1. What question were you trying to answer?
the question we were trying to answer is "what are the identities of the unknown solutions.

2.what did you do during your investigations and why did you conduct it n this way?
During our investigation we used multiple different toothpicks which were codded in varies different metal ions. Each ion had different color when put to fire. The reason we did it this way was to figure out how each ion is different and which color they produce.

3.
Claim = what are the identities of the unknown solutions?
Evidence = 
Known metal ions
Color produced from flame test
Calcium
Orange
Barium
Lime
Copper
Dark green
Lithium
Red
Potassium
Peach
Sodium
Bright orange
Strontium
Red / Scarlet


Reasoning = Metal ion produce a distinct color of visible light when they are heated, The unique color observed when heated can be used to identify the ion. This is why we can use a tooth pic soaked in the solution to observe the unique color of the flame. Because we know the "identity" (color) of the known metal ions, we need only to match the color of the unknown to the corresponding color of the "known metal ion" to deduce the solution. In the case of solution 1, 2, and 3, the process was fairly simple; the unique color observed be easily matched to the known solutions.

Mark Rodriguez 1st period 2/12/18 1. what question were you trying to answer? Do average masses of different beans really equal standard quantity 2.what did you do during your investigations and why did you conduct it n this way? During our investigation we got multiple different types of  beans and we came up with data such as mass, relative mass, and average mas. 3. claim - yes, average masses of beans do equal a standard quantity justification - we think its a standard quantity because all the numbers are either 19, 20, 21. relative mass is the ratio of average mass and how many times the bigger mass  goes into the smaller mass. Evidence - Mass Quantity Bean type Relative mass Average mass 2.6 G 21 Cantal 1.0 G 6.52 G 5.8 G 19 Cyma 22.31 G 1.16 G 10.5 G 20 Black 4.03

1. I have worked on equations in class with the class to help us to get better at them. 2.molar mass equations, calculations, also learned how to solve and set up the equations with the correct answers. 3. I definitely think I need to ask more questions in class allot of the time when I don't understand something I don't really speak up about it. I'll definitely try to ask more.

3 question blog 4/6

1.what tasks have you completed recently? Recently we have completed the reactions rate explore lab, and did the drawings with the little time we had. 2.. What have you learned recently? Recently we learned learned how temperature might effect the speed of something desolving. 3.what are you planning on doing next to improve my understanding? I plan to make sure that I ask questions in class and try to understand it more then actually just getting it done.
