1. Errors that can appear well using the flame test. Scientist could mistakenly read the name of the chemical wrong and say the wrong colors. 

2. You need more than one property to find the answer to a substance.

3. the colors in the flames are produced from the type of substance if the substance is a high the color will be blue, red etc. if the substance slow then the color will be yellow, orange.

4. Mn, Sr, Cn, Co, Mg, Ba, Li

5. The element has to be heated by the flame before it can show color because the heat gives the element power and makes the electrons exited making them jumpy which creates light.

Where do elements come from?

Where did all the elements of the universe come from?
* Hydrogen, oxygen, and Helium
* They come from stars that explode. Combinations of the stars gasses created elements.

How did the universe form?

* Around all young suns, young stars, all combine, swirl around, the energy of the stars stirs them around, they first form particles, then that forms snowflakes, that formed little dust pieces which then forms rocks, which forms asteroids then eventually the asteroids turned into planets and moons.

How do I know/understand matter and what I know/understand about matter?

* Because earth is made from lava rock, magma and lots of elements such as hydrogen, oxygen, and H2O. Matter occupies space it’s a combination of mass and an object that takes up space.
