Experimenting
Jonathan and Sarah have performed an experiment and are not sure their results are valid. What should they do to check their results?
A. average their data
B. repeat the same experiment
C. perform a new experiment
D. change their lab report
B
In __________, scientists study the MOTION of Earth and moon.
Physics
A group of middle school students were given a short course in speed-reading. The instructor was curious if a monetary incentive would influence performance on a reading test taken at the end of the course. Half the students were offered $5 for obtaining a certain level of performance on the test, the other half were not offered money. What is the independent variable?
Monetary incentive
The step-by- step instructions that are used to conduct an experiment are also known as?
A procedure
A chemist mixes baking soda and vinegar and noticed an instant reaction.
Observation
A scientist performs an experiment and asks other scientists around the world to replicate it. Why would other scientists most likely try to perform the same experiment?
A. to find out if weather of various regions of the world would affect the results
B. to see if the experiment would be less expensive in another part of the world.
C. to confirm the results of the experiment conducted by the scientist
D. to verify that the hypothesis of the experiment is a scientific law
C
State the two fields of science that are being described below:
Scientist A preserved a fossil from the ground and took it to Scientist B who placed it in an base solution to clean it up for microscopic investigations.
Geology and Chemistry
A group of middle school students were given a short course in speed-reading. The instructor was curious if a monetary incentive would influence performance on a reading test taken at the end of the course. Half the students were offered $5 for obtaining a certain level of performance on the test, the other half were not offered money. What is the dependent variable?
Performance on reading test
_____ _____ and ____ are used to collect, record and communicate data from the experiments.
Data tables and Graphs
A physicist tests three types of gases to see which one is the densest.
Experimenting.
Mandy wanted to see if a new environmentally-friendly pesticide will prevent insect damage to tomato plants. After making a hypothesis, she conducts her experiment. 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?
A. so that the hypothesis will always be correct
B. so that she can look intelligent when she presents her data
C. so that society does not waste money buying pesticides that don’t work
D. so that other scientists can replicate the experiment to make sure the results were accurate
