Daniel and Sanya are scientists. Daniel is studying whether the increasing frequency of tropical storms is affecting coastal erosion. Sanya is investigating whether the discharge from industrial plants has any impact on the pH concentration of freshwater swamps in the surrounding area.

Atoms are made of protons, neutrons,
and electrons. Although we can’t directly
see these particles, this structure
explains many experimental observations. This knowledge can be considered a

A student writes down several steps of the scientific method. Put the steps in the best order.
Communicate the results., Analyze the experimental data, Make a hypothesis, and conduct an experiment.
Make a hypothesis, conduct an experiment, Analyze the experimental data, Communicate the results.
Conduct an experiment., Make a hypothesis, Analyze the data, communicate the results.
Make a hypothesis, conduct an experiment, Communicate the results, Analyze the experimental data.
Which statement about the relationship between laws, hypotheses, and theories is true?
If a law is not contradicted after a lot of testing, it may be considered a hypothesis.
Laws that remain true over an extended period of time are considered theories.
If a hypothesis is not contradicted after a lot of testing, it may be considered a law.
A theory that holds true for a long time is considered a law.
Which sentence is a scientific statement?
People think there is life on some other planet in the universe aside from Earth.
Today, there are more viewers watching baseball than ice hockey on television
A tall glass of water tastes better with a lemon wedge and ice cubes.
Food cooked in ceramic pots has a better aroma than food cooked in copper pots.
Why is it important for scientists to keep testing a hypothesis even after they’ve found it to be true?
Experiments are rarely accurate, so it’s important to keep testing a hypothesis.
Scientists can learn experimental procedures through repeated testing of a hypothesis.
Repeated tests help determine whether the hypothesis is always true in different circumstances.
Repeatedly testing a hypothesis qualifies it to be accepted as a theory.
