Science Homework Help

In the discussion you should make a conclusion and then
explain how your experimental results and observations support your conclusion. The points
below should help you identify the information you have available from this experiment to
support your conclusion. Be sure to include:

a. A claim. Based upon the purpose of your experiment, what claim can you make using
your experimental evidence?

b. A table of your results. Include; expected, experimental, and % error in mass of NaCl;
expected concentration, absorbance, experimental concentration and % error in
concentration of the dye solution.

c. Discussion of your results.

i. Explain how your experiment results support your claims.

ii. Explain discrepancies between expected and experimental results

f. Uncertainty and Error in measurements.

i. Identify at least three (3) possible sources of uncertainty and error in this experiment.

ii. Use evidence from your laboratory notebook to evaluate the validity of these sources
of uncertainty.

iii. Discuss the error sources you have evaluated.

iv. Discuss how the direction of each source of error affects the results.

g. Supporting references that demonstrate the validity of your method.
