Keara’s class is modeling lava flow from volcanoes. Each of the three common types of lava has a different thickness. Keara and her classmates want to know if the type of lava affects how fast it flows from a volcano. Which variable should they test?

the size of the volcano
the thickness of the lava
the temperature of the lava
the location of the volcano

Keara and her classmates should test "the thickness of the lava" to determine if it affects how fast the lava flows from a volcano. This is because the thickness (or viscosity) is the variable directly associated with the type of lava and its flow characteristics.

A scientist has completed several trials to see how a new drug affects adults.

Which step will best assess the validity of his experimental design and results?

conducting more trials for the experiment
asking another scientist to replicate the experiment
changing the variables to determine how the drug affects children
conducting research to determine whether the experiment has been conducted before

The best step to assess the validity of the experimental design and results is "asking another scientist to replicate the experiment." Replication by an independent scientist can help verify the reliability and accuracy of the findings, ensuring the results are not due to chance or bias.

Abigail is testing the effects of three fertilizers on grass growth. She conducts multiple trials and collects data. Abigail would like to publish her research so gardeners will know which fertilizer to use on their grass.

What should Abigail’s next step be to validate her results?

repeat the experiment again to add trials
publish her research at local garden centers
ask a fellow scientist to conduct the same experiment
test the same fertilizers on other kinds of plants

Abigail's next step to validate her results should be to "ask a fellow scientist to conduct the same experiment." This step, known as replication, helps ensure that her findings are reliable and can be consistently reproduced, which is crucial for validating scientific research before publication.

Marcel conducts an experiment to test which stain remover works best on mustard stains. He wants to make sure that he does not make mistakes and has correct data in his experiment.

What should Marcel do to make sure that his data are correct?

conduct a similar experiment with a different washing machine
ask other students to conduct related experiments at their homes
ask his sibling to conduct the same experiment using his washing machine
repeat the experiment several times with the same variable and constants

To ensure that his data are correct, Marcel should "repeat the experiment several times with the same variable and constants." Repetition helps to confirm the reliability and accuracy of the results by reducing the effects of random errors or anomalies. It ensures that the findings are consistent across multiple trials.

To test the quality of water sources in her area, Shameka collects five samples from each water source and tests the quality of each sample.

Which important step of scientific design is Shameka conducting?

repetition
replication
verification of results
using controlled variables

The important step of scientific design that Shameka is conducting is "repetition." By collecting multiple samples from each water source and testing each one, she is ensuring that her data are consistent and reliable, which helps to account for variability and increases the robustness of her findings.

Candace is finding the boiling point of water. From her research, she knows the boiling point of pure water is 212°F. When she ran the investigation, she obtained the following results: 210°F, 213°F, 210°F, and 213°F.

Which word best describes her results?

accurate
exact
precise
wide-ranging

The word that best describes Candace's results is "precise." Precision refers to how closely multiple measurements are to each other. In this case, her results are clustered closely around the values of 210°F and 213°F, indicating precision. However, they may not be perfectly accurate, as they do not consistently hit the expected value of 212°F.

How can scientists best confirm and validate the results of an experiment so they can publish their findings?

by removing the control from the experiment
by adding more variables to the experiment
by decreasing the number of trials
by creating a replicable experiment

Scientists can best confirm and validate the results of an experiment by "creating a replicable experiment." A replicable experiment allows other scientists to conduct the same experiment under the same conditions to verify the results. Replicability is crucial in scientific research as it helps ensure that findings are reliable, accurate, and not due to chance or bias.

Which part of experimental design is most important to a scientist when replicating an experiment?

having exactly the same data as the previous experiment
using the same procedure and variables as the previous experiment
conducting an experiment similar to the previous experiment
using the same laboratory that was used in the previous experiment

When replicating an experiment, the most important part of the experimental design for a scientist is "using the same procedure and variables as the previous experiment." This ensures that the replication is as close as possible to the original experiment, allowing for a valid comparison of results and the confirmation of the original findings.
