Science
• Science is a framework for gaining and organizing knowledge.
• Science is a plan of action — a procedure for processing and understanding certain types of information.
• Scientists are always challenging our current beliefs about science, asking questions, and experimenting to gain new knowledge. Scientific method is needed.

Concept Check
Which of the steps in the scientific method is missing from the following situation?
“Your instructor is holding a balloon and quickly inhales some of the gas inside the balloon. He then speaks and his voice changes to a high-pitched sound (and sounds quite funny!). He then asks you to determine what gas was inside the balloon that he inhaled. Based on your observations, you conclude that the gas must be helium.”
a) State the problem.
b) Make observations.
c) Formulate a hypothesis.
d) Perform experiments.
