NATURE OF SCIENCE EXAM 2024 LATEST QUESTIONS AND VERIFIED
ANSWERS WITH COMPLETE SOLUTIONS
- other scientists can try to verify the results by repeating the same procedure.
When scientists conduct experiments, they share their data and conclusions with other
scientists so that
Having many replicates in an experiment decreases the possibility that chance
will affect the outcome.
Gregor Mendel was able to figure out a great deal about how traits are passed from one
generation to the next by studying garden peas. He grew thousands of pea plants and
counted and recorded the traits of all the peas they produced in order to do this. Why
did Mendel grow and use so many peas to conduct his experiment?
The experiment should be repeated, this time keeping accurate records.
Emily claims to have made a new scientific discovery. However, while conducting her
experiments, she did not keep accurate records or data. Which of the following should
happen next?
- results should not be accepted because scientific results should be repeatable.
Jasmine entered the school science fair competition. She wanted to see if colored light
affected plant growth. However, when several other students repeated Jasmine's
procedure, they all obtained different results than Jasmine's. What do the different
results mean?
, The scientist will lose credibility with other scientists and society.
When a scientist conducts an experiment, it is important that he or she maintains
accurate records and shares the results with other scientists. If this does not happen, or
if other scientists are not able to replicate the results, what would most likely be the
consequence?
Redo the experiments to see who is correct.
Two scientists are conducting similar experiments. The results of their experiments are
very different. Which of the following would be best for the scientists to do next?
- so that other scientists can replicate the experiment and make sure the results
are correct
Mandy wanted to see if a new, environmentally-friendly pesticide will prevent insect
damage to tomato plants. After making her hypothesis, she conducts her experiment.
She treats five tomato plants with traditional pesticide and five with the new pesticide.
Mandy also leaves five plants untreated as a control. She makes careful notes of how
she set up her experiment and then records her data about all of the plants. Why is it
important for Mandy to record her procedures and data accurately?
Her work must be repeated by other scientists.
A scientist makes a major new discovery that provides some evidence that a different
approach to gene therapy might be helpful. Which of the following should happen next?
Repeat the experiment and have one person drop the meter stick for all the
friends tested.
Alex and Jennifer conducted an experiment to test reaction times in grabbing a meter
stick after it is dropped. They each tested 15 friends. Alex dropped the meter stick for
