Javier and Jessica are measuring the water temperature of a stream.
Javier records the water temperature as 56°. Jessica tests the water at the same location, but finds that the water temperature is 13°.
The students discuss how different their readings are and discover the problem.
What is the most likely cause of the different results?
Jessica's thermometer was not working correctly.
Javier put her thermometer in the moving water. Jessica had hers in still water
Javier was measuring in degrees Fahrenheit. Jessica was measuring in degrees Celsius
Javier made her measurements using a digital thermometer, while Jessica used a standard laboratory thermometer.

to learn how other students interpreted data
to replace original data with another student’s data
Which of the following would be an example of a scientist using creativity?
replicating the same experiment three times
copying the experimental design of another scientist
repeating an experiment written in a science journal
applying an experimental design to a different problem
