Science State Assessment

Cindy placed three beehives with the same mass into separate (but identical) glass containers. Hive A was kept at 100˚F, Hive B was kept at 0˚F, and Hive C was kept at room temperature (75˚F ) For the next month, she measured the amount of honey each hive produced. Hive C produced more honey than the other two hives.What is the test (INDEPENDENT) variable in Cindy's experiment?

• the temperature of each hive

• the number of hives

• the mass of each hive

• the amount of honey produced

What is the difference between a scientific theory and a scientific law?

• A theory is a well-tested range of representations and a law is a concrete physical representation.

• A theory is a well-tested range of observations of why something works and a law is a well-tested concrete explanation how things work

• A theory is a well-tested range of observations of how something works and a law is a well-tested concrete explanation of why things work

• A theory is a hypothesis that is yet to be proven false and a law is a hypothesis that will always be true.
