Steps of the Scientific Method
What is always the first step of the scientific method?
Asking a question/making an observation.
What main liquid did Mark test in his experiments to see if sharks would be interested in?
Blood (both cow and human).
What was the first lab experiment we did yesterday?
Pulling the chemical shower and seeing how much water came out.
After a students wonders about how bumble bees find flowers, the student creates the statement: "Bumble bees find flowers by doing little dances to each other." He is now going to test this statement through an experiment. This statement is an example of a...
Hypothesis
What is Mr. V's full last name?
Voors
An educated guess that you test with an experiment.
Hypothesis
What two fluids did members of the boat crew donate in order for Mark to run his experiment?
Blood and urine.
If you pull the chemical shower handle down and walk away, will the water shut off?
No, it will keep spraying until manually pushed back up.
A student wonders why the sky changes color as the sun moves across the sky. This is an example of a...
Making an observation/asking a question
Is Mr. V married?
Yes, very happily.
This step is where we decide whether our hypothesis was correct or incorrect.
The conclusion
Was Mark's original hypothesis: "Sharks will form a feeding frenzy from a few drops of human blood." supported or unsupported by the end results of the experiment?
Unsupported. (No sharks visited any of the human blood boards)
When we have several points of data, what do we find with them to get the most accurate single answer?
The average
A girl designed a test to determine if her hypothesis, "Plants grow better in direct sunlight" is true or not. This test is an example of a...
Experiment
Is Mr. V from Lima?
No, I am from Van Wert.
The step we take after we have ran our experiment and collected our data.
Analyzing the data.
Mark made sure that all of the pumps for the experiment ran at the same rate and at the same time, and that the boards were all the same distance from the boat. These are all examples of what?
Controls (or controlled variables)
What two steps do you need to perform to get the average of several data points?
Add all the points together, and divide by the number of points.
A scientist has just finished collecting all of his data, and is now looking through it to look for patterns and interpret what they mean. This is an example of...
Analyzing results
What is one job Mr. V has had before teaching?
There are a lot of these, I'll tell you if you are right. I'm assuming you said zookeeper.
What is the name of the process that other scientists use to check the results of your completed experiment before it can be published?
The peer review process
So you are only testing one part of the experiment at a time.
What is the name of the property of water that allows so many drops to stay on top of the penny without spilling?
Surface tension
After a team of Norwegian scientists conducts an experiment where they turn lead into gold, other teams of scientists attempt to repeat their experiment but are unable to get the same results, and so reject their findings. This is an example of the...
Peer review process
What animal almost killed Mr. V when he worked at the zoo?
A giraffe. (She almost pulled me off of the Giraffe Platform.
