Flame Test Lab

Introduction: Some metal ions can be identified by the color of their flame during a flame test. Different elements placed into a flame will turn the flame different colors.

Essential Question: What metals do colors indicate?

When solutions of a metal get burned they give off a certain color. When elements are heated the electrons take that energy and and move to an outer energy level. You can use the color that the element changes to when heated to identify the element.

Law of conservation of mass

iohjoi]

In each experiment we tested the Law of conservation of matter. In the first one after trial after trial the mass before mixing went down and after mixing the mass went up, after mixing the chemicals looked like white gell. in the second experimentwhen we put the white tablet in water and then that made gas. the mass went down a lot after shaking the bottle. One difficult thing i had to deal with was makng the air not effect the expirement while finding the mass of the water bottle. I conclude that the Law of conservation of matter is true.

Elements of a star

Where do the elements of stars come from? Before we watched this video and read the packet i had no idea where the elements of a star came from. Over many years the scientists are trying to figure out what caused the elements of a star to form and be the way it is now. Now seeing how our stars have been formed i am very interested in the solar system now. The Universe has come from many years of trial and error.

The universes elements all came from many different things. Although scientists think it all came from one thing, a Super Nova. this is what made our universe. The main element in a star is Hydrogen, where this is found in most stars. Another cause of stars are Nuclear Fusion to form a strong nucleus. With out stars our Solar System would not be able to function.
