Transcript of What is Science?
What do you think?
What does "science" mean to you? Define it in your own words.
I would say ...
Long Answer: Science is a systematic way of learning about the universe using testable explanations and predictions and a way of organizing that knowledge.
Short Answer: Science is the poetry of reality.
To think like a scientist is to think critically.
Demand, examine, and evaluate evidence.
Read your definition for "science" that you wrote earlier.
Write a new definition based on what you learned today.
Being skeptical means not accepting a claim as true until it is supported by sufficient evidence.
Can you think like a scientist?
Write on your paper...

This video was proven to be a hoax. There is no evidence to suggest that there are any surviving populations of mammoths.
Be a Critical Thinker
Skepticism is a shield that guards you against being fooled into believing things that aren't true.
The Scientific Method ...
... is how we minimize human error. We can all be fooled.
The scientific method is the way we make sure we aren't fooling ourselves.
Mammoths were cousins to elephants that are believed to have gone extinct in Siberia almost 10,000 years ago as the last ice age was ending.
Extraordinary claims require extraordinary evidence
