SESSION 1: What Is the Nature of Science? |
|
|
|
|
Scientists have been perplexed about the extinction of
dinosaurs. Many hypotheses have been developed to explain their demise. As you explore
"What Killed the Dinosaurs?," a Web activity, think about how scientists choose
the best explanation. |
|
|
|
When you are finished with this activity,
consider:
• |
How does this activity demonstrate the nature of science? |
• |
Which hypothesis has the strongest evidence to support it?
Explain. |
• |
Does any of the evidence refute this hypothesis? If so,
how? |
• |
How might scientists determine the best hypothesis to
explain the disappearance of dinosaurs?
After answering these questions yourself, visit the ENSI Web
site to learn about how scientists employ the model of fair tests. (A "fair
test" is one that doesn't have the same basis as any of the alternative solutions
that are being considered and one which could support two or more of the alternatives
being considered.) |
