Scientific Method Worksheet

 

 

 

 

Read the following descriptions of experiments and answer the questions about them. You do not
need to actually perform any of these experiments, just answer questions about their design.
Experiment
You want to determine which disinfecting spray kills off more germs, Clorox or Lysol. You
spray two counters with juice from raw chicken. Then you spray one counter with Clorox and
one with Lysol. After the solutions dry, you wipe a cotton ball on the Clorox counter and then
wipe it onto a petri dish. You do the same with the Lysol counter and wipe it onto a separate
petri dish. You let the plates grow bacteria for several days, then count which plate has more
colonies of bacteria.
Questions
Name the Independent and Dependent Variables from the experiment above.
Name two good Control Variables you would keep track of in this experiment.
This experiment needs a Positive Control Experiment. (This means at least one more counter
and petri dish.) Describe what you would do to confirm that you can measure your experiment is
working as expected.
Create a hypothesis for this experiment. Remember that a good hypothesis doesn’t have to be
right, it just has to follow the rules. (Which spray will kill off bacteria best?)

Sample Solution

things to not be so accurate in the film. The speech and most of the photos would not have happened in the work of the fiction, due to the war’s ending. However, there were a few photos that support it through the earlier time period showing the way Hitler lived his life in Europe at the time of the invasion. Over the entirety of the film there are not many chances to see the front lines, but there are scenes that show the higher ranks of Nazi soldier’s parting or at films. In the photos represented in Germany at War in Color, the parties or gatherings were in a bigger area and had way more guards and security personal on watch, which the movie did not have. The entirety of the film was not similar to what the setting would have truly been.

Over the course of viewing the film I believe that the makers made the film with comedy and a big “what if” of what the war could have been like. The way that the movie was filmed with chapters, as if it were a book, was a twist on trying to make it more of a story or book that went off of different point of views, as the movie did. The way the characters were portrayed or acted was very stereotypical which added a comical side to the story. Whether it was the southern American Lieutenant Aldo Raine who was very stubborn, or Hitler who sported a cape and mustache and had an anger issue, it added to the comedy of the film. The addition of the different point of views was a good way of learning how each of the characters was developed and what they believed in or were after. The major reason I believe they made the movie for is the “what if” factor. The movie gives a great idea of what the war could have been like with the death of the leader of the Axis Powers, or how it would have been different if Americans were able to get an insurgent team in. The idea of a different outcome because of a different approach could actually help teach history by showing the different causes and effects that could happen from choices. It can show how ridiculously comical and easy the war could have been avoided. It also helped give a sort of an idea of how the life of a runaway “Jew” was like, or German leaders, and what spies would have experienced during WWII. This movie could be used in a history class as many things. It could be used as a sort of propaganda for what WWII could have been like. It could be used to show what certain people’s situations and lives were like in that time in Europe, under Nazi order. Lastly, it could be used as a comparison between facts and fictional beliefs.
