Dmitri Mendeleev and The Periodic Table of Elements

Image
Link To Image Website Summary:      This week in science we learned about Dmitri Mendeleev (the creator of the periodic table) and the periodic table. We learned that one of the biggest reasons Dmitri Mendeleev made the periodic table was because he wanted to put it into a science textbook and by making it into a table it would fit into the textbook. We learned that for periodic table instead of saying row and column we say period(for row) and family (for column). We also learned that about a pattern that the periodic table has which is that with each period there is one more energy level for electrons. Also that elements in the same family have similar chemical reactions. We also learned about what the periodic table consists of and the families within it. The periodic table consists of metalloids, metals, and nonmetals. The families are the Alkali Metals (Family 1), Alkaline Earth Metals (Family 2) Transition Metals (families in the middle), Boron Fa...

Science and Engineering Practices Quiz Re-Grade 8/25/17

      The first question I got wrong was:      1. Students at their tables read three articles about different communities that have instituted plans to conserve energy. They evaluate the information to create a plan for how their own community can conserve energy and share their plan during Student Exhibition Night.        I originally answered obtaining, evaluating, and communicating information. I realized now looking back at the question that it says that they "evaluate the information to create a plan." Because it says create a plan I realized now that the correct answer was planning and carrying out information. In the question it literally says the answer and I should've of realized that.      The second question I got wrong was:       2. After wondering about how the size of a magnet affects the number of paperclips it can pick up, a group of students develops a procedure that answers thei...

The Sulfur Cycle 1/20/18

Summary:        This week in science we learned about biogeochemical cycles, more specifically, I learned about the biogeochemical cycle known as the Sulfur Cycle. What I now know about the Sulfur Cycle because of what I learned this week through research is each part in the sulfur cycle. I also now know that their are a lot of different parts in the sulfur, but my focus was trying to make this complicated cycle very simple and easy to understand. The first part in the Sulfur Cycle is  Hydrogen Sulfide Gas is released into the atmosphere by the eruptions of volcanoes, hot springs (“ spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust. ”) , and the decay of living biological sulfur-containing materials in swamps, bogs, and tidal flats. Sulfur is also released from the ocean in sulfur-containing compounds in sea spray, and as the gas hydrogen sulfide. I also know that most of the sulfur released from the world's...
