1. What question were you trying to answer and why?
the question we were trying to find is which changes are examples of chemical change as well as physical change. We were doing this so that we can further understand the changes chemical and physical change.
2.what did you do during your investigation and why did you conduct it in this way?
during our investigations made sure to get all our supplies ready to go and conducted our experiment.
3.what is your claim, evidence , and reasoning?
claim: which changes are examples of a chemical change and which are changes of a physical change.
evidence: H2O + NACL = Chemical
copper changes = Chemical
NAoH + (CU(NO3)2 = Chemical
(HCI) + (NAHco3) = Chemical
paraffin wax + hot H2O = Physical

explore lab write up 2/12/18

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

3 question blog 2/16

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.
