C GRADE A+ Q&A
Under what condition will the results of an experiment based on a hypothesis most likely
lead to new experimentation? - (correct answer)when the results do not match the
experimenter's predictions
For which question could a testable hypothesis be developed? - (correct answer)Does
all wood float in water?
A
law
describes something in nature and predicts how it will behave without explaining why. -
(correct answer)Law
Omar wrote a hypothesis about batteries called dry cells.
If more dry cells are connected end to end, a light bulb will work longer because there is
more energy available.
What are the variables in his hypothesis? - (correct answer)notThe independent
variable is the number of dry cells, and the dependent variable is the amount of energy
available.
Nathan hypothesized that if the temperature of liquid water increased, the density would
decrease because the volume would increase. He collected the data in the table below.
- (correct answer)not The data support his hypothesis, so he should investigate if the
same change happens in the density of solid water.
Which statement describes a scientific theory? - (correct answer)A theory changes
based on new observations and testing.
