Periodic Elements.

This week we started a project that was our element baby book. It is a book based on our element's life. I am doing platinum and I learned a lot just by doing research. Platinum was discovered in 1735 by Julius Scalier. Platinum is a metal and it's atomic mass is 195.084 u. It's atomic number is 78. The number of protons is 78, the number of neutrons is 117, and the number of electrons is 78. Platinum's melting point is 3,215°F and it's boiling point is 6,917°F. The name of its family is Transition metals and the other elements in its family are Ruthenium, rhodium, palladium, osmium and iridium. Platinum is used in jewelry, containers and catalyst.

This week I made a table to keep my data on the periodic table in order and safe. I wrote down all of my data and I know where I keep it so I can reverence the text whenever I need to.

Matter matters

Summary: This week I learned that matter is anything that takes up space. Three states of matter are solids, liquids, and gases. Matter can change states. The most common way matter changes is temperature changes. If I had a beaker with an ice cube in it and heated it, it would melt and turn from a solid to a liquid. If I cooled the liquid, it would turn back to a solid. If I heated the liquid, it would turn into a gas. If I cooled the gas, it would turn back into a liquid. If I heated the gas, It would explode the lid of the beaker. So matter likes to change. The three main states of matter are solids, liquids, and gases. There are two more states. Plasma another one.

This week we were looking at different websites to find out more about matter.
I found out that matter changes all of the time. We were doing two different games.
One was a matter sorter. It would give me a tile and then I had to sort the tile into either
solid, liquid, gas or plasma. A pencil is a solid, soda is a liquid, air is a gas, and lightning is a plasma.

Mystery crystals

This week we were continuing our mystery crystals experiments. We were still trying to discover what the mystery crystal was. One of our experiments was to dissolve the crystals in water, pour out the water, and saw the remains of the crystals. The uno nown was really kosher salt. Then we started matter. An example of a chemical change is when you mix baking soda and vinegar. An example of a physical change is when you peel a banana. When you mix baking soda and vinegar, the atoms rearrange themselves to make something new. When you peel a banana, the atoms do not rearrange themselves and do not make anything new. 



S&EP: SP3: Planning and carrying out investigations
We asked ourselves, well, if baking soda makes a chemical reaction, then baking powder must do the same thing! We did the experiment and it worked! But not in the same way. The powder fizzed, but not in the same way that the soda did.
