed. Next there is the layer called the liquid outer core is much more warmer then the mantle. The liquid outer core is the 3 layer. And the 4 is called solid inner core which the the warmest which is the nucleus of the earth.
About caves I have learned a big variety of facts which were very interesting to me. I have learned that caves have very little of sun shine every year therefore many bats, owls, mice, and other animals. There are other types of cave animals:there are Troglodytes which are the cave lovers like bats bears and fish. There are also troglophies are cave dwellers which live deep deep in the dark of the cave which don't have any pigment and even they don't need it like crabs, fish, lobsters, and worms.
I would like how are rocks formed and i would like to know what calcium is in the dripping water of Stalactites and stalagmites, and would like to know how is the solid inner core formed.
