What conclusion can be drawn about an experiment that has been repeated multiple times with similar results each time?
The scientist made a mistake during the experiment.
The experiment will never be repeated by other scientists.
Each of the trials were completed by different scientists.
The results of the experiment are reliable or worthy of trust.
After reaching a conclusion, what should be the next step in any scientific investigation in order to verify your findings?
develop a theory
publish your results
form a new hypothesis
repeat the experiment
Scientists repeat experiments as part of the scientific process. Choose ALL FALSE statements about repeating multiple trials of an experiment.
Measurements and/or observations should be collected during each trial.
The goal of repeating an experiment is to find different results in each trial.
When repeating an experiment, the conditions need to be the same for each trial.
Scientists can verify their findings by repeating experiments through many trials.
To eliminate the possibility of hidden or unknown variables, the scientist must run a _______ experiment.
control
preliminary
test
variable
A average sneeze travels at about 100 miles an hour. Rebecca designs an experiment to increase the speed of sneezes. She subjects four participants to different stimulants: pepper, bright light, pollen, and fizzy soda. While the participant sneezes Rebecca measures how fast air traveled through the nasal passage.
What is the control in Rebecca’s experiment?
the four participants
the different stimulants
the speed of a typical sneeze
the speed of the induced sneezes
What is an observation you can make about about the cat?
The cat is black.
The cat is going to sleep.
The cat's name is Bennigan.
The cat has just had a meal.
A small gray kitten showed up at Lynn's house. Her mother told her she could keep it, so she checked the cabinets and refrigerator for food. She found some tuna and fed the kitten.
The next day her mother went to the store and bought some dry cat food. When Lynn put the cat food out, the kitten just walked away. "I think kittens like canned tuna better than dry food," Lynn said.
Did Lynn reach a valid conclusion about kittens?
No. One kitten is not an appropriate sample size.
No. Kittens can not eat dry food so her results are not valid.
Yes. Lynn watched her kitten closely and kept accurate observations.
Yes. Lynn's conclusion is accurate since it is based on how her kitten behaves.
A student notices that frogs are all gathering at one end of the pond. What has the student just done?
observed
experimented
hypothesized
collected data
When an experiment is repeated and the new results are different from the original results, what could you assume to be true?
The results from both experiments are worthless.
The first experiment's results are worthless and should be discarded.
The experimental design is flawed and the experiment should be discarded.
Neither test results are 100% reliable and additional experimentation is needed.
Why might a scientist repeat an experiment if he/she did not make a mistake in the first one? An experiment should be repeated to
increase income for increased work.
prove how interesting the study was.
ensure the results are accurate.
eliminate steps and save time.
A scientist is making observations. She is watching a variety of cat species. She is looking to see how cats benefit from their use of camouflage.
Which would NOT support a scientist's observations about camouflage?
a puma hunting at night
a black housecat hiding under the bed
a lion sunbathing during the day in the desert
a white bengal tiger running through the Siberian tundra
