Summary This week where doing an assignment called master mines it is a website where we find minerals and we had find out what the unknown mineral was by doing different tests on the mineral. While we did the tests it told us what each of the test do and what they are for and we took that information and transferred it ( in our own words) onto our Google doc. Surprise This week while we where doing our master mines we had to find out what the unknown mineral was by doing different tests on the mineral and when I found out that color was one of the tests I was surprised. I did not think that the color could help you find out what type of mineral it is. Backward I knew somethings about minerals like what the mohs scale is and how to test streak.I also knew how to test hardness and streak.Now I know what  color,luster,streak,hardness,structure,density,cleavage,and conductivity are and how to test them. Inward I feel good about my work this week because I had finished my m

Surprise This week while I was doing the boxes reasearch questions I had fiquered out the answer to that question it was sodium chloride but when I typed that password in it said I was wrong so then when Ms. Garcia and Miles R. told me that sodium chloride was another name for salt,I was very surprised becuase I did not know that but now I do. Summary This week in class we had to finish the boxes reasearch paper and the copmounds reasearch paper,and while I was finishing those I had learned that it is a mixture is when  it contains two (or more) substances that are not chemically joined together and it is a  molecule when  t he substances in a mixture can often be easily separated from one another. Backward Before we did this topic in science class I did not know very much about atoms or molecules or mixtures the only thing I knew before was that atoms where made of neutron,proptons and electrons. Now I know that m olecules are when two elements bond together and mixtu
