Summary:
          A element is something that is made out of only one type of atom. Element's are things that can't be separated. There are over 100 different kinds of elements in the periodic table of elements such as things like gold and hydrogen. A pure substance is something that is made up of only one kind of  matter. Compounds are pure substances contain two ore more different types of atoms such as water. Mixtures are two more molecules that are not chemically combined and can be separated by physical means. An example of a mixture is iron fillings and sand by using a magnet to separate the two.

S&EP: SP3: Planning and carrying out investigations:
   I worked on play.lol  or an interactive game to find out different way that chemical reactions can happen and different signs of chemical reactions and what different reactions make different reactions make. In a chemical reaction you can mix different things to make different products. Some examples are mixing chlorine and mixing sodium to make table salt. You can also mix things with heat to make different products. Some different ways that you can know if there is a chemical reaction is things such as bubbling, extreme heat, change in color, consistency and more.

XCC: Cause and Effect:
          By causing a chemical reaction you mix two ingredients to make a different product. The reason that we have things like simple table salt is because sodium and chlorine got mixed and when they mixed the product was table salt. The reason that we have carbon dioxide is because oxygen and carbon met to make carbon dioxide. The reason why we have water is because of hydrogen and oxygen meeting to make water. The reason why we have some of the simple things that we do like water, salt and carbon dioxide is because of chemical reasons or two different things meeting to make something new.
