However, individual scientists do not submit their work to the scientific community before making sure they are right. How best can they ensure that their results are valid? a. Scientists hire editors to review their lab reports to make sure that their explanations are clear and concise and to change anything that doesn't sound good.
A basic principle for scientific research is that the experiment must be able to be replicated. What happens when an experiment is replicated? a. A scientist publisher accepts the experimental results for printing. b. No one in the scientific community agrees with the methods or results. c.
The scientists decide that the best way to complete the study is to create a model. Which of the following is the most likely reason that the scientists will use a model instead of creating an actual oil spill study?
After the invention of the microscope, doctors came to know that many diseases were actually caused by microscopic living organisms, like bacteria. What does this suggest about the nature of scientific knowledge? a. Scientific knowledge should not be considered valid because it changes over time. b.
d. Data from old experiments cannot be used in new scientific inquiries.
Scientific investigations can be made without observations.
It is a successful investigation because the data proved that weather conditions influence soil temperature. Jules wanted to know whether the eating behavior of goldfish is affected by music. He set up a fish tank. Every day, Jules played music for the fish and measured how much the fish ate.
c. Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. Keesha counted the bubbles released from the plant every minute for five minutes (min).
b. The lease effective colors of light for photosynthesis appear to be orange and red.
d. The process is a valid investigation because scientists used systematic methods for collecting and analyzing information.
A meteorologist who has been analyzing weather data from the last fifty years found evidence of climate change. An ecologist has been studying deposits of pollen from the last fifty years to track the types of plants that grew in certain regions. She has also found evidence of climate change.
a. Nina's observations are sufficient to form a scientific conclusion.
