1B: The Nature of Science - Scientific Inquiry**
**(grades 3-5, page 11)**
Scientific investigations may take many different forms, including observing
what things are like or what is happening somewhere, collecting specimens
for analysis, and doing experiments. Investigations can focus on physical,
biological, and social questions. (1 of 4)

Develop and apply a variety of strategies to solve problems, with emphasis
on multi-step and non-routine problems

Standard 1-3 page 137, Grades 9-12

Recognize and formulate problems from situations within and outside
mathematics

Scientists' explanations about what happens in the world come partly from
what they observe, partly from what they think. Sometimes scientists have
different explanations for the same set of observations. That usually leads
to their making more observations to resolve the differences. (3 of 4)

be confirmed and with a logical argument. (4 of 4)
