 Rocky was a lonely little Metamorphic rock located on the side of a volcano off the coast of Hawaii. He was the weird rock that never really fit in he tried so many times to move onto other parts of the rock cycle but his so-called friends always said that you will never change from metamorphic to igneous rock. yet after today's rocky life was about to change and just like that he began to feel hot the volcano was erupting and he realized he was beginning to melt and due to the heat and pressure, he was turning him into Magma. While he was being transported down the volcano as magma. Rocky became excited because since he was melting due to the exposure of heat from the eruption he was becoming an extrusive igneous rock and also beginning his first steps to becoming a well-weathered rock. This was short-lived how every because he began to feel really cold. Soon he realized that he was changing and solidifying into an intrusive igneous rock. He then realized that he was beginning to...

 In our assignment this week we were tasked with discovering the different types of minerals and how to identify them. With our trusty mineral discovery kit as shown below, we were able to find a way to identify the minerals shown in our mineral organizer. This Kit has everything that is needed to identify the minerals being shown.  The best way I found was to follow a similar pattern every time you are trying to identify a certain mineral.  Is to just first observe the mineral under your tiny magnifying glass to see the shape, color, or what characteristics it has.  The next step is to find out if the mineral is earthy in color pearly or crystal-like these are all key ways to identify the mineral.  Next is using the streak plate to identify how hard the mineral is the streak plate, copper penny, and glass help show the hardness of the given mineral.  The last step is to check to see if it is fractured or cleavage. The difference is when cleavage is present...

 Back before we had all the key elements to such as satellites and cameras Scientists would have to find ways to see the planets, moon, and stars without this technology. This is how we are now able to have the technology to see earth and space and it is because of the Scientists a long time ago that discovered what was needed. Back in the day during the time of Kepler and Galileo the huge discussion topic did the earth rotates around the sun or does the sun go around the earth. This was a large discussion on this topic we had a famous millionaire at the time by the name of Tycho Brahe who created a database that was able to predict many key concepts in our solar system. He believed in a geocentric model or sun evolves around the earth. While Kepler believed in a Heliocentric model or sun-centered model. While they both created evidence to support their claim Kepler had the right idea but could not interpret parallax for his model so the geocentric model was still the best model un...

                                                          The length of our Solar System Over this week we found a way to put the distance between objects in our Solar system into perspective by using a different scale to walk out the distance between each planet and the sun. For this example, we chose to scale down miles into meters and this still was a very long distance between everything in our solar system, and when we got to the very end we could not see the sun from the end of the last planet. We used this as a comparison to show just how large our solar system is and how to put the distance into a perspective we can understand.  Below is a small chart that shows the distance between our sun and the planets around it. The AU stands for astronomical units is 149.6 Million Kilometers so our planets are spaced out a lot from one anothe...

                                                         Solar system  Over this until we discussed a lot about the Solar system and all of the parts that are part of our solar system. Also, that there is so much unexplored area outside of our own solar system. We use to believe that our Earth was the center of the universe yet we are only a small part of the infinite universe.  Below is an image of our very own solar system. While learning about our solar system we found the many different characteristics that each planet has such as Saturn having a ring around the planet or Jupiter being the largest planet in our own solar system.  During my next blog, I will be describing more about our solar system and just how far each of these planets is from each other. 

 Step one is to create a blog  step 2 is to post my pre-test  In the pre-test, I have answered 25 true false questions to show my prior knowledge of Earth Science.                                             Earth Science Pre-test  1.      We see because light brightens things. False     2.      The Moon goes around the earth in a single day.   False 3.      The amount of daylight increases each day of summer. False   This is False because it actually decreases each day because during this time the sun is moving away from the earth causing shorter days. 4.      The shadow of the Earth on the Moon is what creates the phases of the Moon we see from Earth. False   5.      People can see planets with the naked eye. true 6. ...
