  1. what question were you trying to answer and why?
the question we were trying to answer was "what is the atomic mass of beanium. we were trying to get the mass of beanium so that we can know the atomic number.


2. what did you do during your investigation and why did you conduct it this why?


in our investigation we made sure to find out how much each group of beans weighed and the reason we did that was so that we can find the atomic mass of beanium.


3. claim = what is the atomic mass of beanium?
    reasoning = we found the atomic mass by finding the mass, percentage, and the average mass for each bean. after finding this info we put the data into an equation.
evidence = (1.5)(10) + (,42)(31) + (.23)(59)   divided by 100 = .41 grams

How do things like the concentration,size and temperature choose the speed of the reaction? In model 3, we placed 3 different glow sticks in 3 separate beackers. One hot, one cold, and one at room tempature. The glow stick that was in the hot beacker glad up almost automatically. The room temperature glow stick was second and the cold stick was third. It occurred this way because the hot beaker has allot more particles and allot more active then the cold or the room temperature. Another example could be example #2, in one experiment we crushed the seltzer and put it into water. And we did another experiment not crushing up seltzer and took allot longer to dissolve.

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 ...

1. what question were you trying to answer? how does the # of things around a central atom effect the shape of a molecule 2.what did you do during your investigations and why did you conduct it n this way? in this investigation we used our Ipad's that we have in class to do the PHET and after using it alittle we figured out what it was we had to do. 3. Claim = yes, the # of things around a central atom do effect the shape of a molecule Evidence = 6 things - octahedral 5 things -trigonal pair 4 things- tetrahedral 3 things- trigonal planer 2 things- linear 1 thing- linear # OF BONDED PARIS.
