What was the purpose of the experiment? Type your answer here:
Which properties are more useful in determining the identity of an unknown substance: intensive or extensive? Explain.
Type your answer here:
Write a hypothesis based on observations and scientific principles.
Type your answer here:
Experimental Methods
What tools did you use to collect your data?
Type your answer here:
Describe the procedure that you followed to conduct your experiment.
Type your answer here:
Data and Observations
Record your observations.
Type your answer here:
Conclusions
What conclusions can you draw about the identity of the unknowns? Write an evidence-based claim.
Type your answer here:
Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of knowns that were tested. Revise the experimental design by proposing ways to modify the experiment to increase your certainty in the identity of the unknowns.
Type your answer here:

Answer 1: The purpose of an experiment is to test a hypothesis.

Answer 2: Scientists commonly measure intensive properties to determine a substance's identity, whereas extensive properties convey information about the amount of the substance in a sample.

Answer 3: These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.

Answer 4: Data collection tools refer to the devices/instruments used to collect data, such as a paper questionnaire or computer-assisted interviewing system. Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data.

Answer 5: The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.

Answer 6: ?

Answer 7:  the first step toward teaching my students how to critically think about how they structured an argument or explanation was to implement the Claim, Evidence, Reasoning (CER) framework. While the premise behind CER isn’t anything new to the way science teachers already think, it provides an entirely different approach toward how students connect their experiences and previously learned content into something that is much more reflective of being scientifically literate.

Answer 8: ?

Explanation:

Hope this helped! :)

c. movement because i took the test and it lets me review my answers

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
